Criteria for choosing compact supply ventilation to an apartment, office or country house

The choice of supply ventilation is not an easy task. Errors in calculations or in installation technology are too expensive, so the easiest way to ensure the required microclimate parameters in the room is to contact specialists. The general information about supply ventilation systems presented in the article is for informational and advisory purposes.

Parameters for selecting an air handling unit 

The purpose of installing a ventilation system is to create a favorable microclimate in the room (temperature, humidity, reduce the concentration of harmful substances emitted by the decoration of the room, minimize the concentration of carbon dioxide, inflow of fresh air). Calculations show that in order for the concentration of carbon dioxide not to exceed the maximum allowable values, it is necessary to provide air inflow in the amount of 30 m 3 / hour per person. For example, to calculate ventilation in an apartment : if 4 people are constantly in the room, then the installation capacity should be sufficient to supply 120 m 3in hour. In cases where the number of people in the room is constantly changing, it is recommended to determine the average value and start from it in the calculations. When selecting, it is also necessary to decide on the scheme of the ventilation system: whether it will be several separate compact devices, or one powerful installation.

Supply or supply and exhaust ventilation

For ventilation of urban apartments, experts recommend installing a supply ventilation system. Modern devices are equipped with a powerful filtration system, passing through which outdoor air is cleaned of suspended particles (dust, plant pollen, etc.), and sorption filters are able to remove harmful chemicals from the air.

When air is supplied to the room, excess pressure is not formed: the excess amount is effectively removed through regular ventilation shafts located in the bathrooms and in the kitchen.

For private houses, recuperators are more suitable, which provide efficient air and energy exchange. Electricity consumption for the operation of installations of this type is reduced by 20-25% due to the fact that the injected air is heated by the exhaust air. The devices operate offline, providing both air supply and air removal. In most household models, only a basic filter is installed that traps mechanical impurities, and the performance is designed for 1-2 people.

Exhaust system performance

Installing an air handling unit is meaningless if the exhaust system is not working or creates too little draft: in this case, the supplied air will simply not be removed. For this reason, before buying and installing an air inlet, it is necessary to check the effectiveness of standard ventilation, and, if necessary, carry out repairs or consider alternative options (for example, purchasing a supply and exhaust device or installing an alternative hood).

Issue price

Prices for exhaust systems vary widely, so you can choose the right option for any available budget. So, installing a supply valve on a window will cost at least 3.5 - 4 thousand rubles (with fan reinforcement - up to 10 thousand rubles). The cost of a device with a high degree of filtration, heating and adjustable performance starts from 24 thousand rubles. Additional options significantly increase the price of the device (remote control, carbon dioxide concentration sensor, etc.). The cost of installation work on the installation of a supply ventilation system usually does not exceed 5 thousand rubles.

Degree of filtration

When choosing supply ventilation, the level of air purification from pollution plays a decisive role. If the apartment or house is located in an environmentally friendly area, a basic filter is enough to remove mechanical impurities. To protect against allergies, it is necessary to choose devices that provide a medical filtration class H11. The carbon filter effectively protects against unpleasant odors and sorbs harmful chemical compounds.

The need for heating

Heating the supply air to the desired temperature is a very convenient function. But at the same time, it is very costly, because. The operation of heating elements requires a high power consumption. The cost of devices without heating is significantly lower, and efficient heat transfer can be ensured with proper installation of the system (for example, next to a central heating battery or buying a device that blows upwards, under the ceiling). Devices can be equipped with both adjustable and unregulated heating. In the first case, the heating function can be activated regardless of the outside temperature, in the second case, it turns on automatically only when the outside temperature drops below the set value.

Control

The simplest control option is a panel with conventional and touch buttons, by pressing which the operation of the device is regulated. A more "advanced" option is remote control using a remote control. With the development of modern gadgets, “smart” devices are becoming more and more popular, the operation of which can be controlled through an application on a smartphone. Using built-in sensors, the level of carbon dioxide is determined, and the performance of the device changes automatically. The operation of the device is optimized to ensure favorable microclimate parameters and minimize energy costs.

Noise level

Most supply ventilation systems are not accompanied by noise at low speeds: for people with normal sound perception, their operation is almost silent. Even with complete silence, the sound from the operating unit is practically not noticeable and does not interfere with sleep. If there are people in the family who are especially sensitive to extraneous sounds, then you should look at devices with a reduced noise level - up to 35 dB when operating in normal mode.

Summary

Based on the foregoing, it is not at all difficult to choose the right device to ensure effective ventilation in an apartment, office or country house, you just need to decide on the main criteria:

• required performance;
• type of device (supply, supply-exhaust);
• price category;
• degree of air purification;
• the presence of a heating function;
• noise level;
• control method.
