Abstract
An outdoor heat exchanger includes a fan configured to adjust a heat transfer coefficient ao of the outside of a heat transfer tube through which a refrigerant flows, a bypass passage and flow rate control valve configured to adjust a heat transfer coefficient αi of the inside of the heat transfer tube through which the refrigerant flows, and an on-off valve configured to adjust a heat transfer area A where the refrigerant exchanges heat with a heat medium. A controller controls the heat transfer coefficient αo of the outside of the heat transfer tube, the heat transfer coefficient αi of the inside thereof, and the heat transfer area A to control a heat exchange amount of the outdoor heat exchanger.
