Abstract (en)
[origin: EP3477227A1] An outdoor heat exchanger (11) of an air conditioning apparatus (1) includes a main heat exchange unit (13) and an auxiliary heat exchange unit (15). When the outdoor heat exchanger (11) is operated to function as an evaporator, in the outdoor heat exchanger (11), refrigerant flows from the auxiliary heat exchange unit (15) into the main heat exchange unit (13), and in the auxiliary heat exchange unit (15), refrigerant flows from a first heat transfer tube (33a) of an auxiliary heat exchange unit (15a) into a second heat transfer tube (33b) of an auxiliary heat exchange unit (15b). When a refrigerant outlet temperature is lower than a freezing point of water, the operation is performed such that a refrigerant inlet temperature of the refrigerant flowing into the auxiliary heat exchange unit (15) is higher than an outdoor air temperature and that a refrigerant outlet temperature of the refrigerant delivered out of the auxiliary heat exchange unit (15) is lower than the outdoor air temperature.
