How to calculate the exhaust power for high-quality air purification? Choosing the size of the kitchen hood

You can't do without a hood in the kitchen. Smells are eternal companions of culinary experiments. Evaporation of liquid during cooking The best way extend the life of a new repair. In general, an extractor hood is a kitchen device whose value and necessity are obvious. In our online store there are hoods of all popular types. In this material, we will help you figure out what should be considered when buying a hood.

Hood types

In our online store you can buy traditional block hoods, as well as domed and built-in hoods. All of them differ from each other in design, installation method, performance and some other characteristics.

Traditional hoods

Operating modes

Most modern hoods have two modes of operation: exhaust and air circulation. However, there are models where one of the modes is not available, so check this when buying.

In the extraction mode, all odors and fumes are removed outside the room - into the ventilation shaft. The efficiency of the hood in this case is high, but there is a problem: connecting to ventilation system not always possible. If you can still connect the hood to the ventilation, then a special additional duct, which is usually attached to the kitchen wall, can significantly spoil the interior.

In circulation mode, no additional air duct is needed. The air passes through the filters inside the hood (see below) and is returned back to the room. This method, of course, is somewhat less effective than a complete replacement of air, removing it from the kitchen, but still it is often more convenient for users - no need to carry out any additional work, there is no danger of spoiling the design project of the kitchen. Sometimes it's just not possible to organize the air outlet. Circulation mode can also be demanded in winter when it doesn't come out to release properly warm air from the premises.

Filter system

The hood is, of course, not a full-fledged air cleaner. However, it quite well removes fats and odors from the air that has entered it.

A metal grease filter is used to remove grease. First of all, it is needed so that fat does not settle on the elements of the hood motor - this can lead to failure of this important detail. Such a filter, as a rule, is removable, it can be washed, it works during the entire life of the hood.

A carbon filter is used to remove odors when the hood is in circulation mode. It may be included with the model. Sometimes it needs to be purchased separately. In our store you can buy various accessories for hoods - including a carbon filter. Depending on the operating conditions, the carbon filter should be changed every 4-6 months.

Many hoods provide signaling when the carbon filter needs to be replaced or the metal grease filter needs to be serviced. This can be, for example, a light indication on the control panel. A simpler option is special symbols on the filter, which disappear as it gets dirty.

Performance and Power

Most important technical specifications any hood - its performance. We are talking about how many cubic meters of air it can pump (take it out into the ventilation shaft or clean it and return it to the room) per hour of work.

Before buying, it is advisable to calculate the performance of the hood, taking into account the characteristics of the room, the length and bends of the additional duct (if you plan to work in the extraction mode). You need to multiply the volume of your kitchen by 12, because according to Russian sanitary standards, the air in the room should change at least 12 times per hour. For more accurate calculations, you can subtract the volume from the volume of the kitchen. kitchen furniture. But you can not do this - get a small margin of power, which can come in handy.

For example, for a kitchen with an area of ​​​​12 m², with a ceiling height of 2.7 m, a hood with a capacity of 390-400 cubic meters of air per hour would be a good option. But there are additional factors to keep in mind. So, the hood should be at a height of 65–85 cm above the hob. If you will hang higher - it is better to take a model with a performance margin.

On the other hand, it should be understood that often throughput ventilation duct (shaft) in houses is limited, because the construction provides for the so-called natural ventilation premises. And this throughput can be noticeably lower than the capacity of your hood (for example, about 200 m³ per hour). In this case, you can buy a more efficient hood only in order to reduce the noise level from its operation, including not at maximum power.

Add here more cases when residents, for some reason known to them alone, generally block ventilation shafts - in this case, all smells will go to neighbors and can partially return back (if the hood does not have a special mechanism that does not allow reverse flow).

The solution could be the output of the "exhaust" air not into the ventilation shaft, but directly to the street, through a hole in the wall of the correct diameter, to which the air duct is connected. However, this is not always possible, especially in high-rise buildings.

If you are going to use the hood only in the air circulation mode, remember that its performance in this case is approximately two times lower than in the extraction mode.

When choosing a hood, it is worth considering culinary traditions. For a family where they cook often and a lot, you need a device with the highest possible performance for specific operating conditions. For those who rarely eat at home and cook little, high productivity is useless.

