PROBLEM TO BE SOLVED: To immediately start an air conditioning operation in starting the air conditioning operation. SOLUTION: This air-conditioning hot water supply system 1 includes a refrigerant circuit 10 configured by successively connecting a compressor 11, a hot water supply heating pipe 12 wound around a hot water supply tank 4 in which warm water for hot water supply is stored, an outdoor heat exchanger 14, an electric valve 17 as a pressure reducing mechanism, and an indoor heat exchanger 18 disposed in an air-conditioned room. When a refrigerant recovering operation is performed, an operation of the compressor 11 is started in a state that a close valve 21 at a discharge side of the compressor 11 and close valves 22, 23 at an inlet side and an outlet side of the outdoor heat exchanger 14 are closed, a first bypass circuit 30 connecting a pipe at the discharge side of the compressor 11 and a pipe at the inlet side of the outdoor heat exchanger 14 is opened, and a second bypass circuit 40 connecting the hot water supply heating pipe 12 and the close valve 22, and the indoor heat exchanger 18 and a close valve 24 at a suction side of the compressor 11 is opened. Then the close valve 24 is switched from the open state to a close state. COPYRIGHT: (C)2011,JPO&INPIT
