Heated ventilation: we will provide housing with clean air

In the course of its work, the intake ventilation forces the outside air into the premises of the building. The simplest mechanical version of such a system is an analogue with a fan mounted in a hole in the wall. It provides a plentiful supply of fresh air. But there is a significant disadvantage - the supply of cold masses in winter.

This can harm the health of the inhabitants of the building and the state of the facing of the premises. As a result, this type of supply systems is usually used only in storage and production facilities.

Note! For effective air exchange in residential buildings, a scheme of forced ventilation with heated air was developed. It is indispensable in the cold season and may additionally include, in addition to warming, cleansing and moisturizing the incoming air masses.

The principle of operation and elements of the system

Such a network may additionally be equipped with some devices.

     What does such ventilation consist of?

1. The element of the ventilation network directly adjacent to the street is an air intake grille.. This part may have different sizes and shapes. It is designed not only to improve the aesthetics of the duct exit, but also protects the system from precipitations, birds, animals, and foreign objects.
2. Next, the flow passes through a special ventilation valve through. It serves to cut off outside air at the time when the system is turned off. Thus, the valve prevents cold flows into the premises in winter. Often this device is equipped with an electric drive, which makes it possible to control it automatically.
3. The next element of the modern intake ventilation system is the filter.. It makes it possible to protect the structure of the network itself, as well as ventilated rooms, from pollution. The most common carbon filters, they should be replaced, as the development.

1. For heating the air in the inlet ventilation meets the air heater.. This device is capable of heating injected flows in winter up to +29 degrees. This device according to the principle of operation can be electric or water.

Note! In an apartment or a small house the best option is to use an electrical counterpart. It is more compact, easy to install and operate. For voluminous residential, public, commercial and other premises, it is better to choose a hot water heater. It is more economical due to the absence of dependence on electricity.

1. To reduce building heat loss and reduce the load on the heater, a recuperator is often used in intake systems.. It warms the incoming outside air due to heat exchange with exhaust exhaust streams.
2. For the discharge of external air in the system meets the fan..
3. It spreads through the rooms through ventilation ducts..
4. The instruction recommends that the ventilation system with a water heater be additionally equipped with a sound absorber.. It reduces the noise level from operating devices.
5. Uniform distribution of supply air is achieved by using diffusers in the ventilation scheme.

     How can the system be managed and controlled?

When the inlet ventilation with air heating with own hands is designed, its scheme can be supplemented with modern devices that will make operation more convenient, comfortable and efficient.

1. With the help of the control panel, it is possible to control and regulate the flow of outside air, as well as its temperature.
2. Some models of PU are equipped with a timer, it allows you to plan actions and give the automation of the ventilation system orders for their implementation on a certain day or even an hour.
3. In addition to the supply fan, the system can be equipped with an exhaust analog. It is desirable that both devices have protection against overheating.
4. It is recommended to purchase a heater with a thermostat, it will prevent the occurrence of a fire.
5. The network can be additionally equipped with a pressure gauge. It will determine the pressure fluctuations (dynamic) flow in the air filter.
6. The shut-off valve is mounted on the inlet branch of the system. Its valve, by means of an electric drive, is automatically lowered when the ventilation is turned off. Therefore, in winter the cold air does not penetrate the premises.

What to consider

1. Modern, full-featured ventilation requires regular maintenance.
2. Due to its complexity, if you are not confident in your capabilities, you should better entrust the installation of the system to specialists.
3. It is not necessary to combine the ventilation network with the installation of air conditioning equipment, for example, an air conditioning system.

Note! Climate control installations only maintain a comfortable temperature in the rooms, and for health, fresh air is always helpful. Therefore, it is better to install supply ventilation with a heater (for winter), and for the summer to provide in its scheme the installation of an air cooler.

Conclusion

If you have the opportunity, install a comprehensive ventilation network in your home. It will not only produce air exchange, but also organizes a comfortable microclimate in the rooms. The price of ventilation will increase, but it’s better not to save on health. The video in this article will complement its theme.