Also remember that in a small kitchen the concentration of odors during cooking is usually higher, so it is better to have a hood with a small margin of performance.

The performance of the hood directly depends on its power. So you should pay attention to this parameter when choosing a hood. The power of modern models rarely exceeds 500 watts - this is quite enough for a very high level performance.


Control system

Modern hoods can be mechanically or electronically controlled. In the first case, the speed of work, as well as the lighting, are turned on by pressing the corresponding buttons. A slide switch can also be used to adjust the speeds. This is a simple and user-friendly operation.

Electronic control usually provides for a display that shows the working settings of the hood, the active mode of operation. Activation of speeds and lighting can be done by touching the sensors (although it happens that the button format is saved).

In models with electronic control, a timer function is often available - you can set the time for turning off the hood or switching to another mode of operation.

It is the electronic control that allows the auto-on function of the hood. Thanks to temperature and humidity sensors, the device itself will “understand” that the cooking process has begun and will turn on. At the same time, the intensity of the hood operation may change - depending on the saturation of the air with odors, etc. At the end of cooking, the hood will work for some more time to remove all the polluted air, and automatically turn off.

There are also hoods equipped with smoke detectors. They also automatically turn on or increase productivity when smoke increases in the kitchen (something is burnt, smoky).

Remote control

A continuation of electronic control, in fact, is the ability to control the hood remotely: from a smartphone or tablet, from anywhere in the apartment, city or world. To do this, you need to have wireless Internet (Wi-Fi) working at home. By installing on your mobile gadget an application to control the hood (or in general various kitchen appliances), the user can turn the appliance on and off, set operating speeds, set a timer, etc. In this case, control of the power consumption of the hood is often also available. And the device also sends a message that it is time to change or wash the filter, and even that increased smoke has been registered at home.

An air purifier or extractor hood to the kitchen cannot be compared with ordinary ventilation; unwanted odors may not completely disappear with the old method. And not every weather allows you to ventilate the room. Therefore, it is right to choose a good one, quality hoodthe best option way out.

Conventionally, it is customary to divide air ducts into domed, flat and built-in. Each type has its own distinct advantages and disadvantages.

Types of hoods for the kitchen:

  • flat. They have a laconic shape of the body, outwardly resemble a plate attached to the wall. The air is purified by a filter system.
  • Dome. The dome shape is characteristic of this species. This hood always removes evaporation outside the kitchen.
  • Embedded. Placed on a countertop or kitchen cabinet. The air does not have time to rise up, so the spread of odors in the kitchen is excluded.

Each type of hood deserves more detailed consideration.

Flat hood - how to choose the best option

Otherwise, this hood is called traditional, standard, suspended or mounted. In either case, the same type of construction is implied.

It is called hinged in sign of its method of attachment to the wall. Such an extract does not need to be connected to the ventilation system of the house. The right place is simply determined on the wall, dowels and fixing anchors are taken, and the hood itself is quickly attached.

The air cleaning method depends on the model of the hood. There are devices with single-stage cleaning, the simplest acrylic filters are used. More modern models are available with a two-stage air purification system.

Stages of cleaning the air of a flat hood:

  • The hood captures air, and first of all it is cleaned of fumes, fat, coarse soot impurities. Grease filters are responsible for this process (or coarse filters). It is better to use reusable filters in the hood.
  • After the first stage of purification, the air enters the area of ​​action of the already fine filters. At this stage, the air is purified from unpleasant odors and those particles that did not come out in the first place. Usually they do it carbon filters, the adsorbing properties of which are quite effective.
  • The final moment is the return of air to the kitchen already purified.

Flat hoods can be chosen at least thanks to the following list of advantages:

  • external attractiveness;
  • democratic price;
  • does not interfere with natural ventilation;
  • compactness.

It is impossible not to note the disadvantages of this type of hood:

  • rather low motor power;
  • high noise of the device;
  • the need for constant filter replacement.

Someone believes that a flat hood is an outdated version, but this opinion is erroneous. They still sell well, because for many families the price issue is decisive.

How to choose the right dome hood

The kitchen dome hood must be selected according to the conditions where it will work. The most optimal option is considered to be with a chimney hood.

