Abstract

PURPOSE: To increase endothermic amount so as to minimize return of liquid to a a compressor by providing a first gas-liquid separator built in a heat exchanger for heating and a second gas- liquid separator communicating to the first one through at least two pipes on the upper and lower portions to mount a temperature feeling portion of an expansion valve in the upper communicating pipe.
CONSTITUTION: Refrigerant which flows into a first gas-liquid separator 11a from an inlet pipe 12 is separated into gas and liquid. The liquid refrigerant flow into a second gas-liquid separator 12b through the lower communicating pipe 16, and gas refrigerant is made superheated gas by a heat exchanger 13 for heating and flows into the second gas-liquid separator 11b through the upper communicating pipe 15. The degree of superheat of refrigerant at the outlet of heat source side heat exchanger 4 and the region of superheated gas become null due to the effect of heating refrigerant to increase heat exchanging area and endothermic amount. When the liquid refrigerant flows into the gas-liquid separator 11a in plenty due to the drop of the atmospheric temperature, the heat exchanger 13 for heating has more liquid refrigerant immersed portions to reduce the heating amount and the degree of superheat of gas refrigerant. This is sensed by a temperature feeling portion 5a to close the expansion valve 5.
