Ventilation in the kitchen: the principle of operation and the arrangement of the air flow, the installation of a forced and natural system

The kitchen is without a doubt the focal point of any home. It serves as a focal point for family get-togethers, discussions, and creative cooking in addition to being a place for cooking. However, in addition to the sound of pans sizzling and spices smelling, ventilation is another crucial component that is sometimes disregarded. Maintaining a healthy indoor environment, avoiding moisture buildup, and getting rid of pollutants and cooking odors all depend on proper kitchen ventilation.

Having a solid understanding of the fundamentals of kitchen ventilation is essential to designing a cozy and secure environment. Fundamentally, ventilation is the process of exchanging outdoor and indoor air to enhance the quality of the air. This procedure is especially crucial in the kitchen because cooking byproducts like steam, grease, and smoke are highly concentrated there. These pollutants can remain in the air without sufficient ventilation, which can cause discomfort and even pose health risks.

For kitchen ventilation, two primary systems are frequently utilized: forced and natural ventilation. In order to promote air movement, natural ventilation uses passive techniques like windows, vents, and exhaust fans. By utilizing the air’s natural flow, this system draws in fresh air and releases stale air. Natural ventilation can be somewhat helpful, but it might not be able to sufficiently meet the ventilation requirements of contemporary kitchens, particularly those with a lot of cooking activity or little access to outside air.

Conversely, exhaust fans and range hoods are examples of mechanical parts used by forced ventilation systems to actively remove airborne pollutants from the kitchen. These systems offer more control over airflow and can be tailored to meet the particular needs of the room. Forced ventilation solutions, whether in the form of a discrete under-cabinet fan or a sleek overhead hood, provide effective and dependable performance, guaranteeing a healthier indoor cooking and dining environment.

For best results, airflows must be arranged properly, regardless of the ventilation system selected. The purpose of airflow patterns should be to divert cooking emissions from the cooking area and to capture them at the source. In order to collect rising heat and pollutants, exhaust vents are usually placed above cooking appliances like stoves and ovens. Intake vents should also be positioned carefully to allow fresh air to enter, enhancing circulation and avoiding stagnation.

In summary, adequate kitchen ventilation is essential for both indoor air quality and safety, not just comfort. The objective is always the same, whether forced or natural ventilation is used: to create an area where cooking is enjoyed without sacrificing comfort or health. Through comprehension of ventilation principles and appropriate equipment and airflow design purchases, homeowners can guarantee that their kitchen will continue to be a hospitable and salubrious space for many years to come.

Types of exhaust systems

Due to the fact that different customer needs drive ventilation system manufacturers to design products that can best satisfy the needs of any customer, there is a wide variety of exhaust systems available in the current home appliance market. It is necessary to sort through this diversity.

Air purification methods

Air can be purified through various ventilation techniques. The hoods are separated into 2 categories based on which one is utilized in a specific product:

1. 1.
   evacuating. These devices are removed by air using a ventilation hole in the kitchen, where a corrugated pipe or metal box is connected. As a rule, the duct is equipped with a valve that does not allow the appearance of reverse traction.
2. 2. Circulation. In these products there is a coal filter. This is not an exhaust device, but a filtering installation that cleanses the air of unpleasant odors, t. To. The external flow of air from the street in this case is not provided. Such models attract the ease of installation, but cannot protect, for example, from gas leaks.

In the kitchen, circulation systems and conventional ventilation can be paired. The pricey service and high cost are among the drawbacks. Filters require routine replacement.

The evacuating exhaust system differs in that it has the ability to remove surplus heat that is continuously produced during cooking. One does not find such a function in circulation devices.

Type of design

Apart from the primary purpose, buyers focus on additional attributes of different products. Exhaust equipment must be easy to use and harmoniously integrate into the room’s design. You should be able to mount it yourself as well.

Contemporary gadgets vary in terms of performance, installation technique, manufacturing material, design, and additional features.

