How to make local supply ventilation of the apartment and private house

To keep your house comfortable and healthy, you must make sure that there is enough ventilation. A buildup of indoor air pollutants, an abundance of moisture, and even the growth of mold can result from poor ventilation. Installing a local supply ventilation system is one practical approach to enhance ventilation. We’ll discuss what local supply ventilation is in this article and how to install it in homes and apartments.

Introducing fresh air directly into particular rooms of your house, like bedrooms, living rooms, or kitchens, is known as local supply ventilation. Local supply ventilation targets particular areas where occupants spend the majority of their time, as opposed to central ventilation systems that distribute air throughout the entire house. Better control over indoor air quality and more effective airflow are made possible by this method.

The ability of local supply ventilation to deliver targeted ventilation where it is most needed is one of its main advantages. For instance, a local supply ventilation system can swiftly remove pollutants and excess humidity in a kitchen, where cooking activities produce a lot of heat and moisture, assisting in the maintenance of a hygienic and comfortable atmosphere. Similar to this, adequate ventilation in bedrooms can enhance both general health and quality of sleep.

Putting in a local supply ventilation system doesn’t have to be costly or difficult. To attain efficient ventilation, you can employ a number of tactics. For example, adding trickle or window vents minimizes heat loss while letting in fresh air. Exhaust fans and supply vents can be used together to provide a well-balanced airflow throughout the house.

Whether you live in a private home or an apartment, maximizing ventilation is essential to establishing a comfortable and healthy living space. Gaining a better understanding of local supply ventilation principles and putting them into practice will help you and your family enjoy better indoor air quality and overall well-being.

Step	Description
1	Assess the ventilation needs of your space, considering factors like room size and occupancy.
2	Choose the type of local supply ventilation system suitable for your home, such as continuous or intermittent ventilation.
3	Select the appropriate location for the ventilation unit, typically near the ceiling for optimal air circulation.
4	Install the ventilation unit according to manufacturer instructions, ensuring proper sealing and secure mounting.
5	Connect the ventilation unit to an external air supply, such as through a duct leading to the outside.
6	Test the ventilation system to ensure it is functioning correctly, adjusting settings as needed for optimal airflow.

In this article, we"ll delve into the importance and practicality of implementing local supply ventilation in both apartments and private houses. Local supply ventilation is a crucial aspect of maintaining indoor air quality and ensuring a healthy living environment for occupants. By introducing fresh air directly into specific rooms or areas, this ventilation system effectively replaces stale air, reduces pollutants, and controls moisture levels. Whether it"s combating kitchen odors, managing humidity in bathrooms, or enhancing overall air circulation, local supply ventilation offers tailored solutions to address the unique needs of different spaces within a home. From simple window vents to more advanced ducted systems with adjustable airflow, there are various options to suit different preferences and budgets. By understanding the benefits and exploring available technologies, homeowners can make informed decisions to improve the air quality and comfort of their living spaces through local supply ventilation.

Options for organizing an influx

We’ll use an example to demonstrate the significance of supply ventilation. Imagine a pump pushing water out of a sealed container. There is less air in the released volume, so the tank’s pressure decreases. When the pump’s power runs out and it is unable to overcome the vacuum, the working wheel will start to mix the water in place.

Key moment. A similar principle applies to air exchange indoors: in the absence of an inflow, contaminated air cannot be effectively removed by forced or natural extract.

The flow of air masses outside is excluded after installing hermetic plastic windows and laying the supply gap that was previously under the windowsill. Consequences: An unpleasant odor enters the apartment through a smaller mine (the toilet), which is overturned by a fan or higher section (usually in the kitchen). The ventilation in the living room, bedroom, and other rooms is not provided.

A private residence can be fully equipped with supply and exhaust ventilation in a number of ways:

• The folk method is cutting of window seals;
• buy air conditioning with street air supply;
• Introduce an adjustable air valve into the plastic window;
• make a hole in the wall and mount the local supply device.

