Apartment for the apartment Effective ventilation and heating of air

It’s not just about aesthetics when it comes to making our homes comfortable; it’s also about designing areas where we can flourish. The temperature we experience and the quality of the air we breathe are crucial factors in this. It is crucial to find efficient heating and ventilation solutions in apartments because there is often limited space and potential for restricted ventilation.

Having adequate ventilation is essential to having healthy indoor air quality. Pollutants such as dust, allergens, and even hazardous gases can build up in an unventilated space and cause discomfort and health problems. Inadequate ventilation can also lead to high humidity, which can encourage the growth of mold and harm the building’s structure.

Having effective systems in place for heating is crucial for comfort, energy efficiency, and financial savings—especially in colder climates. Optimizing heating while reducing energy consumption becomes a priority in apartments, where individual control over heating systems may be limited.

Thankfully, there are a number of methods and tools available to enhance heating and ventilation in apartments. Homeowners can customize solutions to meet their unique needs and budget by choosing from a variety of options, ranging from straightforward lifestyle changes to more sophisticated HVAC systems.

This post will discuss creative fixes and useful advice for improving heating and ventilation in apartments. We’ll go over tactics that can support you in reaching your objectives, whether they are to make your home more comfortable, boost energy efficiency, or simply improve the quality of the air.

Effective Ventilation	Heating of Air
Install exhaust fans in kitchen and bathroom to remove moisture and odors.	Use a combination of central heating system or space heaters to maintain warmth.

What are the recuperators

While recuperators of all kinds serve the same purpose, heat exchange technology varies greatly. Through heat transfer, recuperators differentiate between:

• plate;
• rotary;
• With ethylene glycol.

It is possible to install equipment on the roof or in the wall. Although roofing devices are structurally different, their working principle is the same.

Plastic

Plate recuperator and his work plan

Plate recuperators are the most widely used category of devices. The heat exchanger is a metal pollinated cassette with a high thermal conductivity indicator. The supply and exhaust air flows do not come into contact with one another because of the placement of the channels, but heat is still transferred through metal plates. The apartment’s clean air is facilitated by filters, and moisture drainage is provided by the condensate removal system.

Plastic recuperators can be installed in any room because they are typically fairly small.

Rotary

Corrugated steel makes up the apartment’s rotary recuperator for ventilation.

This type of device has a more complex heat transfer mechanism than the previous one, which results in much larger rotary recuperator dimensions and performance. Drive rotor movement is required for the device to function, which increases the equipment’s electricity consumption. Steel with corrugations makes up the rotor.

If there isn’t an extra hood installed on the system, the inflow and outflow of air can become mixed. In situations where the fan’s rotation speed is tunable, the air supply can be increased or decreased.

A recuperator with ethylene glycol

The third kind of device makes use of an additional coolant, which greatly boosts the machinery’s output.

Recuperator made of plastic and ethylene glycol.

A water-glycole solution circulates through the two heat exchangers in glycolic recuperators. The material can withstand a lot of heat. retains a lot more heat than metal recorders. If the weather is excessively cold, use antifreeze in place of ethylene glycol.

Since installing glycol devices is a complicated procedure, they are primarily utilized in large areas where air circulation will happen much more quickly.

Roof air recuperator

Warehouses, workshops, supermarkets, and other large-scale buildings use supply and exhaust ventilation systems with roof access. We refer to these gadgets as roofing recuperators. Recuperators are easy to install and operate. Such ventilation shouldn’t be more expensive than the plate system, which functions on a similar principle.

A private home’s ventilation system is private.

Since the exterior exit is located on the building’s roof, this type has the benefit of excellent sound insulation. A roof retractor can only be installed on private property because it is not feasible to set one up in an apartment.

How to make a tubular coaxial recuperator with your own hands

Apartment owners frequently opt for a tubular coaxial recuperator because of its easier design, which allows for independent manufacture and installation. The heat exchanger’s independent manufacturing technology is simple to use and just calls for rudimentary tool handling skills.

Tubular coaxial structure – pros and cons of

Advantageously different is the tubular recuperator with coaxically positioned membranes:

• increased to 65–70% of the efficiency coefficient;
• lack of mobile parts;
• compact design;
• accessibility of materials for independent manufacture;
• simplicity of manufacture;
• ease of installation;
• the ability to work without additional electrical equipment.

The second recuperator is a tubular one that is sufficient to make by hand.

There are additional drawbacks to the coaxial recuperator:

• the impossibility of changing humidity in the room;
• The dependence of the effectiveness of the device on the length of the coaxial pipes.

Necessary materials

The materials required for the independent manufacture of a tubular recuperator are available at any specialty store:

• plastic pipe with a diameter of 16 cm, used for sewage;
• adapters from a diameter of 16 cm by 10 cm, used as branches;
• a corrugated pipe with a diameter of 10 cm, made of aluminum; The size of the corrugated pipe should ensure its free location in the case
• Fan with a landing size corresponding to the diameter of the pipe.

Keep in mind that the recuperator’s efficiency is determined by the length of the channel when you purchase the materials for its construction. You can install a small fan to increase air circulation and work intensity.

Production of a tubular recuperator

Create a trumpeter’s diagram in advance for the device’s self-manufacture; this will help to prevent assembly errors.

When manufacturing, consider air flow movements.

Work while paying attention to the order of operations:

1. Cut the preparation of the plastic pipe of the required size, which is the heat exchanger body. Use a hacksaw for cutting a pipe
2. Pack the aluminum corrugation inside a plastic pipe, providing its maximum stretch.
   corrugated pipe is located along the entire length of the case
3. Fasten the adapters in the ends of the highway, connecting a corrugated pipe with them.
   Sectys are joined with the river operator corps
4. Ensure the tightness of the hoodie pipe to pipe pipe.
5. Connect the supply line to free pipe of the transition element. One of the assembly options for a coaxial recuperator
6. Coasten coaxial heat exchanger with a fan. This improves the passage of the air flow along the corrugation. Equipping the tubular recuperator with a fan increases the performance of the device

The suggested assembly plan will guarantee efficient heat transfer between the coaxial recuperator’s outer pipe and the corrugation walls.

