Refrigerant Forced Circulation Thermal Drive Type Cooling, Heating

摘要

The present invention relates to a refrigerant forced circulation type heat-driven cold, heating combined air conditioner invented to operate by heating the refrigerant by forcibly circulating the refrigerant by the refrigerant flow meter and the refrigerant circulation pump regardless of the installation position of the indoor unit.;An indoor unit 10 comprising an indoor heat exchanger 11 and a blower 12 for cooling and heating the room; Compressor (21), outdoor heat exchanger (22), oil purge valve (23), refrigerant heater (24), combustor (25), cooling valve (26), capillary tube (27), gas-liquid separator (28), four-way valve (31), an outdoor unit (20) composed of a pressure control valve (32) and a check valve (33-36) for preventing refrigerant backflow between each circuit; In the fuel tank 40 for supplying fuel, the air-driven cold / heating air conditioner is configured, and the gas-liquid separator 28 and the indoor heat exchanger are configured such that the refrigerant is forced to circulate so that the heating operation is performed regardless of the installation position of the indoor unit. 11) A refrigerant forced circulation type thermally driven cold, characterized in that the refrigerant flow meter (37) provided between the compressor 21 and the refrigerant inlet port of the gas-liquid separator 28 is provided between the inlet port side. Heating air conditioner.
