FIELD: power engineering.
SUBSTANCE: device for air heating of rooms consists of ammonia compressor, heat exchangers, heaters, operated pressure reducing valve, electric motor of air heating, reversible electric motor controlling the pressure reducing valve, thermal relay, air blowers. Ammonia outlet of ammonia compressor of ammonia heat pump is connected to inlet of ammonia-air vapour condensation heater, the outlet of which is connected to inlet of operated pressure reducing valve, the outlet of which is connected to inlet of ammonia-air boiling heater, the outlet of which is connected to inlet of ammonia compressor of ammonia heat pump. Clean ambient air intake device is connected to air-to-air heater, the outlet of which is connected to clean ambient air blower, the outlet of which is connected to air-ammonia heat exchanger, the outlet of which is connected to outlet of heated air nozzle. Air intake device of rooms is connected to air blower of room air, the outlet of which is connected to air-to-air heat exchanger, the outlet of which is connected to inlet of air-ammonia heat exchanger, the outlet of which is connected to outlet of cooled air nozzle. Temperature relay installed in ambient air is connected to reversible electric motor controlling the pressure reducing valve. Temperature relay installed in room air is connected to electric motor of air heating. Electric motor of air heating, ammonia compressor, clean ambient air blower, room air blower - they are all installed on one shaft. There also described is method of air heating of rooms.
EFFECT: supply of environmentally safe heat to rooms and economy of electric energy.