Hoods fall into two categories based on their designs:

1. 1. Domed. The product is called due to the shape of the air intake, which resembles a dome. An air duct that removes air through the ventilation channel comes out from the opening.
2. 2. Built -in. Such models can be hidden from prying eyes, hiding the hood in the kitchen set. Often built -in hoods have a retractable panel. This makes it possible to economically distribute the space and ensure convenient device management.

You should arrange the space so that kitchen appliances and furniture work well together and are easy to use before placing an order for a headset and selecting an exhaust device.

At the installation site

The kitchen’s size, the slab’s location, and the headset are all taken into consideration when mounting the hood.

Exhaust structures vary depending on the installation. They are:

1. 1. Corner. Installing the stove in the corner saves space and makes the hob that is affordable. The design directly has the shape of the dome.
2. 2. Nasty. In this case, one part of the hood adjacent to the wall, and the other is located above the stove.
3. 3. Island. This hood is installed above the stove, which is located in the center of the kitchen.

You need to read the instructions very carefully before doing the installation yourself. Every model has installation features, but all products follow some universal guidelines. This represents the furnaces’ height above the ground. It should be at least 80 cm for gas plates and at least 70 cm for electric plates.

Installation of built -in hood in a closet

In the custom closet, the built-in hood is nearly invisible. It is fastened precisely as previously mentioned; the screws only screw into the walls. The duct needs to have holes made beneath it, but only in the upper shelves. Since the location of the air output varies depending on the manufacturer and model, this is done after the hood is purchased.

An illustration of how to install a built-in hood

If the locker hangs, it is better to remove it. In the removed cabinet, install the hood in place, mark the location of the air output on the lower shelf, cut it out. For this it is easier to use an electrician and a saw with small teeth. Limit saw almost no chips. If desired, you can close the cut place with a plastic C-shaped furniture profile. They are hard and flexible. Flexible to use simply – it bends at any angle, the hard before installation will have to be warmed up with a construction hairdryer. These profiles are “planted” on glue, most often they use “liquid nails”. After installation in place, remove the remains of the glue (with a damp clean rag), fixed with painting tape to the shelf. Cut the excess profile with a file with a small tooth, clean the cut with sandpaper with fine grain.

The process of getting a cabinet ready for the hood installation

We puncture other shelves in the same manner. By the way, depending on the chosen section of the air duct, they may already be rectangular rather than round.

Subsequently, every shelf is positioned accurately, and the cabinet is fixed and hung. It is screwed to the extract with built-in attachments through the body holes. The process of attaching the air duct comes next.

The duct from the hood and the lattice with the check valve

Initially, a plastic pipe (such as D-125mm) is used in place of the corrugation, and it is brought to the hole by passing it through one or more knees. In this instance, a specific division is made in the ceiling hole itself.

A small rectangle is left through the grate with the valve to allow for a natural influx, and the entry beneath the pipe is mounted on top.

Additionally, the grate ought to be positioned below rather than above. If not, the hood’s air flow will be forced upward, raising the so-called check valve.

Naturally, though, you can safely place from above, side, or below if your valve design is more sophisticated and includes a circle or rectangle with an displaced axis rather than just simple polyethylene stripes or a whole partition.

In actuality, though, the entire design frequently fails to function as intended. A tiny amount of dust still finds its way into your kitchen through tiny cracks and micro-fame when the exhaust unit is turned on and pressure is applied. The dust then settles on the dining table.

There is no 100% saving check valve. Naturally, most of the air escapes, but it is a fact that dust gradually begins to accumulate inside the apartment.

Furthermore, natural ventilation through small sieves will be significantly worse when the hood is turned off because the diameter of the original hole has shrunk.

You are far more capable in every aspect.

The schematic diagram of the kitchen hood

Any hood’s composition consists of the following components:

• Fan with an electric motor. A multi -speed asynchronous engine provides a rotation of the exhaust fan, due to which air flows pass through filters that delay fat.
• Filters. All hoods are equipped with fat -based filters of reusable or disposable use. Coal filters are present only in circulation models and act similarly to activated coal. Their replacement is performed once every 3-4 months of operation.
• Lighting lamps. Lighting the hob is performed using incandescent lamps, LED or halogen lighting devices.
• Switching scheme. In different models, speed switching is carried out in various ways: using sensory devices, by means of buttons or using a slider switch.