Installation and connection of a recovery system

Sealant, aluminum adhesive tape, and a crimping clamp are used to attach the recuperator.

The type of device will determine how to install a recuperator. The device is mounted by analogy with other system components in the majority of cases. For instance, the following tools are required to install a plate recuperator, the manufacturing process for which was previously discussed:

1. With the help of a partner, the structure rises to the ceiling. Marking under the holes for fastening steel studs is performed. Next, holes are drilled, plastic plugs are clogged and steel hairpins are screwed up.
2. The recuperator rises again under the ceiling and is fixed at the desired height. For this, a steel plate is mounted between the studs, which will hold the recuperator by weight .
3. To connect the device to the air ducts system, it will be necessary to process part of the connected flange and a squeezing clamp with a solvent. After that, the inside of the clamp is smeared with sealant and fixed to the flange. Similarly, the duct is mounted to the recuperator . The joints of the joints are glued with aluminum adhesive tape.

Reimperor for a private house Views and selection criteria

Recovery systems can be classified into multiple types:

• plate devices;
• rotary systems;
• roof devices.

Every kind of air exchanger has pros and cons and is made for a specific environment.

Plane devices

These are the most widely used heat exchangers; they stand out for their remarkable dependability and have a straightforward construction. A private home’s plate recuperator can have a useful coefficient of up to 78 percent for metal and plastic models, and up to 92 percent for those with cellulose heat exchangers. The reason for the difference is that, as you may know, moisture has a higher warmth than heat, and cellulose exchangers return both moisture and heat to the air flow.

Note: To get rid of extra water, all air exchangers—cellulose excluded—need to be drained.

Lamellar device benefits:

• high efficiency of useful action;
• reliability in operation;
• Autonomous work without additional energy consumption.

• Plane exchangers are installed only in systems with hood and tributary;
• Such a heat exchanger freezes into severe cold and requires suspension of work for the time of defrosting (exception – pulp models);
• Rectors of this species do not return the humidity of the air flows (with the exception of cellulose).

Rotor devices

Rotating air exchangers: the second most common kind of device. The apparatus is powered by an electric motor and is constructed of aluminum.

The rotor’s flat and zigzag components are rotated by the drive belt. As the device travels through the hood area, every component heats up and transfers heat to the stream that is coming in.

Benefits of the rotating system:

• high efficiency of useful action;
• preservation of humidity of air flows;
• compact dimensions that allow the use of the device in small ventilation systems;
• the rotor does not freeze even with severe frosts.

• Dependence on electricity.

Roof air exchangers

A specific roof installation can be used to perform heat recovery in ventilation systems that use plate or rotary devices. These extremely efficient systems are usually installed in large rooms without internal partitions. The majority of these are hangars, sizable garages, or outlets.

The system draws air from beneath the ceiling and brings it back to a temperature that is suitable for human habitation.

Effectiveness is the clear benefit of this kind of air exchange, but private homes or apartments should not use such devices.

In every home, ensuring effective ventilation and heating of air is crucial for comfort and well-being. Proper airflow helps to remove stale air, pollutants, and excess moisture, while maintaining a consistent temperature throughout the living space. In apartments, where space is often limited, it"s important to optimize ventilation and heating systems to ensure efficient operation without taking up valuable room. By incorporating strategies such as installing energy-efficient windows, using programmable thermostats, and implementing balanced ventilation systems, apartment dwellers can enjoy a healthier and more comfortable living environment while also potentially reducing energy costs. Prioritizing effective ventilation and heating not only enhances indoor air quality but also contributes to a more sustainable and comfortable living space for occupants.

Types of air recuperators

The ventilation systems’ heat exchangers are made to be:

1. Rotary. This variety is a cylinder filled with corrugated steel. It is located towards the axis of the supply and exhaust device. The drum of such a heat exchanger constantly rotates, passing the alternately warm and cold air streams, as a result of which there is a recovery. Devices of this type are expensive and are usually installed at large industrial facilities.
2. Plate. This is the simplest in design and a cheap type of heat exchanger. Most often, the ventilation systems of private houses and cottages include precisely such recuperators. The device of this type consists of a large number of plates. The indoor air entering the housing heats them. The street flowing is perpendicular to him, he is warmly taken away.
3. Tubular. Heat exchangers of this type are also quite popular, simple in design and are not too expensive. Air recovery in them occurs on the same principle as in plate devices. But in this case, the stream passes through the pipes. At the same time, street air takes heat from their walls.

Different types of recuperators exist. All of them, though, have rather intricate designs and are primarily utilized in businesses, much like rotary ones.

Process description

It is vital to follow a specific sequence of events in order to ensure that the design is accurate and trustworthy. No particular knowledge is required, but creativity and quick thinking will be required:

1. The material is laid on a flat surface, divided by a cutting tool into square plates with sides of 20-30 cm. There will be several dozen such blanks. The plates are perfectly even when using an electrician.
2. Then wooden rails, cork material are prepared. Their parameters should correspond to the sides of the previously chopped squares. They are glued on the opposite sides of the workpieces, the latter remains empty. The process is suspended until the glue is completely drying out.
3. At the next stage, squares gather in a single cassette. Each sheet is neatly laid at an angle of 90 ° relative to the previous. The final element of the recuperator is a non -coal plate.
4. The prepared functional installation is fixed in the frame using a building corner.
5. The available holes, cracks, are treated with sealant, which prevents corrosion processes.
6. Be sure to make fasteners, fixing flanges on the sides of the cassette with plates. The lower part is equipped with a drainage opening through which a pipe with condensate is removed.
7. Cabinet walls are equipped with guides, which are made of durable corners.
8. After that, the prepared working part is placed in a box corresponding to the parameters.
9. Do not forget about the isolation material laid in the recuperator. It is firmly attached on the inside of the case walls of the structure.
10. Prevention of ice in the winter is ensured by installing the pressure sensor. It is usually mounted in the zone through which a warm air flow enters.
11. The final stage is the device ready for the use of the recuperator in the general ventilation system.