Suggestions. The following methods can be used to assess a natural home hood’s performance: Take off the kitchen and bathroom ventilation grilles, place two to three paper strips over the openings in the first two to three strips, stack the second sheet with an A4 sheet, and tape. The thrust operates if the strips are drawn into the canal, which allows air to enter the apartment.

Examine the benefits and drawbacks of each of these approaches. Our job is to provide you with an appropriate and reasonably priced method of organizing the incoming data.

The simplest free method

Utilizing the window profile’s built-in drainage holes to remove condensate outside is the fundamental component of the method. The weekend is situated on the outside of the profile and is covered in plugs, as seen in the picture. There are two concealed holes where the water goes on the inside of the frame.

One requirement is that there must be good traction in the vertical channel for the method to function. Begin by cleaning the ventilation shaft and inspecting the hood.

The concept of home masters enables you to quickly and affordably arrange the supply ventilation on your own:

1. Open the window sash, remove the mosquito net.
2. Using a screwdriver, pull out both plastic plugs from external drainage holes.
3. Carefully cut a section of the rubber seal on the upper end of the frame with a knife with a knife no more than 5 cm long. Close the window.

The way this ventilation works is as follows: the outside air is drawn in by the ventilation thrust, travels through the drainage hole, enters the profile, and exits through the space between the sash and the frame. The air stream rises to the upper portion and then enters the room through the seal’s opening.

When the air is combined with the ascending convective stream from the heating radiator at the output, the winter cold inflow is heated. This process starts at the window’s design. Similar to this, a plastic balcony door’s supply gap is created by further cutting the outer gum, as demonstrated in the video:

This option has the benefit of being completely free and offering a genuine way to arrange for the apartment to be ventilated with the window closed. There are numerous additional drawbacks:

• The air flow cannot be adjusted, the strong wind will become blown through the gap;
• In the summer, unfriendly insects, for example, wasp can settle in open drainage;
• In the warm period, when natural traction decreases due to a small temperature difference, small holes will not miss the right amount of air.

The final drawback is that only the opening sash windows allow for the removal of a portion of the rubber seal. Diffuse windows cannot be drilled. As a result, the approach cannot be deemed appropriate and advocated for by all homeowners.

Split systems with ventilation function

Numerous manufacturers’ home air conditioners have features beyond just heating and cooling; they can even bring in outside air and function as an extractor (or use a tributary). Then, this is a practical option:

• Air renewal in the room is forcibly, regardless of traction in the mine;
• The air drawn by the fan is processed – filtration and heating or cooling;
• The flow intensity is regulated;
• The volume of the influx does not depend on gusts of wind and other weather conditions.

Citation. A different fan, housed in the split system’s inner block, absorbs the air mixture. An additional tube, a 1-meter-long air duct, is installed through the outer wall.

The primary obstacle to the adoption of this kind of air exchange is the expensive equipment. Purchase air conditioning units for 500–600 per room, e.g., for supply ventilation—this is inappropriate, as there are less expensive options. However, if you intend to install a split system for cooling, you ought to consider selecting an aggregate that features air recirculation and an inflow.

The following are the drawbacks of utilizing the air conditioner as a supply installation, which we deduced from online store and forum reviews:

1. The influx is carried out only with the unit turned on, the rest of the time the outer channel is covered with a barrier.
2. A separate fan responsible for feeding a fresh air mixture is constantly noisy.
3. Due to quick pollution, the filters will have to be cleaned more often.
4. On some models, ventilation and air conditioning modes are incompatible. The supply and heating of the air is turned on separately.

Note: Correct installation of a split system in a private home or apartment will provide you with a comprehensive how-to.

Installation of the supply valve in the window

The so-called window venturer is a plastic lid that is oblong and has an adjustable damper. Two varieties of valves exist:

1. Muffled. In the profile, a through supply gap is milling, a protective visor is screwed outside, from the inside – a cover with a stream regulator.
2. Opening wings. Installed on the inside of the frame, part of the sealing rubber changes to a special material. Cleep the window is not required.