The fireplace hood is similar to the ventilation system for fireplaces. There are some simple requirements that apply to a good fireplace hood:

  • The presence of an air duct. Provides regular air flow.
  • Stainless steel - material of manufacture. Perhaps the most best option for kitchen. Choice determines high stability to the effects of chemicals.
  • Powder painting method. It is considered more stable than enamel.
  • One motor block for conventional kitchen. If enhanced ventilation is required, it is better to choose a hood with two motors.
  • Liquid crystal display. A little better than a push-button, the advantage is perhaps in the modernity of the model.
  • Two kinds of filters. Both fat-absorbing and coal in one device - this is the best option for the kitchen.
  • Style Match. In a country-style kitchen, a model for a classic interior will not be appropriate.

A dome hood is the best hood option for a spacious kitchen. But in a small kitchen, installing it is not very correct.

Built-in hood - how to choose

You can also choose an air cleaning system so that it will not be visually noticeable in the kitchen. Such hoods are convenient, take up little space, have an attractive price and variability of configurations.

Models vary in the most important characteristics, among which:

  • Size. Depends on the dimensions of the plate. And it can be 50 cm, and all 90 cm.
  • Number of power adjustment steps. The faster the better.
  • Number of built-in filters. From one to four.
  • Embedding option. It may be horizontal or it may be vertical.
  • Additional features. Timer or backlight, remote control, etc.

The built-in hood works as follows: it draws air above the stove into itself, it passes through a replaceable filter. The recirculation process begins and the purified air is returned to the kitchen area.

The door in the kitchen or the window in another room can be left open, but it is not recommended to open the window in the kitchen. Otherwise, the hood will suck in air from the street, and recycle it instead of air above the stove.

Another point - the more powerful the hood, the more noise it makes.

What material should the hood be made of?

AND appearance, and of course, the price of the device depends on the material used. Enamel is a durable, cheap, easy-care material, it is right to purchase such a hood for small kitchens.

Polished stainless steel is an expensive choice, but the appearance of the device is incomparable.

Tempered tinted glass - you can choose such an outwardly attractive hood, but stains can affect its aesthetic properties.

Of course, it is worth focusing on the price of the device.

How to choose a hood by power

Typically hoods have one or two fans. Food for them is directly electricity. The performance of the hood depends on the operation of the fans. Modern hoods are distinguished by a large run-up in this parameter: from 180 to 700 m3 / h.

Fans operate at two or four speeds. Do not think that high performance is good from all sides: if you are annoyed by noise during operation of the hood, then it is better not to choose such powerful devices.

According to sanitary standards, it is believed that the air in the kitchen should change 10-12 times within an hour. The calculation is easy to make: the volume of the kitchen is taken as a basis, the volume of furniture is subtracted from it, and this number is multiplied by 10. The result obtained is the performance coefficient of the device.

Hood control panel

The control panel can be of three types:

  • Buttons. The most simple and familiar control.
  • Sensor. A light touch on the desired sector, the LED lights up, and a command is given to the device.
  • Slider. A mechanical slider is used that moves across the panel.

Touch control is more convenient, but the cost of the hood will be higher.

Conclusion

Choosing a hood is not so difficult, knowing the "pros" and "cons" of all types of construction, and taking into account which appliance is right for your kitchen. In any case, the choice is huge, both in terms of price and in terms of requirements for modern market you can find the perfect match.

It takes ~4 minutes to read

It is difficult to imagine a modern kitchen without a hood. Stuffiness, the smell of cooked food, an unfavorable climate in the house, a dirty coating on furniture, walls and ceilings - all this has long been a thing of the past due to the invention of such an indispensable assistant. Before answering the question of how to choose a kitchen hood, you need to understand what they are, consider their functional features, types, and only then choose. Tips from the pros in this article.

Why are kitchen hoods above a gas stove required?

Quite a lot depends on the state of the air: from the well-being of family members to the taste of dishes that are stored or prepared indoors. Unpleasant odors impair appetite and spoil the mood, and due to poor air ventilation, dizziness can occur, which is why it is necessary to purify the air.

Ventilation in the kitchen does not greatly save from the smell of burning in working area, therefore, in order to improve the microclimate in the house, odors must be eliminated directly above the stove. To complete this task, you need to know which hood to choose for the kitchen.

