Air-conditioning apparatus
An air-conditioning apparatus includes a refrigeration cycle that includes an intermediate heat exchanger configured to exchange heat between a heat source side refrigerant and a heat medium different from the heat source side refrigerant, a heat medium circuit that includes at least one pump configured to circulate the heat medium related to heat exchange in the intermediate heat exchanger, a use side heat exchanger configured to exchange heat between the heat medium and air related to an air-conditioned space, and flow switching valves. A controller is configured to perform control to activate the pump to circulate the heat medium through the heat medium circuit when, during suspension of an air conditioning operation, the detected temperature of outdoor air is at or below a first predetermined temperature and a first predetermined period of time has elapsed since the pump was stopped..

Heat exchange apparatus and method for controlling heat exchange apparatus
A heat exchange apparatus that exchanges heat between a refrigerant and a temperature-regulated section has: a compressor; a first heat exchanger that exchanges heat between the refrigerant and outside air; a second heat exchanger that exchanges heat between the refrigerant and air for air conditioning; an opening-adjusting valve that adjusts a degree of opening of a path of the refrigerant between the first heat exchanger and the temperature-regulated section; an expansion valve that is disposed in a path of the refrigerant between the temperature-regulated section and the second heat exchanger, and that reduces a pressure of the refrigerant; and an ecu that controls a degree of opening of the opening-adjusting valve. The ecu increases the degree of opening of the opening-adjusting valve to thereby heat the temperature-regulated section, and reduces the degree of opening of the opening-adjusting valve to thereby cool the temperature-regulated section..
