Title:
REFRIGERATING CYCLE DEVICE AND OUTDOOR HEAT EXCHANGER USED IN SAME
Document Type and Number:
WIPO Patent Application WO/2017/221400
Kind Code:
A1
Abstract:
An outdoor heat exchanger (11) of this air-conditioning device (1) is equipped with a main heat exchanger unit (13) and an auxiliary heat exchanger unit (15). When performing operation in which the outdoor heat exchanger (11) functions as an evaporator, in the outdoor heat exchanger (11), refrigerant flows from the auxiliary heat exchanger unit (15) to the main heat exchanger unit (13), and in the auxiliary heat exchanger unit (15), refrigerant flows from a first heat transfer tube (33a) of the auxiliary heat exchanger unit (15a) to a second heat transfer tube (33b) of the auxiliary heat exchanger unit (15b). If the refrigerant outlet temperature is lower than the freezing point of water, operation is performed in such a manner that the temperature of the refrigerant inlet through which refrigerant flows to the auxiliary heat exchanger unit (15) is higher than the outside air temperature, and the temperature of the refrigerant outlet through which refrigerant is fed out from the auxiliary heat exchanger unit (15) is lower than the outside air temperature.