If you choose a hood for the kitchen, then you want it to be quiet, efficient, look stylish in the interior, be not very expensive, reliably improve the home microclimate, and require simple installation. How do you determine which one is exactly what you need? It depends on many parameters, which we will describe in this article.

Do you need an extractor hood in a kitchen with an electric stove?

Most people, when buying an electric stove, often ask if it is necessary to choose a hood for it? There is a misconception about its unimportance when installing induction or electric tiles. Electric stoves do not emit carbon monoxide- this is their main advantage. But when cooking on it, the smells are exactly the same as the presence of burning when frying dishes. The smell of food throughout the house is not a very pleasant moment. Therefore, we can say with confidence that the choice of hoods for the kitchen with electric stove must be approached in exactly the same way as if you had a gas stove.

Varieties of hoods and their right choice

It is possible to classify such varieties according to the form: dome, built-in and flat suspended.

Suspended

The most popular type is hanging. These devices are cheaper than all other models, their installation is not very difficult and does not require the participation of professionals. This equipment is placed above the hob, and a cabinet can also be installed on top of it, since the flat model does not require installation clearly under the ventilation duct.

Air purifiers of this type in the interior may look bulky, but right choice, on the contrary, will emphasize the notes modern design or classic elements. The flat model is equipped with replaceable filters, which are best replaced in a timely manner for efficient operation.

Embedded

Embedded equipment is mounted in a special cabinet and is almost imperceptible. Outside, you can only see directly the exhaust surface. They are equipped with an air duct that enters the ventilation duct: it is located behind the cabinet doors.

Most built-in products are equipped with a retractable panel, which makes it possible to increase the working surface of the device. These models have a low noise level, attractive design, which is invisible in modern interior as well as retro.

Dome

These hoods are the most interesting and fashionable option. There are design models that kitchen interior take the lead. The devices resemble a fireplace chimney: a dome and a thick channel. They will perfectly fit into the style of retro or classic. In terms of design, these air cleaners are the most diverse. Colored, black or white, glass, wood or metal, hi-tech or retro hood - modern design solutions make it possible to choose the perfect device that will meet the most demanding taste. Retro design exhaust systems are quite popular in private homes.

In some cases, they are classified as domed, and in some cases, types such as those with glass and an island air cleaner are distinguished separately.

  • Island. Installed in the center of the room, fixed above the plate to the ceiling. This original installation is used in the interior, in which the working part is made in the form of an island. The round shape looks the most interesting - its surface can be either curved or flat. These types of products are suitable for kitchens in retro design in the spirit of TV cooking shows.
  • With glass. This model is designed to solve not only its main task, but is also a design element. In these devices, the backlight looks the most interesting, especially when the hood with glass is not just transparent, but black, white or, for example, smoky. Glass varieties are not suitable for retro design, as they look super modern.

Air purge mode

Air purifiers can be of three types:

  • recirculation;
  • flowing;
  • combined.

Flow hoods are called hoods with an air duct (connection to ventilation). The air begins to be captured by the fan impeller and is immediately removed from the room through the channel. According to this principle, the classic old models in the retro style familiar to many work. Flow-through varieties of devices emit less noise, unlike recirculation ones.

Kitchen hoods with an air duct, although more efficient than recirculating ones, have one significant drawback: a complex installation. At the same time, it is not always possible to make a technological hole for their installation, the ventilation channel may be too far away or absent.

Many modern models can operate in a combined mode (circulation - outlet), can be used autonomously, or can be brought under ventilation. At the same time, they are equipped with the ARS system, which reacts to the smell of burning. Due to this system, the air cleaner automatically turns on at the signal of the sensor, this makes it possible to capture even slight odors.

Parameters and performance

This is another important parameter that shows how much air the device can “pump” per unit of time. The larger the kitchen, the higher the performance must be.

To find out what performance you need to choose specifically for your kitchen, you need to calculate the volume of the room by multiplying its height by the area, and multiply the resulting figure by 12. But even for small kitchen it is desirable to select products with a capacity of at least 300 cubic meters / hour. The most popular performance for modern exhaust systems: 1000, 850 and 700 cubic meters / hour.