Examine the typical electric shock, which includes every component listed above. All of the major components that we listed above are included in the typical electrical circuit for the kitchen, along with instructions on how to connect them.

How to hang an hood above the stove

The distance between the gas and electric plate and the hood

A well-chosen hood should have a width that is either slightly wider than the plate or equal to it. An exhaust system needs to be fixed in addition to being placed in order to be installed. It ought to be situated precisely above the plate’s surface.

Note: The specifics regarding the hood’s installation heights are directly related to the type of hob. If your stove is gas, the height difference between the hob and the hood should be 75 cm; if the plate is electric, it should be at least 65 cm. Thus, different distances must be taken into consideration in order to hang the hood over the gas stove and electric plate.

Selecting the height of the hood prior to installation should be done by considering a housewife’s growth indicators. The lower edge of the exhaust system should be just above a woman’s head if she stands up straight. Installing below this indicator is not advised. It won’t be a problem if you install above.

Well informed! In order to properly install the hood over your gas stove, you need to be aware of the following detail: you will need to purchase a hood with greater power if the system needs to be installed higher than 90 cm from the hob.

Now let’s discuss the subject of "mount for modern hoods." Depending on the type of exhaust system, the fasteners vary:

1. The built -in kitchen hood should be attached to the surface of a specially designed cabinet for this.
2. The hinged system (flat) and dome (fireplace) hood is attached to the surface of the wall.
3. The island hood is attached to the surface of the ceiling: when buying, in the kit, a clear installation instruction is always given, and the entire suspension system.

Features of installation of various systems

Kitchen hoods are categorized based on the principle of air purification as follows:

• Propective, ensuring forced cleaning of contaminated air and its removal to the ventilation system of the house or on the street.
• Circulation, clean the air indoors through coal filters inside the case and do not require ventilation access. It is easier to install such an extract, but it is less effective than running. The main tasks of installation are to fix the design itself as reliable as possible and decide how to connect an hood in the kitchen to an electric outlet.

The hoods are separated into multiple categories based on the type of fastening:

1. Suspended. More often, these are flat hoods that are not connected to the air duct. Are attached to the lower part of the cabinet using the fasteners available in the kit. To access the openings for fastening, it is necessary to remove the hood filters. First, marking is made, with a pencil, points for holes are planned. Then the drilling is carried out, the level and connection of the elements is checked. Connection of the hood is to include it in the outlet.
2. Wall. Have a diverse body design. The fastening provides for the device of a frame made of a metal corner, which will become a support for the case. The frame is attached to the wall with dowels. In the event that a gas pipe interferes, the mount should be made using long self-tapping screws. They have a thread with a nut at one end, the other screws into the wall. The hood body is screwed to the stiletock using a nut at the required distance from the wall. If the length of the screw is not enough, wooden bars are used to increase.
3. Built -in. Organically fit into the interior, since their main part is located inside a hinged cabinet or shelf. The installation of a built -in hood begins with fitting, which is more convenient on a hanging cabinet. The installed case is placed in a closet above the stove. Distributions for marking, level and central. If all the necessary parameters are given to the norm, make the marking of the holes for fastening. Then the kitchen cabinet is removed from the wall and cut through the necessary holes in the lower part and shelves, depending on whether the conclusion is required into the ventilation system. First, the holes are made with a drill inside the marking circuit, and then cut the profile with a jigsaw.
4. Island hoods. These are modern hoods in the kitchen, attached to the ceiling in any part of the room. In this case, it is important to determine the type of device. If there is no way to stretch the duct into the ventilation shaft, use a circulation flat hood, which is decorated with a decorative dome.

When installing an air duct in the kitchen, think about how to install a hood correctly.

