REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/249394
Kind Code:
A1
Abstract:
A refrigeration cycle device (100) comprises: a refrigerant circuit (80); and a non-azeotropic refrigerant, which flows through refrigerant pipes (51-56). When the non-azeotropic refrigerant passes through an outdoor heat exchanger (40), a temperature difference occurs between an inlet and an outlet of the outdoor heat exchanger (40). The outdoor heat exchanger (40) comprises: fin groups (L1, L2), which are stacked with spaces therebetween; and heat transfer tubes (R1-R12), which pass through the fin groups (L1, L2) in the stacking direction of the fin groups (L1, L2) and through which the non-azeotropic refrigerant flows. The fin groups (L1, L2) comprise: a first fin portion (A1) to which frost can adhere in a humid environment, and a second fin portion (A2) to which frost does not adhere and for which ventilation is ensured.
