The ventilation system contributes to the creation of favorable conditions and the microclimate necessary for human life. That is, the air environment with the desired temperature, humidity, pressure and air composition. Ventilation is natural, mechanical and mixed.
Natural ventilation is characterized by the penetration of air into the room through the cracks in the window and door openings, an open window, ventilation grilles installed on the roofs of deflectors, creating a traction for the removal of air from apartments. The lack of such ventilation is that the room includes contaminated air of the environment.
Based on the belonging, the functional orientation of the room, the current air renewal standards are calculated: for rooms-1 air exchange per hour, for kitchens-at least 3, for chicken-at least 10. That it is not enough to provide these requirements of natural ventilation. Therefore, they install mechanical fans in the kitchen, in the bathroom and bathroom.
There are fans that respond to increasing the permissible level of humidity, as well as those that are connected to the light switch, and finally – with a forced inclusion system. To ensure the influx of fresh air in the walls, windows or their accessories, the supply valve is built. Reducing noise and cleaning the incoming air is provided by special arrangements and filters.
Forced air exchange is provided by mechanical ventilation systems.
The channel fan, passing air through filters and an air heater, supplies it to the air duct, where special grille distributes it throughout the room.
There is also an supply ventilation installation, which is installed on the balcony, in the pantry, bathroom. The role of supply and exhaust monoblock installation is to clearly ensure the frequency of air exchange. The gearbox provides air at the expense of the remote air, which allows you to reduce the energy consumption of ventilation to 90%.
In the kitchen, you can install a local ventilation system, which will remove contaminated air locally, for example, above the kitchen stove.