In the home, two varieties are utilized: 1. Plastic; 2. Corrugated metal (aluminum).

Plastic air ducts don’t impede airflow and have a smooth surface. Although they are more expensive and require more assembly than corrugation, they have a nicer appearance and don’t need an extra box.

Operation safety

Since the hood set has a fan, the appliance needs to be plugged into an outlet. Should the apartment repair be new, a separate exhaust device socket will be required. It can be hidden behind kitchen furniture components since it only needs to be used with one device. Nonetheless, you also have to make it easily accessible. Another guideline states that the outlet and sink should be separated by no more than 50 centimeters.

In the kitchen, there is a constant combination of heat and humidity. Cooking fat and excessive moisture build up on the fan latch, which provides the ideal environment for an electric circuit to occur. For this reason, a cable with three cores must be used to connect the device to the power grid.

Phase, zero, and "Earth" should all be present in the electrical wiring. The grounding wire features a green longitudinal strip and yellow insulation. All new construction comes with euro-zoots that are already grounded; all you have to do is connect the grounding cable to the Stepsel terminal. The three distinct lines that make up the icon make it extremely easy to determine.

Older buildings do not have any grounding. In this situation, you must arrange protection on your own. The machine on the shield will shut off if there is an electric breakdown. Additionally, potentials must be balanced.

Stages of installation and types of kitchen hoods

There are two primary categories for all of the kitchen’s forced ventilation units.

1. Open hoods, visible completely. An open hood is installed between the cabinets
2. Built into the cabinet, half -shredded. The built -in hoods are visible only the lower part

There is a location-based classification for open devices as well. These hoods can be island-shaped, wall-shaped, or corner-shaped.

The following is the classification based on the control method:

• distance (with a remote control);
• button or sensory.

The choice of equipment

The components of the hood

• Dome above the stove that sucks out the exhaust air. It is attached to one or two walls. Island models hang on the ceiling.
• Duct – a pipe made of plastic or corrugated aluminum. Its structure is carefully thought out before connecting the hood to ventilation in the kitchen.

Types of devices on the principle of operation of the system

• Recirculation – air is cleaned in a filter located inside the case, and is supplied back to the room.
• Running – they are connected to a riser or a wall valve. A filter is built into the case above the blades. It is needed so that the pipe does not clog with fat deposits.
• Combined – both principles of action are combined in them.

We’ll think about the first choice.

The design of the domes

Their form and mechanism are different.

• Cone or pyramid – installed between cabinets or in a spacious high niche.
• Hidden system – placed at the bottom of the hinged cabinet. The control panel is put to the facade. The space behind him is taken by the. The upper part where the narrowing is often equipped with shelves.
• Sliding – can rise and fall. Usually she is hidden behind the facade.
• Design in the form of an inverted letter "T".
• Ceiling model in the form of a parallelepiped – used for kitchen islands.

The lower section’s dimensions should be a few centimeters bigger than the stove’s. The range of the working height is 65 to 75 cm. Consider a height of up to 85 cm for gas plates.

The durability of the dome is unaffected by its material. The ease of maintenance makes all the difference. An aluminum building requires less maintenance than other types. Using a damp sponge makes cleaning up dirt simple. It penetrates plastic more deeply. Steel gets dirty easily. Hardened glass requires a specific cleaning solution to be wiped.

Performance determines the equipment choice. The air will be cleaned more quickly the higher it is. It is best to avoid mounting models with strong electric engines in small spaces because they require a lot of energy and space.

The choice of eyeliner

• Aluminum corrugation – is distinguished by flexibility that allows you to make turns in the right places. The ribbed surface retains the flow and quickly accumulates dirt deposits. It is very difficult to clean it. The metal resonates well and enhances the noise when working.
• PVC pipes – they consist of several straight and rotary elements fastened with glue and clamps with screw clamps. Round cross -sections have higher conductivity. The average diameter is 12.5 cm. Rectangular details help save space. Standard dimensions – 20.4×6 cm.

