Ventilation Supply and Exhaust

Supply and exhaust ventilation is one of the forms of mechanical ventilation, in which the supply of clean air and the extraction of contaminated (used) air are carried out simultaneously and, as a rule, are coordinated in volume. This system is used in buildings to maintain optimal levels of air exchange, which is important for maintaining the health and comfort of people inside the building.

The basic principle of supply and exhaust ventilation is the supply of fresh air into the room and the simultaneous removal of polluted air outside. For this purpose, a system of supply and exhaust ventilation devices is used, which can be either central or distributed throughout the building.

Supply units are responsible for supplying fresh air to the room. They can be equipped with filters that remove dust particles, pollen and other pollutants from the air. Exhaust devices, in turn, are responsible for removing contaminated air from the room and discharging it outside.

One of the main advantages of supply and exhaust ventilation is the ability to control the air quality in the room. This system allows you to maintain a constant flow of fresh air, which is especially important in buildings with low ventilation and a high degree of indoor pollution.

In addition, supply and exhaust ventilation helps reduce heating and air conditioning costs, since fresh air entering the room already has temperature and humidity parameters closer to the required ones than outside air.

In conclusion, we can say that supply and exhaust ventilation is an effective and economical solution for ensuring comfortable living and working conditions in buildings. It allows you to maintain optimal levels of air exchange and control indoor air quality, which is an important factor for the health and well-being of people.



Supply and exhaust ventilation. Supply and exhaust ventilation systems provide fresh air into the room and exhaust air out. A properly designed and installed supply and exhaust ventilation system creates a favorable microclimate and has a positive effect on people’s health and performance. Conducted assessments of the parameters of the airspace of buildings show that the excess of the concentration of carbon dioxide, the maximum permissible concentration, can be on average from 2 to 6 times for each specific room. If the sanitary standard for CO2 content is about 0.03%, then with a significantly increased concentration the level of carbon dioxide can be several times higher than normal. The main components that allow air to pass through rooms (exchange) are the main building spaces, air ducts and ventilation equipment. Most supply systems use special ventilation equipment. The equipment can be implemented in two versions: supply chambers and air conditioners (monoblock systems) or fans (unheated system). The ventilation system kit includes a supply and exhaust unit (a piece of equipment that supplies air from the street, purifies it and heats or cools it), an air duct (a channel through which air is transported from the installation to the point of supply), a fire grille (a grille to protect against unwanted visitors) and an air inlet (outlet) valve (a device that closes the channel if there is no air supply or outlet and forms a gap opposite the air ducts when installation
