AIR CONDITIONING DEVICE

摘要

To provide an air-conditioning apparatus capable of achieving energy saving. Pump control of controlling the operating capacity of a pump 21 is performed such that the opening degree of a heat medium flow control device 25, controlled by control of the heat medium flow control device, approaches a target opening degree, and a refrigeration cycle as a refrigerant circuit is controlled such that the temperature of a heat medium, whose flow rate is controlled by the control of the heat medium flow control device and the pump control, approaches a target temperature.
