Abstract
An air conditioning apparatus includes: a supercooling heat exchanger configured to supercool refrigerant flowing in a first flow path between an outdoor heat exchanger and an expansion valve; a flow path switching valve configured to switch a flow path between an indoor heat exchanger and a compressor to one of a second flow path that does not extend through the supercooling heat exchanger and a third flow path that extends through the supercooling heat exchanger; a bypass circuit that is branched from the first flow path and extends through the supercooling heat exchanger; and a bypass regulating valve provided in the bypass circuit; and a controller. In a cooling operation, when a load is not low, the controller selects the second flow path and opens the bypass regulating valve, whereas when the load is low, the controller selects the third flow path and closes the bypass regulating valve.