Such a unit has an efficiency of 65%. This is sufficient to produce a cozy microclimate in a cottage used for residential purposes. Remember that it is preferable to assemble the air recuperator by hand using the previously created drawings.

Residential and commercial buildings are outfitted with an enormous assortment of air conditioning systems. However, they could save money by manufacturing their own recuperator for the heat exchanger on their own.

Types of the system

Although recuperators come in a variety of designs, they all function to heat the air that enters a room by absorbing the heat from blurred or contaminated air masses. The recuperator must stop airflow mixing at the same time.

Plastic recuperator

Such a device has the most straightforward design possible. Good heat transfer between air flows is achieved by separating two heat exchanger chambers from another small plate.

Model made of plastic

Efficiency is one of this kind of device’s primary parameters, and it depends on things like:

• the time and area of heat transfer between air flows;
• thermal conductivity of the material.

Installing more heating elements can improve the efficiency of heat transfer:

1. The efficiency of a modern recuperator should be approximately 70-80 %.
2. However, it is not difficult to achieve such indicators in a private house.
3. The additional use of soil heat exchanger will be very effective.

The role of the ground heat exchanger

The plastic pipe that serves as the soil heat exchanger is placed 50 meters away from the house at a depth of about 2 meters. It has a few subtleties:

• Air sampling using a soil heat exchanger system can significantly increase the efficiency of ventilation with heat recovery;
• This design helps to avoid the formation of ice and condensate on the heat exchanger of the ventilation system;

Take note: You can lessen the temperature differential between the supply and output air flow by using the soil heat exchanger.

• If you do not provide in the ventilation system of a private house the presence of a soil heat exchanger, then avoid the formation of condensation due to the temperature difference, as well as the increase in the cost of heating the incoming flow, will be difficult;

Counseling! If the ventilation system does not have such a design, temperature sensors, automation systems, and calorifiers can be used to heat the air.

• In such a situation, the air of excessively low temperature will heat up due to specialized devices. Ensures the maintenance of the optimum air temperature during the year

An article about the subject:

Locating the ventilation valve helps keep different odors out of the house. We’ll attempt to explain what it is, how it functions, the different kinds of devices, and how challenging it is to install in your house in this post.

Decentralized recuperators

It makes sense to use more compact devices in apartment buildings to facilitate room air exchange. That’s where decentralized recuperators come in handy.

The designs are incredibly small and can be installed completely undetectable on the side of the window, beneath the windowsill, or on the incline of the window opening. When installing plastic windows in the room, it is advised to use it. The room’s air temperature is unaffected by the recuperator.

"Window air"

Rotor recuperators

The most efficient recuperators are rotor type ones. Their construction ensures that the specialized mechanism rotates by allowing the inbound and outgoing air flows to flow independently of one another.

This article will go into great detail about the different kinds of structures, the working principle, how to pick a location for the installation, how to install the device correctly using your hands, and helpful advice from experts.

Strength causes the heat exchanger to heat rotation from the side of the incoming air flow, ensuring further heating. These devices have an efficiency of 80–90%.

The typical mechanism’s wall length is between 20 and 30 centimeters.

Although the choice is made on an individual basis, at least 70 pieces are advised. The gasket between the plates has a thickness of 3–4 mm.

The method will be more effective the larger the pipes’ cross section.

Remember that there should be no obstructions to the air circulation at the input and output when choosing the box’s specifications. Ascertain beforehand where corners and fasteners should go.

Why a recuperator in an apartment of devices

Ensuring the proper ventilation of the room is the recuperator’s primary function. Utilizing equipment has numerous additional benefits and serves several purposes.

• Electricity savings;
• Improving. Instead of spent warm air with a low oxygen content, the apartment is filled with fresh;
• Heating. The device fills the apartment with warm air, even if -30 degrees on the street;
• Air cleaning. Eliminates the room from unpleasant odors and dirt in the air;
• Unlike ordinary ventilation, during the exchange of air masses, dirt from the street, dust, insects, as well as drafts, do not get into the house.

Heat transfer happens naturally during recovery; heaters are not needed. The air’s chemical makeup is unaffected by the heat exchanger.

How it all started

Eighty percent of the time, the windows in my nine-year-old home with natural ventilation were left open. Why do you say that? A nod valve was installed in the living room of the first floor, and two window valves were installed in the second floor; however, the tributary through the valve was insufficient, so I had to open the windows. The house is quite sealed and uses very little for heating. The ventilation was made up of just hoods in the form of fans in the bathroom and technical room, but still needed an air flow.

The barrels were robust enough in the intense cold of their valves, so to. There is an adjustment of them covered, and ventilation deteriorated as a result.

I use the carbon dioxide concentration meter that an individual exhales to evaluate the quality of ventilation; if the CO2 concentration is normal, then the remaining indicators will also be normal.

Here are some excellent articles about CO2 concentration:

It thus became evident that supply and exhaust ventilation was the best method.

It was determined to create a number of air through trial and error in accordance with AVK standards.To the greatest extent possible, these claims are based on "scientific engineering," and the CO2 sensor confirms this in general.

REPERTER what these are the main spheres

These plates can be used in any kind of ventilation system, depending on the device’s model, the installation location, and the size of the space.

The gadget can do multiple tasks at once.

