How to calculate the suction power and performance to the kitchen?

One of the useful parts of kitchen range hood is. Choosing a suitable model, it is necessary to consider not only the harmonious combination of its design to the interior of the room, but the popularity and reliability of the manufacturer. In addition, an important factor is the type of extraction, size and power. Before buying you need to make an accurate calculation of drawing power. After all, the performance is one of the most important parameters. The more powerful extractor, the faster it can purify the air in the kitchen.

Variety of kitchen hoods

The design presupposes a kitchen hood housing with a fan motor and filter. Many companies offer a variety of models of differing size, shape, design and materials. But mostly you should pay attention not only to the appearance of the product, but also its efficiency and productivity. On this depends on how quickly and effectively hood will deliver the room from unpleasant odors generated during cooking and fat burning, etc. To select the desired option for themselves to be calculated by simple mathematical power actions.

From drawing the design depends directly on the harmonious appearance of the entire interior of the kitchen. Therefore, to the question of the appearance of the product should be treated no less responsible than to functional features.

angular

It allows you to place it in a corner of the kitchen, and the appearance can be accomplished in a variety of styles: high-tech, classic, retro and others.

The island

This type of drawing is more suitable for spacious rooms, for example, in a country house. It has a kitchen in the center and is connected to the ceiling directly over the island with a stove or cooktop. The price of these products is much higher than the standard.

Decorative

With a wide range of models and brands other than price, design, functionality and performance, you can choose for themselves the appropriate option easily. This type of hood is most common among buyers.

Mounting

This type of model is very useful, since the product body is completely hidden in the wall-mounted kitchen cupboard, but it should accurately calculate its dimensions. This is perfect for the kitchen in the style of hi-tech, modern, and other modern interiors. Some hoods have in their structure the possibility of nominating the bottom panel, thereby increasing the working area. Prices for these products depends not only on the brand, but also from the functional.

flat

The most democratic of the value of an option. It is used in a confined space where everyone is important centimeter of usable area. Naturally, the power consumption is greatly inferior to other models.

functional types

Among the wide range presented in specialized stores, there are two basic types of hoods: flow and circulation.

flow hood

This type extracts works on the principle of removing the hot contaminated air into the ventilation through the air by an electric motor of the blades. The air penetrates through the metal filter, the walls of which are particles of grease, soot, soot and other impurities.

Such a filter requires periodic cleaning, otherwise extractor eventually cease to cope with their work effectively.

Also metal, this hood is no longer filters, e.g., absorbing odors, as it passed through the air is returned back into the room. The quality of this type of model depends not only on its power, but also on the air ducts in the building. Since slaughtered ventilation hoods partially lost productivity.

circulation type

This type of hood does not need to sum to the building ventilation. They may well do without it. With motor-contaminated air streams fall within the hood, passing through the special filter for initial purification. All the dirt eventually settles on the grid. Then the air is necessary to pass through a carbon filter, which removes all odors arising in the process of cooking. Then, passed through a double filter and totally purified air flows back into the room. This type extracts commonly used in private homes or old apartment buildings where ventilation is not cleaned for a long time and had not been repaired. Typically, these hoods more powerful than instantaneous.

Dimensions extracts

Before you choose a hood for the kitchen, you need to decide on its size. They tend to be much more effective to cope with the task model with dimensions equal to the area of ​​the cooking surface or exceeding it. Such articles are completely purify polluted air coming from the plate, or withdraw it into the ventilation.

Standard sizes of hoods usually have a width of 500 mm or 600 that corresponds to the dimensions of hobs and cookers. Some models may have a width of 800 to 1200 mm. But they are already in a more powerful version of semi-professional and even considered as suitable for hobs large.

By placing hoods also impose certain requirements. For comfortable use of the product should be on the hob at a height of 650-700 mm. If you hang it lower, it will interfere with the work at the stove, and if higher - the hood may not be able to fully cope with the task and clean the air properly.

Power extraction and its calculation

A fundamental factor affecting the extraction efficiency, is its power. The higher it is, the faster the air is cleaned in the kitchen area. Power hoods for kitchens determined cubic meters of air per hour. Thus, the minimum value must not be lower than 200-300 cubic meters per hour.

To calculate the suction power, you must perform the following steps:

• The first step is to measure the room dimensions (length, width and height). The values ​​obtained must be converted into meters and multiplied by each other, so it will be known the volume of the room in cubic meters.
• Next, you need to multiply the amount of space on the ventilation rate, that is a value indicating how many times renewed air in the room for an hour. Focusing on standards, this value must be equal to 10-12. Thus, it is possible to calculate and compute power.
• It is necessary to determine the mode of operation, that is, the type of extraction: flow or circulation. The first is considered to be more effective, but only if the duct is brought out, that is, on the street. But even in this case it is better to buy a powerful device to 600-1200 cubic meters per hour. For productive work drawing better if the window in the kitchen will be open, providing fresh air. This is especially true apartments with plastic double-glazed windows.
• Circulating embodiments are used in buildings with a clogged or blocked air duct, and passing the air assume two filter and returning it back to the kitchen. There will require capacity-drawing more than the flow of 30 or 40 percent. Filters in such models should be changed at least once a year.

If the hood is to be used in a private home, its capacity should be not less than 600 cubic meters per hour. The same applies to modern planning: for studio apartments suction power is better to increase by 30 percent.

Then it will be higher performance, and do not have to feel unpleasant odors from the kitchen, sitting in the living room.

noise and other important points

The higher the extraction efficiency, the more noise coming from it. This factor can be considered a significant drawback. the volume of the fan is operating normally specified in the instructions to the model.

If it does not exceed 45 dB, this hood is quite suitable for the kitchen. If the sound level of more than 55 dB, the product can only be installed in a spacious room, otherwise the noise might bring a lot of discomfort. Standard hoods typically have a three-speed operation, but there are models with five-speed. The minimum speed allows you to maintain the air in the kitchen clean and fresh, and the maximum mode to quickly save the room from unpleasant smells.

Manage the hood, you can use the buttons or touch panel. Some models are equipped with additional features such as a timer or an indicator showing the degree of contamination of the filter, as well as the ability to automatically turn on and off.

Cooker hood - an important detail kitchen facilities. If properly approach the issue of choice of power cooker hood, to decide on its appearance, performance and other features, you can be sure that the product is high quality and It lasts a long time. This technique will provide the premises clean and fresh air, and while cooking quickly eliminate unpleasant odors, not allowing them to spread throughout the apartment.