Control Panel

Hoods differ in the way they are controlled. The following types can be noted:

  • touch (non-convex flat buttons);
  • push-button (convex buttons);
  • remote (using the remote control);
  • slider (horizontal mechanical switch).

It is difficult to determine which varieties are better in terms of control - the choice will be determined only by your preferences and the general interior of the equipment in design: in modern style a button or slider panel will fit best, and a touch panel in retro. But it should be noted that buttons and sliders are more difficult to clean and get more dirty, which cannot be said about their more modern counterparts.

Connection to communications

Proper installation of the cleaner is a guarantee of its quality work. To connect the device to the ventilation system, short pipes must be used. The more knees the ventilation channel has, the worse the performance of the device (one bend reduces this figure by 4-6%).

It is advisable to select a duct with a large diameter and smooth walls. Corrugated hoses, regardless of their convenient installation, significantly reduce performance.

How to choose by size

The choice of size will depend on the dimensions of the plate: the size must be no less (and preferably more), narrow devices will not fully be able to do their job. The standard sizes that are usually on sale are 900, 600 and 450 mm.

The air cleaner is installed in height taking into account the type hob. All cooking surfaces, without exception, require air purification - from the Soviet old retro stove to the induction or modern electric panel. The level above the gas stove, on which the air purifier is placed, is at least 85 cm, and above the electric one, it can be set within 65 cm.

Noise level

This is also one of the important indicators when choosing any device for home use. No matter how effectively he copes with his task, excess noise causes discomfort to the owners, causes irritation and can even provoke a migraine.

The ideal model should be quite powerful, but at the same time quiet, not create excessive noise, so as not to cause inconvenience to its owners. Professionals advise purchasing a hood with a noise level of no more than 60 dB. The lower the manufacturer claims the noise threshold, the better.

Production material

The choice of high-quality material for the case is quite important. Budget exhaust systems are made of enamel. Polished stainless steel looks more solid, but this is also reflected in the cost of devices. At the same time, steel is more finicky in care, soot adheres to it more strongly, and it is impossible to clean it with abrasive compounds - scratches will appear.

Glass hood made from tempered glass, which is resistant to temperatures and damage, closes the ventilation channel, protecting it from contamination. But the glass surface needs to be cleaned almost daily, otherwise stains and streaks will spoil the whole look. In order to properly care for this surface, it is necessary household products for glass cleaning.

Lighting

Lighting above the stove will never be superfluous, because modern kitchen hoods are equipped with lighting. It can be an incandescent, fluorescent or halogen lamp. As a rule, light sources are installed in the far part of the device.

IN modern models you can find a rotary lamp, with it you can focus the flow of light in the required part and change its intensity. The exhaust system with glass, as a rule, is equipped with a significant number of fixtures and can even replace a chandelier in the kitchen.

Additional functions

In addition to the main function, modern models have additional ones. It will be right to choose good device which is equipped with them. As a rule, there can be two additional functions: residual stroke and interval switching.

  • Residual stroke - after turning off the device, the fan will operate in quiet mode for 10-20 minutes to best cleaning air and getting rid of odors that remain on the stove after cooking.
  • Intermittent switching - the hood turns on periodically after a certain period of time. This function is required in order to continuously supply fresh air.

The range hood is an essential appliance in the kitchen. It makes it possible not only to enjoy fresh and clean air but also protects interior decoration and furniture from premature wear. Choose the right hood, even budget model can create in the kitchen comfortable conditions.

Today, a kitchen hood can be called an integral part of every kitchen, because thanks to this type of equipment, you can quickly rid the room of a variety of extraneous and unpleasant odors, as well as fumes that are harmful to human health that occur during cooking.

However, its effectiveness depends on the model chosen and the conditions in the house.

What are extracts?

Today hoods are produced standard sizes(120, 90, 60, 50 cm), therefore, taking into account this criterion, it is necessary to choose a model based on the size of the stove (should be slightly smaller than that of this technique).

It should be noted that there are extracts custom sizes however, they are quite rare. This type household appliances can be freestanding or built-in, made of glass, plastic, as well as aluminum and stainless steel.

Principle of operation

According to the principle of their work, hoods are divided into two types. The first of them includes models through which the outflow of air is carried out outside the kitchen. These systems are connected directly to the chimney or directly to the ventilation duct.

