摘要： In a heat pump apparatus, it is aimed to enhance efficiency of a defrost operation by reducing a loss of heat radiation during the defrost operation and reducing a compressor input during the defrost operation. The heat pump apparatus includes a main refrigerant circuit in which a compressor, a first heat exchanger, an expansion mechanism, and a second heat exchanger are connected sequentially, and also includes a bypass circuit including an on-off valve and providing a connection by bypassing the expansion mechanism. The main refrigerant circuit includes a four-way valve that switches between a heating operation and the defrost operation by switching an order in which the refrigerant circulates through the main refrigerant circuit. The main refrigerant circuit also includes a first temperature detection unit and a second temperature detection unit. Based on values detected by these temperature detection units, a degree of superheat of the first heat exchanger during the defrost operation is computed. When the heating operation is switched to the defrost operation, the heat pump apparatus increases a circulation amount of the refrigerant circulating through the refrigerant circuit by opening the on-off valve, and also controls an operation frequency of the compressor such that the degree of superheat is at a predetermined target value.

摘要： An air-conditioning system includes a pump that sends, to an evaporator, a cooling fluid that exchanges heat with a refrigerant at the evaporator, and a first heat exchanger that exchanges heat between ambient air and the cooling fluid that has undergone the heat exchange at the evaporator. A sensible heat exchange cycle is formed by annularly connecting the evaporator, the heat exchanger, and the pump by using a pipe. This system is also includes an air-sending unit that sends air to a second heat exchanger, moisture absorbing-and-desorbing devices that are provided at a passage of the air sent by the air-sending unit and that are disposed in front of and behind the first heat exchanger, and an air-path switching device that reverses a passing direction of air passing through the moisture absorbing-and-desorbing device, the first heat exchanger, and the moisture absorbing-and-desorbing device.
