FIELD: heating systems.
SUBSTANCE: heating and ventilation system consists of suction-and-exhaust ventilation, infrared light gas-burner with a heat exchanger-recuperator and central heat exchanger-recuperator of waste heat. On places inhabited by animals, a light gas-burner is installed. The upper part of the reflectors where the heat exchanger-recuperator is installed is connected to the hot channel of the central heat exchanger-recuperator of waste heat and an exhaust blower. Clean cold air through the central heat exchanger-recuperator of waste heat pumped into the input of the inlet fan, and from the output, it passes through a duct to the input of the cold channel of the heat exchanger-recuperator of the light gas burner and through the output, it passes through a duct to the place inhabited by animals. The control process of burning the light gas-burner is achieved using a temperature sensor, installed in the burning zone. The signal from this sensor is passed on to the first comparator unit, which implements the program algorithm for controlling burning. Temperature in the zone where animals can be found is controlled by a temperature sensor installed in the zone inhabited by animals. The signal from this sensor is used by the second comparator unit to implement a program algorithm for controlling a pneumatic valve, which controls flow of gas in the burner. Through the third comparator unit, the temperature control sensor for incoming air controls the valves and implements program algorithm for inletting air. Freezing temperature of the moisture on the walls of the outlet channel of the central heat exchanger-recuperator of waste heat is controlled by a temperature sensor. The signal from this sensor is used by the fourth comparator unit to implement a program algorithm for freezing through switching off the fan for the inlet channel or reduction of flow of the incoming air. The signal also controls the valves in the burner supplied with air.
EFFECT: invention allows for making an energy conserving decentralised heating and ventilation system.
