Abstract

An air conditioner (100) includes a refrigerant circuit (Q) configured such that refrigerant sequentially circulates in a refrigeration cycle through a compressor (31), a condenser, an outdoor expansion valve (34), and an evaporator, and a control unit configured to control at least the compressor (31) and the outdoor expansion valve (34). One of the condenser or the evaporator is an outdoor heat exchanger (32), and the other one of the condenser or the evaporator is an indoor heat exchanger (12). The control unit causes the indoor heat exchanger (12) to function as the evaporator, and an indoor fan (14) to rotate backward during the freezing processing of freezing the indoor heat exchanger (12).
