Abstract
An air conditioner includes a heat source unit having a compressor, a first heat exchanger configured to cause heat exchange between a refrigerant and liquid fluid, a second heat exchanger configured to cause heat exchange between the refrigerant and air, and a valve configured to switch to supply or not to supply the second heat exchanger with the refrigerant, and a controller configured to control to operate the compressor and to open or close the valve. The controller opens the valve to supply the second heat exchanger with the refrigerant to cause the second heat exchanger to function as a heat absorber when assessing that the refrigerant sent to the utilization unit needs to be decreased in quantity during cooling operation in which the first heat exchanger functions as a radiator.