Citation. Valves are designed to work with any kind of transparent structure, including PVC, aluminum, and wooden ones. They enable you to control the supply and exhaust systems with natural motivation. Priced up to ten e, popular brands include Ventts, Air-Box, and Aereco.

In rooms with a decent hood, supply window devices are recommended; otherwise, the air flow will be insufficient. The stated valve performance of 30 m³/h is sufficient for one person, but insufficient for typical living room ventilation.

It is simpler to cut the laundry on the doorbell in the boiler room and bathroom, where regulations call for a more intense air exchange. Three to four of these products will be required. Another nuance: the declared productivity of the devices is significantly different from their actual productivity.

Calculating the influx is simple: use our instructions to measure the input slit’s diameter and the amount of air that passes through it. I’ll tell you what happened: the output will be less than the 30 m³/h that was promised (maximum 25 cubic meters at 1 m/s). It is absurd to require four valves in each room for three family members.

How to mount the sash’s supply valve:

1. Attach the product body to the upper end of the open frame at the mounting site.
2. Focusing on the edges of the lid, cut the standard seal, for Air-box the length of the removed site will be 35 cm. A similar piece of rubber must be cut on the main frame, opposite the sash.
3. Insert 3 plastic dowels into the groove of the window profile – the latch, trying on the fasteners on the lid. Remove the protective tape from the case and fasten the valve with self -tapping screws.
4. Instead of a cut seal, glue the elements from the kit of the ventilation device.

Installing a valve in a deaf frame is more challenging because you have to carefully cut a small opening in the profile. Make the gap yourself by applying the precise marking and drilling holes if you don’t want to get in touch with the masters and pay them money. There are no issues with the visor or the inner cover. In the video, there are brief instructions for installing the product for the sash:

Window ventilators are generally suitable for small apartments. However, in the high-ceilinged rooms of a suburban cottage, the stated performance is insufficient. The second drawback is that there is usually nowhere for the valve to be located beneath the PVC window frame, which partially overlaps with the upper slope. Next, a different technical fix was identified as..

Wall ventilation device

The components of the wall-mounted passive ventilation valve are as follows:

• the supply pipe with a diameter of 60-150 mm (the size depends on the model and productivity of the device);
• The outer end of the pipe is closed with a mosquito net and a ventilation grill;
• An adjusting damper is built from another end;
• From the side of the room, the pipe is connected to the body where the air filter (G3 cleaning class) and the heat -insulating gasket are placed.

Note: An insulation layer is placed between the wall and the pipe to prevent condensation from forming inside the channel.

Similar to the preceding instance, exhaust mines or fans create a vacuum that guarantees the influx through the valve. Depending on the user settings, 35–60 m3/h of air can enter the room with products. The influx flow rate will also rise to 70–90 m³/h when the local hood—for example, the kitchen—is turned on mechanically.

There are two types of performance regulators found in devices made by different brands: diaphragm and petal. The latter is more affordable. Any damper can be fully closed if needed. Products from well-known manufacturers like Ventts, Domovent, Helios, and others start at $15.

How to install the valve:

1. Determine the location of the ventilation element. The recommendation is as follows: Low performance devices with a pipe Ø60 mm are best put between the windowsill and the heating battery. Place valves with a diameter of more than 10 cm next to a window opening at a height of 2 m from the floor.
2. Make a through hole in the wall using a construction perforator and a set of drilling stamps. In a frame or wooden house, use crown drill. If the room borders on the balcony, it is better to drill outside.
3. Cut the pipe according to the thickness of the fence, wrap it with a foam insulation and insert tightly into the hole. The remaining cracks blow out with mounting foam.
4. Attach the valve body to the wall from the inside, connecting to the pipe. Put a ventilation grill outside.

Suggestions. Try to make the hole as round as you can, paying particular attention to the insulated channel’s outer diameter. Because the "Ventts" company’s products have telescopic sliding pipes, they won’t need to be cut off. View the installation’s specifics in the video:

Passive influx devices can be used for much more than just ventilation in a country cottage or apartment. Other auxiliary buildings, such as a boiler room, a garage with a basement, or a bathroom, can also have valves for air exchange.