How to install an hood in the kitchen correctly

Many homes and apartments have the hood placed above the range in the kitchen. Its objective is to stop dangerous substances and a pair that are created in the kitchen and other areas during cooking. The ventilation shaft is used to extract contaminated air and all dangerous materials that are caught by the hood.

But few people are aware that certain guidelines must be followed when installing the hood.

As a result, the hood umbrella needs to be situated a specific height above the ground. This gap must be at least 55 cm for gas hobs and at least 35 cm for electric stoves.

It is important to keep in mind that the integrated filter in an autonomous hood that isn’t connected to the ventilation system can guarantee that only aerosol pollutants are retained. The hood filter is unable to neutralize carbon monoxide or prevent gas leaks from the cylinder or gas line.

Consequently, the kitchen hood should always be installed correctly by connecting it to the ventilation shaft. If not, it won’t be able to eliminate the dangerous chemical compounds that arise from stovetop cooking.

Working with a ventilation hole

Since a centralized ventilation system is often designed with a mine in the middle of apartment buildings, if they are randomly searching for a channel, you will need to break through the wall nearly entirely. As a result, it’s critical to understand more useful, practical, and secure techniques for locating a wall drop opening. The majority of the time, the mine either goes through a thick wall or through a wall where there is an explanation that makes sense. You should read technical documentation and speak with the occupants of nearby apartments before tapping, drilling, or breaking any walls.

They frequently inquire as to whether the kitchen’s ventilation hole can be made smaller. The truth is that it appears to take up too much space to many. This occasionally happens because a smaller grille must be used (it can be challenging to find a design that works well). The experts’ response is not surprising: they state that reducing the structure’s size in one dimension is acceptable as long as the section as a whole stays the same. The only exception will be if a smaller channel can be used to obtain the estimated amount of air.

Installation

The instructions that are attached provide a detailed description of how to install the ventilation hood. Install equipment at the proper height, in particular, and don’t disregard any of its features. Steam and fats are absorbed by the recirculation hood’s filter. Additionally, the centrifugal fan displays the unsuccessful gas in the vertical channel. An alternative fan type called axial is utilized in low-cost hoods. These fans are less expensive and operate efficiently with a short horizontal delus.

• If we connect the hood to the vertical channel, delete the check valve available in it. With a horizontal channel, we leave the valve or put in addition to its absence.
• The exit from the hood along the cross section should be equal or less than the ventilation. The shape of the meaning does not have: you can dock round and rectangular pipes.
• The pipe from the unit should not interfere with the normal operation of the usual hood.

The pipe from the hood is brought into the standard ventilation hole, which is pierced in the wall and leads to the vertical mine, not the one used for natural air exchange. Because natural ventilation will be disrupted if the pipe is installed in the typical entrance. This image displays the incorrect connection option. In this instance, the room lacks natural exchange, causing dangerous gases to build up at the ceiling.

Recommendations for connecting via an adapter are available. It has two holes in it: one connects to the pipe, and the other opens into the room. Although it would seem to be the best idea, the air is returning to the kitchen, so it is not really working. He finds it simpler to go back a short distance than to get past opposition. It is also unacceptable that the supply and exhaust channel section decreases. Although they are widely available, adapters are useless.

We adhere to two requirements in order for both ventilation systems to function jointly and accurately:

• During forced ventilation, the second entrance is blocked so that the air does not go into the room;
• The cross section of the grate covering the input of the ventilation should not be less than that of the vertical channel.

By installing the check valve and expanding the lattice’s area, we are able to accomplish this. It operates in this manner: it automatically opens when it is turned off and closes with the air from the hood.

We choose a material for the duct that has an adequate section, is not prone to corrosion, and has the least amount of resistance to air flow. Short sections connecting the device to the ventilation are acceptable for the use of corrugation, considering the resistance that is created. Using smooth, square- or round-shaped galvanized pipes is preferred.

The easiest way

The standard scheme is used in most apartments; the kitchen ventilation taps are made to draw in harmful fumes and carbon dioxide. Furthermore, the room is ventilated or has window cracks that allow fresh air to enter.

