PURPOSE:To provide a simple construction enabling accumulation of diffused heat and contrive easier manufacture and higher functions by providing a heat pipe one end of which is thermally connected to an outer peripheral surface of an apparatus brought to a high temperature during operation in a refrigerant circuit and the other end of which is thermally connected to a heat-accmulating agent. CONSTITUTION:A first heat pipe 21 filled with an appropriate amount of a refrigerant for transfer of heat is disposed between a heat storage vessel 15 and a compressor 1, and a second heat pipe 22 is disposed between the vessel 15 and an accumulator 3. End parts on one side of the heat pipes 21, 22 are inserted in the heat storage vessel 15 to be capable of heat exchange with a heat-accumulating agent 17, whereas the other end part of the heat pipe 21 is set along an outside peripheral surface of a casing for the compressor 1, and the other end part of the heat pipe 22 for cold heat is set along an outer peripheral surface of the accumulator 3, so as to be capable of heat exchange. During a heating operation, a hot heat ON-OFF valve 23 is kept open, whereby heat diffused from the outer peripheral surface of the casing of the compressor 1 brought to a high temperature is accumulated into the agent 17 in the vessel 15 through the heat pipe 21 for hot heat. |
