Abstract

PURPOSE: For reducing the enclosure amount of refrigerant and preventing the excess and shortage of refrigerant during operation, to make the refrigerant circuit of an air conditioner so that the heat-exchanger not used in operation may be connected to the low-pressure side of said refrigerant circuit.
CONSTITUTION: A check valve 13, a solenoid valve 7, a check valve 16 and a solenoid valve 11 are provided in the circuits interconnecting a compressor 1 on one hand and an indoor heat edchanger 3 and an outdoor heat exchanger 4 on the other through a four-way valve 2, and a three-way valve 12 in the circuit for interconnecting the circuit for interconnecting said four-way valve 2 on one hand and said check valves 13 and 16 and solenoid valves 7 and 11 on the other on one hand and the regenerative heat exchanger 5 of a heat accumulating thak on the other. Upon operation when said regenerative heat exchanger 5 is not used, the refrigerant having accumulated in said regenerative heat exchanger 5 is sucked in the low- pressure side of a piping 31 through making change-over so that said three-way valve 12 may be connected to said regenerative heat exchanger 5, three-way valve 12 and said piping 31.
