The invention relates to a power system, in particular for warm air heating systems of the buildings.

Known air heating systems and ventilation systems, where the supply air is heated in water or steam heat exchangers and enters the building /1/.

Also known warm-air heating system, which is the intake device, a fan for moving fresh air, a heat exchanger for prevaricating and ductwork and piping for distribution of heated air circulation /2/.

The disadvantage of these systems is freezing at subzero temperature and low efficiency.

In addition, the well-known air heating system, combined with ventilation, containing intake and exhaust air ducts, fans and heat exchangers and heater pin mounted on the exhaust duct before the heat exchanger frost protection and efficiency /3/.

Object of the invention is the creation of a system of decentralized air heating, combined with ventilation and to prevent freezing of the coolant.

The task is achieved by the fact that the air heating system contains the intake shaft, a fan, a device for heating air supply and exhaust ducts, as a device for heating air system is equipped with a heater mixing type.

The heater is installed between the air intake shaft and fan. The system includes a sensor for measuring the temperature in the working area, transmitting a signal to a controller of the fuel supply.

At the entrance of the heater installed a leveling device for uniform distribution of air flow in his section.

what about the exhaust duct, the leveling device 2, heater 3, the fan 4 and the diffuser 5. The system is equipped with automatic block that allows you to manage the process flow of fuel to the heater depending on the temperature in the working area.

The system works as follows.

Atmospheric air is drawn by the fan 4 through the intake shaft 1 and by means of a blower duct is fed to the heating in the heater 3. Further, the heated air through the diffuser 5 is fed into the working area. At the entrance to the heater 3 is installed a leveling device 2, such as mesh, window blinds, etc., for uniform distribution of air flow in the cross section of the heater, which promotes better combustion of natural gas in the stove.

The system of automatic block allows automatic regulation of fuel flow at a constant volume of air when the temperature in the working area in case of change of the ambient temperature.

The proposed system differs from the known simplicity of construction, compactness and reliability. The system also has the advantage compared with the known re ogliastro air heating by regulating the volume of gas flared.

The system using the heater gas mixing allows you to refuse the application as coolant water exposed to freezing at low ambient temperatures.

The use of heaters with ramp burners utilization of natural gas is almost equal to 100%, because all the heat from the burning gas is transferred directly heated environment.

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.