There are just two drawbacks: manual adjustment while in use and the lack of cold air heating. The damper is fully open in the summer and minimally installed in the winter. Benefits

• The valve is suitable for most ordinary users in price and performance;
• Inclusive air is cleaned by the filter;
• The device does not freeze and is not covered with condensate, hooks appear on the heading during frost below minus 35 ° C;
• does not consume electricity, operating costs are minimal.

Brisers and recuperators

The solution to the wall valves’ characteristic cold air supply issue was found in breezers, which are local supply units furnished with an electric heating element and a fan. The unit’s benefits:

• Three steps of cleaning the influx – in a rude, thin and sorption (coal) filter;
• air heating to a set temperature;
• automatic and manual control of fan performance;
• Air quality monitoring – measurement of humidity, temperature and concentration of carbon dioxide;
• partial recirculation – the return of indoor air after filtration – allows you to save electricity;
• Remote control from the remote control or smartphone.

Three things about the unit are not so good: the electricity costs for running the unit, the high cost of a breeze, and the cost of fixing it if it breaks. There’s no need to explain the installation technology because, like the valve, it’s a household appliance that is built into the wall.

Citation. Any living space can be easily and comfortably ventilated with the aid of brisers. However, calling units in public spaces is challenging because the well-known brand "Tion" products start at 300 at. e.

Even more expensive is a wall recuperator, which is a supply and exhaust unit that can absorb the heat from the far-off air. There are three different installation types, each with a different price and working principle:

1. Reversible (sellers call them regenerative). The algorithm of the work is simple: first, the ceramic heat accumulator heats with exhaust air, then the only fan changes the direction of the flow and the element gives the accumulated warmth of the inflow. The cycle is repeated with an interval of about 1 minute.
2. Rotation. 2 fans are constantly working here – an influx and exhaust. Both streams pass through the rotating rotational recuperator, exchanging heat.
3. Crossroads. Exhaust air transfers heat to the flow through the thin walls of aluminum or copper heat exchanger. Fans direct streams towards each other, as shown in the diagram.

With a cross-exchanger, you can recover the most energy efficiently, returning roughly 70% of the thermal energy to the room. The efficiency of rotation installation is marginally lower, at roughly 5%. As is customary, vendors exaggerate these recuperators’ efficiency, and it is unknown what the true indicators of heat transfer in reverse units are.

Conclusion

Therefore, forced-action ventilation units and valves can be used to arrange full supply ventilation in apartments and private homes. Although window valves and roadways don’t provide much air, recuperators and briners are highly efficient. The apartment’s wall-mounted natural ventilation supply device is the compromise solution.

Maintaining a healthy and cozy interior atmosphere requires adequate ventilation in our homes. We have discussed the value of local supply ventilation in this article, as well as how private homes and apartments can use it.

A focused method of introducing fresh air into particular rooms of a building, like living rooms, bedrooms, or kitchens, is provided by local supply ventilation. We can enhance indoor air quality and create a more comfortable living environment by delivering fresh air directly to the areas that require it most.

Reducing reliance on conventional central ventilation systems—which can be expensive to operate and inefficient—is one of the main advantages of local supply ventilation. Local supply ventilation saves energy and resources by allowing us to concentrate on the areas that require ventilation the most, as opposed to ventilating the entire building at once.

It’s crucial to take the needs of the individual occupants as well as air quality and humidity levels into account when implementing local supply ventilation. We can maximize indoor air quality and reduce energy consumption by tailoring ventilation solutions to these needs.

Local supply ventilation has many advantages that you and your family can enjoy, regardless of whether you live in a private home or an apartment. You can benefit from lower energy bills, better comfort, and better air quality for many years to come by making an investment in a well-designed ventilation system.

Local supply ventilation appears to be a workable and efficient solution as we work to create living environments that are healthier and more sustainable. We can upgrade our houses and live better by utilizing the power of targeted ventilation.