The device improves the flow direction and is utilized in traditional ventilation blocks.

Our device simultaneously assumes multiple roles:

3. Automatic control system.

Air purification filters are also installed in the ventilation system.

Two air ducts are raised as part of the house’s internal ventilation system, allowing contaminated air masses to collect beneath the roof and be removed from the building altogether into the atmosphere.

The gadget uses a heat exchanger to function.

In these systems, a soil heat exchanger is used to provide "winter-summer" heating.

Recurator for a private house and apartments: Advantages

The cost of heating the room is significantly decreased by installing the ventilation system.

The exchange of air within a suburban building Be mindful! Installing a ventilation system with natural air exchange will be far less expensive than purchasing ventilation with an integrated recuperator.

1. The use of the device will significantly increase the effectiveness of the heating system of the room and reduce the cost of heating.
2. Rectors for apartments allows you to achieve an optimal level of air humidity, which will favorably affect the health of residents.
3. In modern multi-apartment residential complexes, you can often find monoblock supply and exhaust installations that are used to create a ventilation system of the house.

Such a system has the potential to employ plate rotary heat exchangers.

Permits an 85% reduction in heat leakage through ventilation.

Types, principle of operation and device of recuperators

It was a very good idea to heat the street using the heat from interior air. It served as the foundation for every recuperator’s work.

Three categories of these devices are currently in use:

• plate;
• rotary;
• Recirculation water.

The most widely used and straightforwardly designed are lamellar recuperators. They depend on energy, are small, dependable, and have an efficiency of between 40 and 65 percent.

This type of device’s primary component is a cassette that holds parallel plates. They divide the air entering the room and exiting it into small streams, each of which passes through a separate channel. Through the plates, heat exchange takes place. The heated air from the street is cooled and released into the atmosphere indoors.

The plate recuperator’s operating principle

Freezing during extreme frosts is the primary disadvantage of the plate installations. A recovery unit’s condensate setting turns to ice, which drastically lowers the device’s performance. There are three strategies to counteract this phenomenon.

The Bypas valve installation is the first step. He releases a chilly stream that goes around the block after receiving a signal from the sensor. All that is visible between the plates is warm air that is melting ice. Once the condensate has thawed and been removed, the valve allows the system to operate continuously again.

Using hygroscopic cellulose plates is the second option. Water that settles on the cassette’s walls is absorbed by them and seeps into the channels that the supply air travels through. Thus, the removal of moisture and condensation solves two problems at once.

The third technique involves first heating the cold flow to a temperature where water cannot freeze. Place the heater inside the supplying ventilation channel to accomplish this. When the street air temperature drops below -10C, it becomes necessary.

Plate reversing installations have become available on the market in recent years. They function in two ways, as opposed to direct-flow devices: first, they release warm air into the street, and then they absorb cold air through the warmed block.

The reversing installation’s operating principle

Rotating recuperators are an additional category of installations. These devices have an efficiency that is much higher than the plate’s (74–87%).

The rotary installation works on the principle of rotating the cassette while the air is flowing in and out of the cells. The channels flow in a circle, passing warm inner flows and cold outer flows alternately. Here, moisture saturates the supply air rather than freezing.

It should be mentioned that you can smoothly adjust the heat transfer when using a rotor-type recuperator in the supply and exhaust installations. produced by varying the cassette’s rotational speed. The primary disadvantage of rotary systems is their high maintenance costs. They are also less reliable than the plate in terms of consistency.

Water recirculation installation is the next kind. She is the hardest to design. Heat transfer is accomplished with the use of water or antifreeze rather than plates or rotors.

On the exhaust channel is the first liquid-air heat exchanger, and on the suction is the second. The idea behind the work is the califfer effect, in which heat from indoor air warms water and the street.

Such a system’s efficiency is between 50 and 65 percentiles below the plate recuperator indicators. The single benefit of such an installation—that the blocks can be arranged in supply and exhaust ventilation sections that are separated from one another—justifies the high cost associated with the design’s complexity. This is crucial for robust industrial systems. These kinds of devices don’t fit in tiny buildings.

The scheme and principle of operation of the supply and exhaust ventilation system with a rotary recuperator

Which recuperator is better

Today there are recuperators of different companies of manufacturers that differ in many points: the principle of work, efficiency, reliability, savings, etc.D. Let"s look at the most popular types of recuperators and compare their advantages and disadvantages. 1. Plastic recuperator with aluminum heat exchanger. The price of such a recuperator is quite low compared to other types of recuperators, which is undoubtedly one of its tricks. In the device, air flows do not mix, they are separated by aluminum foil. Of the minuses, not high performance at low temperatures should be called, t.To. The heat exchanger periodically freezes and must often thaw. It is logical that electricity costs increase. It is not advisable to install them in residential premises, t.K in the winter period during the work of the recuperator, all moisture from the air of the room is removed and its constant moisture is required. The main advantage of aluminum lamellar recovers is that they can be installed for ventilation of pools. 2. Plastic heat exchanger. The advantages are the same as the previous option, however, the efficiency is higher due to the properties of plastic. 3. Plate recuperator with a heat exchanger made of cellulose and a single cassette. Despite the fact that air flows are separated by partitions from paper, moisture calmly impregnates the walls of the heat exchanger. An important advantage is that the premises enters the room and the savings and moisture. Due to the fact that the heat exchanger is practically not subject to freezing, time is not spent on thawing, the effectiveness of the device is significantly increased. If we talk about the shortcomings, then they are such: recuperators of this type cannot be installed in pools, as well as in any other rooms where excess humidity is observed. In addition, the recuperator cannot be used to drain. Very often, such recuperators are installed for ventilation in the apartment.4. Rotor recuperator. It differs in high efficiency, but this indicator still remains lower than if the plate installation with a double cassette was used. A distinctive feature is low energy consumption. As for the shortcomings, we note such moments, since the oncoming air flows of the rotary recuctor are not perfectly separated, a small amount of air removed from the room (albeit insignificant) enters the supply air). The device itself is quite expensive, t.To. Complex mechanics are used. Finally, the rotary recuperator should be served more often than other supply and exhaust installations and its installation in wet rooms is not desirable.