The gadget is typically found at the highest point, where warm couples rise upward in accordance with the laws of physics. If all goes according to plan, there is no need to worry about a tiny gas leak. What can’t be said about pairs or soot is that this kind of system isn’t the best at handling nuances like these.

As in the instructions

A connecting guide comes with the hood. The technical details of connecting to the air duct and hanging the device are explained. It’s crucial that the kitchen’s ventilation be organized, but I haven’t seen the rules for that.

A hood was hung, a fork was inserted into the outlet, and the exhaust pipe was sealed off from the kitchen’s single ventilation source. There is no ventilation when the hood is off! Its gills, which act as a valve, overlap the channel, after all. It appears that they placed a cross on it because they intended to improve air exchange.

Organization of kitchen ventilation systems in a new apartment

Nothing essentially new in the design of kitchen ventilation systems has been developed in the last twenty to thirty years. Everything is exactly as it was before: a fresh air stream replaces the contaminated air that was created by evaporation and gas combustion products. It is then assembled by air receivers and removed from the kitchen area.

Using recovery-absorbing ventilation devices is a novel way to modernize and purify the kitchen’s atmosphere while requiring less fresh air to enter the space. However, these absorbers are only occasionally utilized and are unable to completely replace the apartment’s kitchen’s ventilation system, particularly if gas appliances such as oven cabinets or plates are present.

Installation in the kitchen in a private house

Forced supply and exhaust ventilation combined with a heat recovery system is appropriate for a sturdy country home. Installed above the stove and with an output that passes through the wall and into the street, the kitchen requires a fairly powerful hood. The pipes that are left over after sewage is laid are frequently utilized as air ducts.

Another way to provide natural ventilation is to install a vertical channel beneath the ceiling. It is advised that the fan be installed in the channel if the wall hood is to be abandoned. In this instance, manually ventilating a private home’s kitchen entails the following steps:

• Preliminary check of the ventilation duct. By applying a sheet of paper to the hole, you can verify its serviceability.
• You need to insert a pipe into the channel.
• The fan is installed in the lot and is fixed with glue or anchors.
• The wire is connected to the mains to check its operation.
• The cable is laid in a plastic box, and the fan is closed with a decorative lattice.

The advice listed below will assist in finishing the task correctly:

• The air intake should be quite high under the ceiling, then the ventilation will work effectively.
• So that the round case of a standard axial fan enters the rectangular hole of the ventilation room, you need a special adapter.
• Connecting equipment to electricity is carried out from the lighting point located nearby. The current -carrying wire must be hidden in a plastic gutter.

An exhaust fan and a small supply supply combined are ideal because they will create the ideal microclimate in the kitchen.

Hidden ventilation system

The following limitations apply to kitchen ventilation in private homes with gas stoves:

• The ceiling in the room should be not lower than 2.2 meters;
• The window should be supplemented by the opening window;
• must be the presence of a vertical exhaust channel.

The lives of people and the safety of the house are at risk if such regulations for ventilation in the kitchen with a gas stove in a private residence are not properly followed. These requirements are particularly crucial for a wooden cottage that has a gas boiler or column. It is advised to use an electric stove to improve the cottage’s security.

Ventilation in the kitchen in the style of loft

With a single roof output and inclined slopes, the kitchen ventilation system in the cottage is frequently integrated with the air exchange system of all the other rooms. Aerators are additional devices that supplement this system by drawing moisture from the space beneath the roof.

What happens if aerators are not installed? At that point, you can bid the roof farewell because moisture will cause it to collapse very soon!

When designing a house, it makes sense to consider installing a ventilation system. Nonetheless, it is feasible to upgrade the current air filtration system in any type of housing, including modern studio apartments, nine-story buildings, gardens in the country, and homes built by Khrushchev.

Combined ventilation in the kitchen

When handling intricate technical tasks, it is advisable to consult experts who are well-versed in installing kitchen hoods in private homes and apartments. Simple tasks, like installing a conventional axial fan, can be done on their own, though.