The second group of hoods works on the principle of recirculation, which means that all extraneous odors are passed through special filters and then returned cleaned to the room.

These functions include the main part of modern models. However, in order for this kind of hood to work as efficiently as possible, they must be additionally equipped with carbon filters.

It is extremely important to know that the combination of a geyser and an exhaust hood is unacceptable.

Power

When choosing a hood, you must Special attention pay attention to its power. There are models on the market, this indicator of which ranges from one hundred and seventy to one and a half thousand cubic meters per hour.

Hoods with a certain power must correspond to the area of ​​\u200b\u200bthe room. Ideally, this technique should do six oxygen exchanges per hour, so in order to calculate the optimal power, you need to multiply the cubic capacity of the kitchen by six.

To simplify the choice of the most acceptable option as much as possible, sellers and manufacturers almost always indicate in the accompanying documents for the hood the indicator of the footage of the room for which the selected model is intended.

The most affordable hoods are designed for kitchens, the square of which does not exceed sixteen square meters. The most powerful devices cope with the task in a room whose area does not exceed twenty-eight square meters.

The minimum productivity of professional hoods is eight hundred cubic meters per hour.

Noise level

An important factor that you need to pay attention to when choosing a hood model is its noise level. It is logical that the noisy operation of the device will cause only negative emotions.

The most optimal are those models that, during their operation, create noise not exceeding forty-eight decibels. The minimum indicator in this case ranges from 30-70 decibels.

Appearance

When purchasing a hood, it should be noted that it must necessarily fit into the design and interior of the kitchen.

There are models that are able to maximize the expressiveness of the design of the room, while becoming its dominant object. Other hoods can fit quite discreetly into the kitchen space.

When choosing this technique, it is important not only to consider it design solution, but also the principle of its installation. For example:

  • Dome type hoods are attached directly to the wall. This type can be subdivided into corner models and beveled models.
  • "Island" hoods can be distinguished in separate group. They are intended to be installed above the so-called "kitchen island". Models of this type are of an extremely respectable type, often equipped with original backlights.
  • Built-in hoods also deserve attention. They can be fully built-in (can even be built into the bottom of the wall cabinet, which is located above cooker), and partially built-in or telescopic. There are also models that are built into the wall and placed directly above the kitchen worktops.

Filters

Filter hoods also should not be bypassed. They are of two types: coal and fat.

Fat filters easily retain the smallest particles of fat, however, when using them, it is recommended to use reusable metal filters, which are quite easy to clean and dismantle.

The main purpose of carbon filters is to eliminate unpleasant odors. They need to be replaced according to all the rules that the manufacturer specifies. The service life of such filters can be limited to several months or years.

Lighting

Since the hood is located above the hob, it is also an extremely convenient place to place the backlight. Manufacturers willingly use this opportunity and equip hoods with various lamps. These can be fluorescent lamps, conventional incandescent lamps or halogen lamps.

Their number and location can be varied. The most common option is the far part of the model, the least convenient - near the wall (in this case, only back row burners). In modern models, it is possible to change the intensity of the light flux, focusing the lighting only over the work surface or over the entire kitchen.

Control Panel

All modern hoods have a simple intuitive control. Typically, the panel consists of a button that turns on the backlight, as well as buttons for selecting the operating mode with different performance. This control option is the most reliable, simple and cheap.

Sometimes buttons change to sensors. In this case, a light touch is required to activate the functions. Often touch control accompanied by an LED indicator. Sometimes a mechanical switch - a slider - can be used to switch power.

However, there are also complex systems control, including with a special LCD display, which reflects information about performance, operating modes, backlight level.

Modern technologies

To date, there are models of hoods that are equipped with unusual features that make it possible to simplify the operation process as much as possible.

These can be attributed remote control, programmable electronic systems, automatic switch-on sensors (activated when the humidity rises in the kitchen), the ability to work from the hob (without human intervention).

How to choose the right hood for a gas stove: highlights

Thus, in order to choose the right hood for gas stove it is necessary to take into account its size, required power, noise level, type of desired lighting, control method, filter type.

Only after a thorough study of all the features, advantages and disadvantages, you can maximally protect the kitchen from extraneous odors and create comfortable conditions for cooking.