What the price of the recuperator depends on what depends

First of all, the price of a recuperator depends on the performance of the entire ventilation system. A professional designer will be able to develop a competent project that satisfies precisely your conditions and requests, on the quality of which not only the efficiency of the entire system will depend, but also your further costs for its maintenance. Of course, the equipment can be selected by yourself, including air ducts and gratings, but it is desirable that a specialist is involved in the designated issues. The development of the project costs extra money and at first glance to someone such expenses will seem quite solid, but if you count how much money will remain in your budget due to the competent one, you will be surprised

Before selecting a recuperator on your own, consider the cost and the quality that is assured. Is a device worth the stated sum of money? Or perhaps you simply overspend on a novel brand or item? Since the equipment is expensive and pays for itself over time, careful consideration should go into selecting the device.

Make sure to ascertain the duration of the warranty period and the availability of products. Usually, the components of the recuperator are guaranteed rather than the recuperator itself. The cost of the purchase will increase with the quality of the assemblies, other components, and component parts. The system’s dependability is assessed based on the products’ strengths and weaknesses. No one provides a perfect, natural solution, but it is possible to identify the best option for a given space.

Features of work and operation

The power supply network must always be connected to the recuperator. Because of the remote control panel, using the device will be as convenient as possible. Typically, a remote control has four buttons:

Schematic of the recuperator’s internal mechanism

• 2 performance settings buttons;
• 1 button VCL/Off;
• 1 Summer mode button.

The heat exchanger’s material, system, and cassette surfaces all directly affect the device’s efficiency.

Advice: When making a purchase, you should focus particularly on the cassette’s area. The cold supply air heats up more quickly and powerfully the larger the heat exchanger’s area.

The best household recuperators

It is advised to install small rotary models for household needs because plate recuperators require the organization of a full-fledged ventilation box, which is not always possible in private homes.

The device’s heat recovery scheme

What is heat recovery, then? – Recovery is the process of heat transfer, whereby the apartment’s outgoing stream causes the cold street air to warm up. Heat recovery installation saves heat in the home because of this organizational scheme. Almost instantly and for very little electricity, a cozy microclimate is created in the apartment.

Below is a video demonstrating an air recovery system.

Describe the recuperator. general idea for non-experts.

Other factors determine whether a recovery heat exchanger is economically feasible:

• energy prices;
• the cost of installing the unit;
• costs related to the maintenance of the device;
• duration of operation of such a system.

Take note! An apartment’s air recuperator is a crucial component, but it’s not the only one needed for efficient ventilation in living areas. Heat recovery and ventilation is a complete system that can only function when a qualified "ligament" is present.

Head of the household

The unit’s efficiency decreases as the outside temperature drops. That being said, a large temperature differential "loads" the heating system, so the recuperator for the home is essential during this time. An air flow that is warmed to +16 °C is supplied to the living area if the window is at zero degrees Celsius. An apartment’s household recuperator handles this task without any issues.

The following formula makes it simple to determine the unit’s effectiveness:

The efficaciousness formula

Contemporary air recuperators vary structurally as well as in terms of efficiency and subtleties of operation. Think about the most widely used solutions and their attributes.

Handcrafted Air Home Head of the House

From the perspective of implementation and subsequent equipment, the plate-type heat recovery system is the simplest. This model has both glaring "minuses" and clear "pluses." When discussing the benefits of a solution, even a homemade river of air for the house can offer the following:

• decent efficiency;
• lack of "binding" to the mains;
• structural reliability and simplicity;
• accessibility of functional elements and materials;
• Duration of operation.

Prior to constructing a recuperator by hand, you ought to make clear the drawbacks of this particular model. The creation of glaciations during intense frosts is the primary shortcoming. There is less moisture in the air outside than there is inside the room. It becomes condensate if you do not intervene in any way. A high relative humidity aids in the formation of ice during frosts.

The image depicts the process of air exchange.

There are multiple strategies to prevent the recuperator’s device from freezing. These are compact solutions that stand out for their effectiveness and mode of application:

• the thermal effect on the design due to which ice is not delayed inside the system (the efficiency falls by an average of 20%);
• mechanical removal of air masses from the plates, due to which forced heating of the ice is carried out;
• Addition of the ventilation system with the recuperator with cellulose cassettes that absorb excessive moisture. They are redirected to housing, while not only condensation is eliminated, but the effect of a moisturizer is also achieved.

1. Aluminum sheets (textolite and cellular polycarbonate are quite suitable). Pay attention to the fact that the thinner this material will be, the more efficiently the heat exchange will be carried out. In this case, the supply ventilation works better.
2. Wooden rails (width of about 10 mm and up to 2 mm thick). Placed between neighboring plates.
3. Mineral wool (up to 40 mm thick).
4. Metal or plywood to prepare the body of the apparatus.
5. Glue.
6. Sealant.
7. Metiza.
8. Corner.
9. 4 flanges (under the cross section of the pipe).
10. Fan.

Please take note that the recovery heat exchanger’s width and diagonal match. The height is modified in accordance with the quantity and thickness of the plates as well as the rails.

Types of structures of recuperators

Depending on the heat exchanger device’s technical specifications, the recuperator’s operating principle varies.

Plastic structure

It is comprised of a set of aluminum or steel heat-conductive plates packaged together. High-temperature air warms the surface of the heat exchanger plates by imparting thermal energy. Masses of cold air absorb heat. The device’s design eliminates all mobile components, greatly enhancing the dependability of the work. Popular because it’s highly effective and inexpensive. The recuperator achieves a useful action coefficient of 65%. The plate recuperator has made a strong impression on modern cottages and private homes’ ventilation systems.

