An air-conditioning apparatus includes a refrigeration cycle that includes one or more intermediate heat exchangers 15 connected by pipes, the intermediate heat exchanger 15 being 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 21 configured to circulate the heat medium related to heat exchange in the intermediate heat exchanger 15, a use side heat exchanger 26 configured to exchange heat between the heat medium and air related to an air-conditioned space, and flow switching valves 22 and 23 configured to switch between passing the heated heat medium through the use side heat exchanger 26 and passing the cooled heat medium therethrough, the pump 21, the use side heat exchanger 26, and the flow switching valves 22 and 23 being connected by pipes, a ninth temperature sensor 40 configured to detect the temperature of outdoor air, and a controller 60 configured to, when determining during suspension of an operation related to air conditioning that the temperature detected by the ninth temperature sensor 40 is at or below a first predetermined temperature and a first predetermined period of time has elapsed since the pump 21 was stopped, perform control such that the pump 21 is activated to circulate the heat medium through the heat medium circuit. |
