Choosing a hood for the kitchen is enoughresponsible business. This issue should be approached with special attention. Before you visit the store and make a purchase, it is worth to determine in advance the type of hood. This will avoid many problems. After all, not everywhere you can install a classic hood. In some cases it is simply impossible to equip an air duct. Of course, this is a problem. But there is always a way out. In such kitchens, as a rule, an extractor without a duct is installed.
At the moment there are several types of kitchen hoods. Each of them has its own shortcomings and advantages. But the main difference lies precisely in the principle of action.
Flowing hoods
They work on the principle of air exchange.Such a hood draws air from the kitchen and steam, and then through the ventilation ducts throw it all into the general ventilation duct of the whole building or to the street. This allows more effective removal of unpleasant odors. At the same time fresh air comes from the street through loosely closed windows. It is worth noting that such systems are considered the most effective. This is achieved due to the fact that the hood, tightening the polluted air, frees up enough space for a clean one. However, the main disadvantage of such a ventilation system is the need for air vent equipment. It is necessary to remove polluted air.
Recirculation systems
Their working principle is significantly different fromprevious. Hoods without air duct for the kitchen, the photos of which are presented in the article, draw pairs and polluted air into their tank. This is done with a sufficiently powerful motor. Once in the system, the air is cleaned. In this case, the flows pass through special filters. The cleaned air is returned to the room. It is worth noting that the hood without a duct is usually equipped with a two-way filtration system. This makes cleaning the streams more efficient. So, the first filter is able to purify the air of enough coarse particles of coke, soot and grease, and the second performs deeper cleaning, removing those particles that create unpleasant odors.
At the moment, many manufacturers produceExtraction without duct only in several modifications. If desired, you can purchase a flat or built-in system. Each of the models has its own peculiarities.
Flat exhaust is a device,consisting of a fan, filters and a cabinet panel. Such units are horizontal and vertical. It is worth noting that such hoods in the kitchen without a duct have a fairly compact size. Such models fit perfectly into almost any interior. More modern and aesthetic look chrome hoods, as well as those that are made of glass or aluminum.
Built in the kitchen without a ductare devices that are closed with a special panel or a hinged cabinet. Such models can easily be hidden from prying eyes. A very popular telescopic system, which also refers to embedded. If necessary, such an extract can be pushed out and then removed, putting it into a non-operating mode.
Very often recycling systems causecondescension. Someone is completely satisfied with the hood without an air duct, while others do not satisfy them. However, many do not even know what positive qualities such systems have.
When the hood with duct works, then, inprinciple, everything is in order. Always clean air in the room. But what happens if the system is turned off? If the flow-through hood does not work, there is a violation of natural air exchange in the room. As a result, the quality of ventilation deteriorates by about half. This is due to the fact that the main channel is blocked by a pipe.
The hood without a duct works perfectly foranother principle. When the system is switched on, air recirculation begins. When the hood is switched off, there is no disturbance to the natural air exchange. After all, the main channel is blocked. This is the main advantage of the system. In other words, the hood without the air duct does not interfere with the natural air exchange in the room.
Another advantage characteristic of the hoodWithout a duct, this is the ease of construction. Such systems are not equipped with massive pipes. In addition, for the installation of the hood, no additional stretching of ventilation connections through the entire room is required. A system without a duct is a flat and fairly compact surface that can be positioned horizontally with respect to the floor. In addition, the construction does not create loads on the walls, nor does it spoil the overall interior of the kitchen.
Extract without duct is very easyis established. The system can be installed on any flat surface with the help of ordinary construction tools that can be found in every house. It only remains to connect the hood to the mains. This does not require additional adapters. After installation, the system is ready for use.
Another advantage that the extractor haswithout a duct, is the ease of maintenance. Filters of such a system are very easily changed and cleaned. Hoods in the kitchen without a duct are equipped with several levels of cleaning. In this case, each of the filters has its own characteristics. They are made of different materials. For example, the coarse filter is made of metal. In the latest models began to install several medium products. In this case, a large filter is simply replaced. It is very simple to look after the products - the filters can be removed and thoroughly washed. For this purpose, non-abrasive detergents can be used. You can wash the filters not only manually, but also in the dishwasher. It's much more convenient. As for coal filters, they need to be changed.
Extraction to the kitchen without a duct has andsome drawbacks. First of all - regular replacement of carbon filters. This requires additional costs. Of course, many are interested in how much coal filters cost and how often they need to be changed? It is quite difficult to answer these questions unequivocally. These indicators directly depend on the frequency, as well as the intensity of the use of the hood. It should be noted that the status of the filter is also affected by the presence of people smoking in the apartment.
As the reviews show, an average of one productenough for 3-6 months. Do not forget that many models of modern flow hoods are also equipped with filters that need to be replaced after a certain period of time.
In addition, many consumers believe thatall fit the hood in the kitchen without an air duct. This is far from the case. Such systems provide air cleaning at the proper level. But this is not the main advantage of hoods without an air duct. After all, recirculating devices are not able to disturb the balance of the ventilation system of the building, in contrast to flowing.
The demand for hoods without a duct is not so muchis great. This factor is influenced by many factors, including the appearance of devices. Produced hoods in the kitchen without a duct in a smaller design variety. Of course, in general, the systems differ in a concise manner and in the simplicity of their forms. However, in contrast to flow-through hoods, recirculation looks much more modest.
Before you buy a hood without a duct,it is worth paying attention to several factors. This will avoid significant problems in the future. First of all, you need to determine the performance of the device. To do this, the height of the kitchen walls must be multiplied by the area of the room, and then multiplied by 12. The number that will be obtained in the response will be the necessary performance indicator. Select electric hoods for a kitchen without a duct required in a certain segment.
Also, special attention should be paid to the dimensionsdevice. Many choose on the principle: the more hoods are larger, the much better. However, it is not. It should be remembered that too large devices are equipped with motors of the appropriate size. As a result, such systems, when turned on, create a lot of noise. Do not install a large hood in a small room.
When choosing a system, special attention should be paid toto give the noise level. This indicator many manufacturers indicate in the technical characteristics of the product. As consumers' reviews show, it is best to choose hoods without air duct with a noise level of 40 dB. These devices produce relatively quiet sounds.
What should be the cooker hood for the kitchen withoutductwork? Customer feedback indicates that it is worth choosing devices with a fairly wide range of adjustments. The more of them, the better. This will allow you to optimally adjust the operation of the system.