Errors when installing a kitchen hood

The most frequent mistake is the duct’s deaf connection to natural ventilation.

Naturally, some allow some air to flow naturally through a grille, but they also manage to block it entirely.

Connecting a powerful hood with a large output flange to a duct with an inadequate diameter by means of an adapter.

D = 125mm is the recommended dimension for round ducts. 204*60 mm is the rectangular size.

The duct’s output is connected to the street via a homemade wall opening.

Generally, the rules forbid doing this. Furthermore, the text will make specific points.

Naturally, you could also lay a separate box directly to the facade’s roof. But is it worthwhile? Although such a solution is commonly used in cafes and restaurants found on the ground floors of high-rise buildings.

By the way, only high-rise buildings are subject to the restriction on air output to the street through the wall; private residences are exempt.

The route has a complicated geometry with lots of curves and transitions.

It will have an impact on the noise first. Naturally, the turns themselves are not the worst kind of evil. Occasionally, you cannot function without them.

It’s the exact turns that proceed one after the other without hitting any overclocking zones.

Connecting an overly powerful hood—say, 1000 m3/h—to a typical ventilation room, which can only lose roughly 300 m3/h.

Recall that a 200–300 m3/h performance is more than sufficient to remove all odors in an excellent manner while putting the least amount of strain on the home’s ventilation system.

Incorrectly installed hood height. The construction of a plastic ventilation room lacking adequate compaction or the placement of components on superglings.

I assure you that this design occasionally needs to be disassembled.

The upper—rather than the lower—position of the fissures in the ornamental grate within the air duct frame.

It is explained later on why this is a mistake and when you can make this.

The lack of a separate outlet beneath the hood in the upper portion of the wall.

Its connection is therefore similar to that, using carrying and extension cords. Remember that this is still an unsecured device, just like a fan, heater, or portable air conditioner.

Thus, the wiring for it must be done carefully and in a stationary manner.

Improper installation of a check valve.

Make sure that the cuts and installations follow the proper inclinations and angles. He will work every other time if not.

Hood installations can generally be broken down into two major phases. Its electrical connection is shown here first. The duct device and everything related to it come in second.

Connection of the hood to electricity

Kitchen hoods are considered household electrical appliances, so there shouldn’t be any issues with their connection, especially considering that their power usage is rarely more than 1000 watts. While grounding is ideal for all electric devices, it isn’t always possible to provide.

Use the valo terminal to attach the hood.

Grounding or stabbing can be done if major repairs are carried out in the apartment or house. In this case, the task of connecting the hood in the kitchen is greatly simplified. To do this, in the lighting shield, you should find a point in the form of a welded bolt, which is connected to the body of the electric distribution panel. As a rule, this point has a connection with the grounding of an electrical substation. As a grounding conductor, it is permissible to use a single -core or multi -core wire, with a cross section of at least 2.5 mm squares. It is better to use the wire in heat -resistant insulation.

As a rule, in our time, when buying electrical household appliances, some of them are not equipped with a wire with a fork, while there are models with the presence of a wire and a fork, but there are models that have a wire, but there is no fork. Such hoods can be connected without a fork, but this is not a very good option. If you have to remove the hood to clean, then this is not very convenient, since it will take a lot of time to turn off such an extract, and the connection too. Therefore, it is better to go to the store, buy a fork and connect it to the wires. In this case, to turn off or connect this device, just pull out or insert the fork into the outlet. If there is grounding, you need to buy a fork with grounding pins, and if there is no grounding, then the most ordinary fork is suitable, but it is better under the Euro -zeettes, since the former Soviet sockets are no longer in demand. The fact is that they are unreliable, and they are intended for domestic forks, in which contacts have a smaller thickness.

Organization of grounding

It is not necessary to dig a trench and hammer metal rods into the ground in order to arrange grounding. Grounding the hood to the heat center, gas pipeline, or water supply pipes is not permitted.

