Which supply air purifier for an apartment to choose

Coming home, many immediately rush to the windows, open the transom, ventilate the room. This is a sign that ventilation is not working well in the room. It is a specialized small box with blades that let the waste, polluted air flow outside and let freshness into the room.

Brief description of the system

Despite the advantages of using a natural ventilation system in the house, ease and simplicity of operation, it is characterized by some disadvantages. So, the efficiency of its work does not depend on the required ventilation of the room, the performance is activated by random factors, such as the direction of the wind, etc.

In colder times, ventilation works more actively, although in summer, productivity is reduced to zero. It should be understood that the natural movement of air flows in the room is possible only with old wooden windows, although if modern Euro packages are installed, the natural ventilation system practically does not function.

Due to the high-quality sealing of plastic windows, mainly in the room of the bathroom, toilet, special air exhaust fans are installed in the kitchen.

In many situations, supply ventilation will be the salvation.

Supply ventilation system

The supply ventilation system can be performed in two main types:

• the main valve of the window sill is installed in the upper part of the PVC windows, and thereby the air flow enters the room;
• the supply fan unit is installed in a groove on the outer wall.

The only drawback that matters, especially in our climatic zone, is that in the cold season, too cold air can enter the room. This will lead to illnesses and colds, damaged furniture, peeling wallpaper and other unpleasant consequences.

In order for the installation of the supply air ventilation system to comply with the SNiP, which are developed for such cases, a heater is mounted inside, heating the flows to a temperature of at least 18 degrees.

In addition, such an installation includes the mandatory presence of an air filter that can be easily removed and replaced. This protects the incoming air flow from dust, dirt and soot.

The supply air ventilation system must have a high-quality soundproofing.

Due to the fact that the apartments and the house do not have dimensions, monoblock air inlets are most often used for installation. The air handling unit is the most up-to-date compact system, in the main monoblock of which the necessary elements are assembled.

Due to its small size, it can be installed in apartments, on balconies, in small offices, etc. Modern advanced developments allow all commissioning operations to be carried out without specialized experience and skills.

Individual supply ventilation systems

Individual PV, among other technical characteristics, has a capacity of no more than 100 m³\ h, which is why they can be mounted exclusively for one small room. It does not need a specialized complex duct network and does not take up much space. It can also be installed outside the walls, while not disrupting the interior design.

One of the few disadvantages of individual devices is the fact that they are not intended for outdoor use, as well as a high noise level, due to the fact that the housing of the device is characterized by poor sound insulation.

Duct type supply ventilation systems

The duct ventilation system works on the same principle, but with only one difference, air ducts are connected to the inlet and outlet ducts. It is worth clarifying that all supply ventilation, with the exception of individual ones, are of the channel type.

The supply ventilation system in combination with natural ventilation allows you to create a complete system. The most important thing in this matter is the need to correctly place the ventilation equipment, and you also need to correctly install the device and sheath the duct network in the ceiling space. An important factor for the correct operation of the entire system is the location of the ventilation grilles.

The system for cleaning apartments from polluted air must have a capacity of at least 300 m³\ h, for offices the allowed minimum value is 2000 m³\ h.

How to choose a cleaner for apartments

When choosing equipment, there are several parameters that require special attention.

System performance

These parameters are selected based on the design calculated information about the apartment or house, the dimensions of the room are especially important:

• for 1-2 bedroom apartments, a capacity of 200-350 m is provided³\ h;
• for 3-4 room apartments - capacity 350-500 m³\ h.

Static pressure

This characteristic is determined by the length of the air duct network and their configuration features. The pressure in the range of 400-500 Pa is accepted as standard.

Noise level and acoustic power

In any system, the level of acoustic noise is measured not at the input channel, but at the output from the cabinet.

This indicator shows how well the ventilation system will be installed. If the devices of the supply ventilation system provide for installation near a dwelling or directly in an apartment or house. To reduce this indicator, experts advise installing silencers.

System heating power

The required indicator directly depends on the outside temperature, especially in the cold (winter) season. The heating power of the ventilation system is taken as standard in the amount of 3-5 kW.

It should be noted that the calculated power indicator is often much higher than the theoretical load capacity of the air duct network.

By purchasing a cleaner of a lower speed, you can achieve constant maintenance of a comfortable climatic arrangement of the room in the cold season.

Increase the air temperature at the outlet duct, possibly by decreasing the fan speed. However, it is rather inconvenient to do it yourself manually, therefore the purifier is equipped with an automated start-up and adjustment system.

Automatic adjustment

Supply air purification for domestic use should include an integrated commissioning and adjustment system equipped with a screen. The display shows the temperature of the working space, the speed of the system and many other characteristics. Automation greatly simplifies the operation of the ventilation cleaner.

Cleaning the airspace of the premises

Special coarse filters are installed at the inlet of the ventilation system, which protect against large particles of dust, soot, exhaust gases and burning, as well as against animal hair and poplar fluff. To clean the space of the room from fine dust, you will need to install additional filters on your own.

This need is due to the location of the apartment, and the quality of the environment, as well as a number of other factors. When installing an additional thin filter, it is worth knowing that to some extent it reduces the maximum performance of the ventilation system.

Purifier installation location

Considering the options for installing supply ventilation devices, it is necessary to correctly calculate the maintenance methods: replacement of filters, major or emergency repairs, etc. To replace the filters, a service hatch is provided, to which access must be provided.

Air purification system installations

When installing the cleaner, it is worth considering the need to drill mounting holes in the wall outside the building, the holes must be at least 120 mm in diameter. Simple tools that a user has in everyday life cannot cope with such a question; for this, a professional diamond drilling machine is needed. All work of this kind is recommended to be performed before finishing the premises.

Analog home air purifier options

Supply air purifiers consume a lot of electricity, especially during the cold season. For example, if the system capacity is 300 m³\ h, and the operating temperature is brought to 18 degrees, the power consumption will be approximately 4.8 kW \ h. An apartment or a residential building often lacks such capacities and capabilities, therefore, to reduce this indicator, energy-efficient recuperation units of the ventilation system are used.

The peculiarities of installing the purifier in apartments and country houses include the possibility of installing air inlets with a water heater. The principle of operation of such devices is based on heating water circulating through a central or autonomous system.

Before choosing a specific purifier, it is necessary to carefully study all the strengths and weaknesses of each, to understand which device is most acceptable.