The sealed housing contains the package containing the plates.

Rotor type device

The recuperator’s cylindrical heat exchanger drum composed of corrugated steel elements is a useful feature. The supply and exhaust fan that moves heated and chilled air cyclically houses the drum. An efficient exchange of thermal energy between airflows and a partial return to the room takes place when the heat exchanger rotates. The electronic system of the rotor-type recuperator allows it to automatically adjust the rotor speed. This gives you control over the thermal return intensity and raises the device’s efficiency to 87%. Rotary recuperators are utilized in industrial settings and are known for their higher cost.

Tubular performance

These kinds of devices are very popular because of their straightforward design and inexpensive cost of independent manufacturing. Plate heat exchanger recovery and the exchange of thermal energy of air flows share a similar principle. The device’s tubular design allows air to circulate through coaxial pipes. Heat from the walls of the pipes heated by air masses is absorbed by the outside air. Private homes and apartments often have tubular recuperators installed.

Recuperator of the pipe type using coaxial pipes

Recirculation heat exchanger

This type of design uses the liquid as a medium through which thermal energy is transferred. This makes the design much more difficult. There are two heat exchangers on the apparatus. Two are installed, one on the exhaust ventilation line (filled with antifreeze or regular water) and the other on the absorption channel (through which the outside air enters). The heated liquid transfers heat to the air masses. The device’s forced coolant circulation design restricts the range of applications it can be used for. The utility coefficient is correlated with the plate structure’s recuctor’s efficiency.

The recuperator for recirculation is made up of independent blocks joined by highways.

Roof recuperator

This kind of industrial installation, with an efficiency of up to 68%, is utilized in the air supply systems of retail establishments and manufacturing plants. Low maintenance costs and ceiling space savings are two benefits of this type of recovery system, which are especially important for production workshops and retail establishments. The roof recuperator’s design prohibits its use in private residences’ and apartments’ air supply systems.

Ways to improve ventilation

To make the equipment more comfortable to use, there are a few ways to enhance its functionality. Energy consumption will undoubtedly rise as a result of these actions, but effectiveness will also rise.

Special filters made of fiber, plastic, or aluminum can be installed in the recuperator’s channels to remove dust particles from the air entering the device. However, you have to adhere to these components and replace them as needed.

By periodically shutting off the supply fan, you can prevent the structure from freezing. Due to the warm air coming from the output, this will cause the plates inside the mechanism to warm up and eventually thaw.

If all of the aforementioned advice is followed, a high-quality and dependable recuperator model will be produced, and the manufacturing process won’t require a lot of time or work.

How to make a recuperator yourself

Air recovery devices are pricey pieces of equipment with a lengthy payback period—three to five years for less expensive models and more than eight years for more costly ones. But, if you have even a rudimentary understanding of technology and installation, you can build an air conditioner for your house on your own and drastically reduce household expenses.

The simplest method for building a structure on your own using a plate river. You’ll need the following for this:

• Material for plates-sheet metal 0.5-1.5 mm thick, sheets of gateinax or textolite, plastic (cellular polycarbonate or polypropylene)-6.5-7 m2;
• Material for gaskets with a thickness of 2-3 mm, no more than 10 mm wide-spent wooden rails, technical cork, cord, plastic, plexiglass;
• Material for the case – plywood, tin, chipboard, MDF, plastic;
• Four flanges under the pipes of air ducts;
• Corner for racks;
• Neutral sealant (silicone);
• Glue;
• Insulation – roll and mineral wool (glass wool);
• Two filters;
• Two fans;
• Fasteners.

1. Cut square plates with a side of 200-300 mm. It will take about 70 pieces. A prerequisite – workpieces should be the same size, have even edges without bends and burrs. Therefore, it is better to use the power tool and cut several sheets folded by a pack at once.

1. The gaskets are cut into the size of the side of the square.

1. In addition to the latter, three stripes of gaskets are glued to each plate, except for the latter – along the opposite edges and the middle.

1. Previshes are collected in the block. For this, the top of the strips is smeared with glue. Put the panels on each other, turning each subsequent one 90 degrees and leveling the edges. The latter glue the plate without gaskets. To increase strength, a load is put on a cassette while dries.

1. They tighten the cassette with corners. The cracks are filled with sealant.

Heat exchanger made of plastic (cellular polypropylene)

1. Collect the case. The inner height and length of the box is equal to the diagonals of the plate heat exchanger, and the width is its height. If filters and fans are installed in the case, then it is necessary to provide a place for them.

1. Four holes (usually two in the side walls) are cut in pre -provided places, into which flanges insert. The joints are treated with sealant.
2. Mount the mount for the heat exchanger. Since condensation is formed in it, the working position should provide free fluid flow. Have a heat -expanded block in an upright position on the edge, the angle between the edges of the plates and the bottom should be 45 degrees. Directors for the heat exchanger made of the corner are attached to the walls of the case. So the block of the plates can be free to get for service.
3. A small hole is cut out in the lower part of the box and a condensation is removed.
4. Collect a recuperator. Ensure the tightness of the formed four compartments so that the movement of air masses is carried out only through the channels of the heat exchanger.

The recuperator’s assembly

1. Fans and filters are installed at the input of the flows – you can mount them in the housing if a place is provided, or directly in the supply pipe.

1. Provide protection against freezing. Mount an electrician and the necessary automation.

1. Connect incoming and outlet ducts. The case is closed. If necessary (installation in the attic), the recuperator is insulated outside or enclosed in a heat -insulating casing.

Why in an apartment with central heating an air recuperator

The heat exchanger-regenerator, also known as a recuperator as it is commonly known, is a small supply and exhaust system intended to reduce the amount of heat generated in the space.

