How to make ventilation in the apartment most effective

Apartment renovation is often not conceivable without installing hermetic plastic windows. Striving for rationality, we choose steel entrance doors with reliable seals, which are almost not subject to temperature and humidity deformations. We insulate and do not ventilate the dwelling in winter, keeping it warm. In this case, we do not think how to make ventilation in the apartment with our own hands.

Why is it dangerous to forget about air circulation

It seems there is nothing wrong with the above. However, the most common in the apartments is forced ventilation, which effectively only works with the free movement of air in all rooms, with the obligatory flow of fresh street traffic.

As a result of all the measures described above, an unhealthy atmosphere is created in the dwelling, and the usual ventilation of the apartments becomes ineffective.

Note! Excess heat combined with excess moisture and slow-moving air are ideal conditions for the growth of pathogenic bacteria, mold and fungi. The air in the apartment becomes stale, and unpleasant smells in it stagnate without finding a way out.

Based on this, the question arises: what to do with poor ventilation in the apartment?

The mechanism of the functioning of ordinary residential ventilation

In apartment buildings, the default type of ventilation works.

1. In any room of the apartment should be carried out constant air exchange: polluted air should be removed, and in its place fresh street flow.
2. In the kitchen, in the toilet and in the bathroom of the dwellings, the exhaust air is removed through the exhaust ducts.
3. Fresh streams seep through open windows, loosely closed doors and windows.

Note! Previously, the natural supply and exhaust circulation system was fully justified. Now, with low efficiency of this method (for the reasons described above), installation of additional ventilation elements is necessary. In other words, the natural ventilation system needs to be replaced with a forced counterpart.

Air exchange rates

Calculate the required supply air volume is quite simple.

1. It is necessary to apply sanitary norms of air exchange in apartments, based on the area of ​​the rooms and the number of tenants.
2. According to the requirements of SanPiN for each m? Do you need air exchange of 3 m? at one o'clock. On one adult person laid 30 m? fresh air per hour.
3. On this basis, it is very simple to calculate the air exchange for a particular dwelling and to design the ventilation system, choosing its optimal type and suitable equipment.

Natural air circulation

Before you make ventilation in an apartment, you should take into account that its simplest method is natural.

When it exhaust air is removed by a natural bastard through the channels of the system, and fresh enters through the vents, windows and doors.

1. To improve the efficiency of this system, additional air flow can be organized through the inlet valves mounted in the windows and walls..
2. An example of such a device is an adjustable vent valve, which is used to equip the sash of window units.. It has a sound-reflecting visor, so it almost does not reduce the noise insulation quality of windows. Installation of the device takes only 15 minutes.

1. Similar valves can be installed in walls, near radiators. To this end, it is necessary to make a through hole in the wall with a section of 5/10 cm, depending on the model of the device.
2. The instruction reminds that the efficiency of the inlet fixtures is dependent on the performance of the exhaust air ducts.

Note! The natural type of ventilation is optimal in winter, when the difference between street and internal temperatures, creating natural cravings, is most noticeable. In the summer, with a difference of less than 15 °, the thrust is not so great.

Forced exhaust ventilation

1. Forced ventilation in the apartment provides exhaust room air mechanically.
2. For this purpose, fans are used that are installed in the ventilation pipes of toilets, bathtubs and electric extracts in kitchens.
3. When the fan is turned on, an air depression is created in the room, which initiates the intake of outdoor air through an open vent or intake valve.
4. If you install forced ventilation in the apartment with your own hands, then in the winter it is recommended to arrange the heating of the incoming air. For this purpose, the supply devices can be equipped with electric heaters.
5. Another option, the price of which will be less, is to place such devices above apartment heaters.

Forced-air ventilation

The principle of operation of the combined supply and exhaust ventilation is the forced supply of outside air through the inlet devices and the pumping out of the exhaust through natural draft through the kitchen and bathroom mines.

The ventilation scheme in the apartment can be implemented with their own hands in different ways, the systems can be of different configurations and models, but they have one device and it includes:

• fan;
• air filter;
• shut-off valve
• heating device;
• sound reflector.

Heating in the winter of outdoor air prevents condensate from settling and mold to multiply in the inlet valve.

To install the system in the apartment, it is necessary to make a hole in the external wall and connect the power supply to the air inlet. In order for ventilation to function better, interior doors must have 1.5 / 2 cm slots at the bottom or small grilles.

Benefits of the Forced System

1. Such ventilation completely mechanizes the air in the apartment.
2. In addition to cleaning and heating outdoor air, heat recovery can also be applied. This will make it possible to reduce heat losses up to 70/80%. The recuperator returns the heat of the exhaust air to the rooms.
3. This device in the summer time significantly reduces the load on the air conditioner, in the winter it makes it possible to conserve heat even during ventilation.
4. The equipment of the system can be installed inside the suspended ceilings or in utility rooms.

Conclusion

By competently installing the ventilation system in the apartment, you will provide yourself and your family with comfortable living conditions at low energy costs. Watch the video in this article. It will help you learn a lot.
