FIELD: heating.
SUBSTANCE: system of premises air heating with application of atmospheric air heat, which consists of electric motor, ammonia compressor, radiators, heat exchangers of reduction valve, blowers and heat relays. Outlet of ammonia compressor is connected to the inlet into ammonia-air radiator of ammonia vapors condensation, the outlet of which is connected to controlled reduction valve, the outlet of which is connected to the inlet into ammonia-air radiator of ammonia boiling, the outlet of which is connected with the inlet into ammonia compressor. Heat relay of connection and disconnection of reversible electric motor of reduction valve control, which is installed in the atmospheric air from the external side of the premises, is connected to reversible electric motor, which is connected with controlled reduction valve. Atmospheric air intake is connected with the inlet to centrifugal blower, the outlet of which is connected to the inlet into air-ammonia heat exchanger, the outlet of which is connected to the outlet nozzle of cooled atmospheric air. Intake of heated premises air is connected to the inlet into centrifugal blower of heated premises air, the outlet of which is connected with inlet into air-ammonia heat exchanger of premises air heating, the outlet of which is connected to the outlet nozzle of heated air. Heat relay of connection and disconnection of electric motor is connected to electric motor. Electric motor, ammonia compressor, centrifugal blower of atmospheric air, centrifugal blower of heated premises air - all are installed at single shaft. Also method of above described system operation is specified.
EFFECT: saving of fuel used for premises heating.