Many of our countrymen focus especially on the final phrase, "saving on heating," even though a heat exchanger-regenerator in a contemporary city apartment is essentially a small supply and exhaust installation—an additional tool for enhancing or generating ventilation in the space.

Natural ventilation is nearly impossible in apartments with metal-plastic windows and high-grade sealed doors, which are found in 80% of city apartments today. Installing a recuperator allows for air exchange and adds oxygen to the home’s air mixture in an apartment with central heating.

The installation of a heat exchanger has both an economic impact and a heat exchanger-regulator. The airtight city apartment lacks natural ventilation, and as you are aware, extract cannot exist in the absence of inflow. Systems for forced supply and exhaust ventilation are installed to provide air exchange within the building. During the winter, the supply air needs to be heated, which is typically accomplished by electric heaters. Air conditioners are installed in summertime to lower the indoor temperature.

Air conditioners and refrigerators are two fairly energy-intensive appliances. Additionally, since heat energy meters are not yet widely available in our nation, we must pay for each kilowatt of electricity used, which is measured by our own electricity meters. Without the need of energy-intensive modules, the recuperator performs the same functions, warming the supply air in the winter and cooling it in the summer. The standard "kopeck piece" can have its air completely changed once every two hours with the installation of just one such device. Pi, plant pollen, street dust, and other debris will be removed from the air entering the home.

How to assemble a tubular recuperator

This kind of heat exchanger has a very simple design. A tubular recuperator is even simpler to construct than a plate one. You’ll need to buy the following supplies to assemble it:

• a piece of plastic sewer pipe 160 mm;
• two bias-ceremiers per 100 mm;
• Aluminum corrugation for 100 mm.

The longer the completed device, the more effective it will be in the air recovery, so keep that in mind when purchasing materials. This type of heat exchanger’s assembly looks like this:

1. Corpushes are packaged inside the pipe. It should be completely stretched out.
2. Blums are put on both ends.
3. Corporal is hermetically tightly attached to one of their exits from both sides.

The tubular river is connected to the diverting duct, allowing the flow to go through the corrugation. Excellent repair for free exit adapters. Consequently, the flow that passes through it will move along the pipe, absorbing the heat from the corrugated walls.

Recuperators are incredibly helpful tools that should be added to the ventilation system. Furthermore, as you can see, autonomously assembling the most basic models of this kind of equipment is a very satisfying task. You can save a lot of money on heating if you create this design by hand.

Calculation of the recuperator

Q is equal to 0.335x lx (tcon. – tbeginning.).

• Qproductivity (meters cube. per second).
• L is the amount of supply air, which should enter the norms for a person (60 m3 per hour for the one who is constantly in the room, and 20 m3 for a temporary visitor.).

The temperature differential between the street temperature and the desired temperature is indicated in brackets.

For instance, a room requiring 120 m3 of air per hour needs to have its air heated by 20 °C.

Q equals 800 watts (0.335 x 120 x 20).

How to find out the efficiency of a ready -made recuperator

In order to accomplish this, you must eliminate the air temperature sensors at three entry points:

• Coming from the street to recovery (t_Celebration.)
• Incoming stream into the house, after recovery (t_river.)
• A stream leaving the house to recovery (t_house.)

100% is multiplied by the outcome.

For instance:

In the recovery stream, +14 °C, homes +22 °C, and the street, +3 °C.

Productivity equals (14 – 3): (22 – 3)

Productivity = 11/19 = 0.57

Therefore, this device’s efficiency under these circumstances is 57%.

Different conditions will result in different efficiency indicators for the same unit.

Types of structures

Rotating recuperator and his work plan

The recuperator’s structural design consists of a rectangular, square, or round block with holes on both sides for the supply and exhaust ventilation canals to enter.

The recuperator is classified into the following types based on the block’s design and its component parts:

• Rotary – a device with a rotating rotor in a stainless or galvanized steel housing. Rotation of the rotor around the horizontal axis occurs due to the supply of power supply. The working elements are aluminum corrugated ribbons wound on a special shaft. During rotation, the plates are in contact with the warm and cold stream of air mass. Efficiency of the rotary recuperator – up to 85%. One of the main disadvantages of the device is the large size and the presence of moving elements that wear out and require periodic replacement. Dyal device for air recovery with working elements in the form of plates
• Plate – the most popular type of recuperators . Consists of thin panels, connected and neatly laid on each other with a small ventilation gap. Metal panels are heated due to warm air, which passes through the device. The panels by heat transfer transmit the accumulated energy to the cold flow. Efficiency of the device – 40–65%. Differ in high reliability and the ability to work without electricity costs. Recuperator with a design of steel tubes
• Tubular – a device consisting of metal tubes with a diameter of up to 10 mm, combined into a cylindrical duct. According to the principle of operation, similar to a plate river . Heated spent air passes through the tubes, giving part of thermal energy, and cold air, moving in the space between the tubes, takes part of the heat. Due to the simple design, the recuperator has high reliability and takes up little space. Recirculation water recuperator for ventilation in public places
• Recirculation water – a device with an intermediate heat exchanger in the form of a liquid. Usually used distilled water or antifreeze. Unlike other types, the circulation recuperator has a more complex design . The liquid circulates through the channels between the exhaust and supply channel due to the pumping pump. Right operator"s efficiency – up to 65%.

Large-scale public spaces employ roof air flow recuperators, which are integrated into the current ventilation system. The roof recuperator’s efficiency doesn’t go above 65–68%, but its compact size and great dependability make it perfect for use in crowded spaces. It is not appropriate for work in an apartment or residential building.

Video: What is air recovery

According to the norms

Air exchange rate per person: at least 30 m3/h, but not less than 0.35 1/h. If we take away the portion of the summer premises that is smaller than 20 m2/person, the overall area of the apartment is 3 m3/m2.

