Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/214832
Kind Code:
A1
Abstract:
A refrigeration cycle device (100) comprises a refrigerant circuit (RC) and a refrigerant. The refrigerant circuit (RC) has a compressor (1), a condenser (3), a decompression valve (4), and an evaporator (5). The refrigerant is a non-azeotropic refrigerant mixture. At least either the condenser (3) or the evaporator (5) has a first heat exchange unit (C1) disposed on the upwind side and a second heat exchange unit (C2) disposed on the downwind side along a first direction (D1) in which air flows. The first heat exchange unit (C1) and the second heat exchange unit (C2) each have an inflow path (IF) and an outflow path (OF) for the refrigerant, disposed across a plurality of stages, in a second direction (D2) that intersects the first direction (D1). The refrigerant flows from the outflow path (OF) of the second heat exchange unit (C2) to the inflow path (IF) of the first heat exchange unit (C1). In the second direction (D2), the inflow path (IF) of the second heat exchange unit (C2) is disposed in the same stage as the outflow path (OF) of the first heat exchange unit (C1).