Finding a neutral and connecting to it are the first steps in setting up grounding in the home. To do this, open the common shield at the entrance. Its wires are contained within a pipe that is set into the wall. A threaded pin, which is a neutral and indicates that the pipe is consistently grounded, should be present.

A multi-core cable with a cross section of at least 2.6 mm² must then be taken, connected to neutrals, and drawn to the intended outlet. An apparatus for protection must be used to connect the hood to the power source at 6.4 a.

We’ll examine the fundamentals of kitchen ventilation in this post, including how it operates and how to put up a functional system. Kitchen ventilation is essential for preserving air quality and getting rid of grease, extra moisture, and cooking smells. We’ll go over forced and natural ventilation systems, including how they work and how to install them. Gaining an understanding of these principles is essential to creating a comfortable and healthy living space while cooking, whether it’s selecting the appropriate type of ventilation for your kitchen layout or making sure there is enough airflow to prevent the accumulation of pollutants.

Possible problems of arrangement

It is occasionally possible to violate the standard apartment ventilation system when installing equipment. The ventilation channel or the hole in the exhaust device, in particular, can be broken in an effort to solve this issue. However, this approach is not feasible because the ventilation channel’s cross sectional area does not grow when another hole is made in it.

If everything goes according to plan, just slightly over half of the kitchen’s odors will exit the room and stay there. All of the tainted air will return to the room or go to the neighbors if the wind picks up from the street or if there is a craving from nearby floors.

Regarding the use of a wall hole to remove air to the street, this violates the supporting structure. These projects must be approved by the appropriate authorities and offer the project’s initial development for the impending changes. A short circuit is nearly certain with such a solution since it can also increase the risk of condensate formation on the fan electric motor as well as in the air vent. Using a separate section of a ventilation box with a clap valve is a better solution in this case.

Typically, the damper is composed of fiberglass, fluoroplast, or aluminum sheet with a thickness of 0.6 mm. Aluminum is the ideal material to use for this kind of product because the damper’s stiffness, thickness, and weight are all crucial. When the manufacturing material has a low specific gravity, the cracker operates more effectively.

There is a thin spring attached to the damper. Its primary function is to allow the damper to smoothly return to its initial position if it is raised up and the impact on it ceases. A wire with a diameter of 0.25–0.4 mm is required to manufacture the spring. The spring itself has a diameter of 4-6 mm and measures 130–140 mm.

Maintaining a healthy and cozy living space requires adequate kitchen ventilation. The kitchen produces a range of airborne pollutants, moisture, and odors whether you’re boiling water or cooking up a storm. These air pollutants can remain in the air without sufficient ventilation, which can have negative effects on indoor air quality and even pose health risks.

It is essential to comprehend ventilation principles in order to design a system that works. Systems for forced or natural ventilation can be used to replace old air in the kitchen with new air. By forcing air outside, forced ventilation systems—like range hoods with fans—actively remove pollutants from the air. Conversely, passive airflow devices such as windows or vents are necessary for natural ventilation in order to promote air exchange.

The layout and location of appliances must be carefully considered when setting up the kitchen’s airflow. Cooking vapors and other airborne particles are more effectively captured and removed when range hoods are positioned directly above cooking surfaces. Furthermore, cross-ventilation can be encouraged by carefully placing windows or vents to let fresh air naturally enter the kitchen and exhaust stale air.

The size of the room, your cooking style, and your budget are all important considerations when installing the proper ventilation system in your kitchen. Forced ventilation systems are appropriate for larger kitchens or those with frequent cooking activities because they provide more control and efficiency in eliminating pollutants. On the other hand, natural ventilation systems can be more economical and energy-efficient, especially in climates with suitable outdoor conditions or smaller kitchens.

In the end, for best results, regardless of the type of ventilation system you choose—natural or forced—you must prioritize regular maintenance. You can extend the life of your ventilation system and enhance the quality of the air inside your home for you and your family by routinely cleaning range hoods, changing filters, and checking vents and ductwork.