The entire area of the apartment, minus the area of the summer premises, should be used to calculate the air consumption, expressed in m3/h, based on the frequency of the premises. Mechanical hoods and fireplaces need additional air flow in apartments with airtight fencing structures.

Basically, I made the decision to split the house in two, starting with the second floor’s ventilation. I spend a lot of time in the bedrooms, office, and nursery—there’salsothe primary source of pollution.

90 to 150 cubic meters of air are required for three people, depending on the amount of CO2 present in the streets.

I will use 0.34W x 90 m3 x (22g-(-3 g)) x 24h x 213 days = 3910kVTH annually if I serve only 90–150 cubic meters and warm them up to a comfortable 22 degrees. (at the average temperature of the heating period -3 g.) According to my electricity tariff, this will come to 4.54 x 3910 = 17,751 rubles annually. This is a significant amount considering that I pay roughly 65 tons for all of the electricity I use for heating, lighting, life, technology, DHW, etc. each year. R.

It was decided to install a recuperator because, of course, it is not reasonable to do the supply ventilation.

I won’t go into detail about each recuperator type’s design or draw comparisons between them because there are so many variations. In my opinion, the exhaust ventilation supply needs to meet the following requirements.

1. as little as possible and easier for maintenance
2. Do not significantly affect the load of the network, that is, without a warm
3. She should not be heard, t.To. The influx goes to the bedrooms, I don’t want noise at all (the laptop fan is loud and unpleasant for me)
4. Cheap and simple

The decision was made to install the entire system in the house’s small attic. However, since the installation case is cold, the air ducts need to be well-insulated.

The principles of the work of the recuperator

Depending on its type, the recuperator’s operating principle varies. Of course, each of the categories of structures on the list has unique properties when it comes to operation. We list the most typical.

Plastic recuperator

This species is an example of a sheet metal monolithic cassette. Such a cassette allows air to flow through unique channels that are either laid by an intermediate seal or stamped on sheets. In a recuperator like this, streams are not mixed. The plates are heated by one stream while cooling by another, which allows for the heat exchange process to occur. Plastic recuperators are the most popular kind of thermal barrier for homes because of their many benefits.

The lamellar recoverer’s primary characteristics are:

1. low price;
2. structural elementary;
3. compactness;
4. Ease of maintenance;
5. Ease of cleaning (if the cassette is versed)
6. accessibility of materials for manufacture;
7. Lack of mechanisms.

Without sacrificing efficiency, collapsible recuperators can supply the purest incoming air possible while the device is operating.

It is always important to keep in mind the dew points and the fact that condensation forms while these heat exchangers are operating. The plate block of the reimvator may experience frostbite and lose airflow at negative air flux temperatures.

Because of its straightforward design, the recuperator is most frequently seen as a transplanted. Its efficacy can be characterized as "average type," with some sources claiming an efficiency of up to 60%.

Rotor recuperator

A short length of pipe filled with corrugated steel plates runs the length of the heat-impedential in this type of device. The tidal axis is used to guide the installation of the rotating mechanism. The rotor passes through cold air after passing through heated internal air first. To keep the interior air temperature constant, the plates alternate between heating and cooling. It is acknowledged that this kind of recuperator is the most efficient. Experts acknowledge that the device’s bulkiness is a drawback, but the design feature prevents it from being compact.

Thermal utilizer with intermediate coolant

These recuperators work with liquid heat exchangers, which run on a solution of ethylene glycol (effective coolant). The tidal and exhaust sections are split and divorced at a specific distance in these users. You can use these devices in an environment where the inflow and outflow of fluids cannot be mixed thanks to this feature. The coolant moves either by pumping or naturally. A fine tune of the coolant flow according to the project is required to boost the efficiency of such a heat utilizer.

Tubular air -exchanged mechanism

Two individually entwined copper or aluminum pipes and boxes are needed to construct the device. The length of the pipes and the density of their fit together have an impact on the final product’s quality. The tube structures positioned in the channels allow the unit to function. The beams of welded thin-walled tubes, along which air circulates, are used in heat exchange operations.

The smaller pipe allows room temperature air to flow through it, heating the metal. For the garage, the "Pipe in the pipe" mechanism will be a fantastic substitute for factory goods.

You will need to lengthen the pipe in order to increase efficiency, which will impact the structure’s weight.

Maintaining a cozy and healthful living space in an apartment requires proper air heating and ventilation systems. Stale air, moisture, and pollutants can be eliminated with the aid of proper ventilation, and during the winter, warmth is guaranteed by effective heating.

A vital factor in efficient ventilation is maintaining an even distribution of airflow throughout the apartment. Combining mechanical ventilation systems, such as air purifiers and HVAC systems, with natural ventilation techniques, like opening windows and using exhaust fans in bathrooms and kitchens, can accomplish this. You can avoid problems like indoor air pollution and mold growth by keeping a balanced airflow.

Energy-efficient heating systems have the potential to significantly improve comfort levels while also saving money. Energy-saving solutions that help maintain a constant temperature include radiant heating, programmable thermostats, and upgraded insulation. Furthermore, adequate insulation in the attic, floors, and walls can stop heat loss and keep the apartment warm without using too much energy on the heating system.

It’s also critical to take into account how natural light affects ventilation and heating. In addition to adding natural warmth, sunlight enhances indoor air quality by assisting in the destruction of bacteria and mold spores. Energy efficiency can be further improved by maximizing natural light through well-placed windows and skylights, which can minimize the need for artificial lighting and heating.

In summary, efficient heating and ventilation are necessary components of a livable and healthy apartment. Through the use of energy-efficient heating systems, ventilation techniques, adequate insulation, and optimizing natural light, building occupants can experience year-round comfort, enhanced indoor air quality, and reduced energy consumption.
