Title:
REFRIGERATION CYCLE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/004221
Kind Code:
A1
Abstract:
This refrigeration cycle apparatus is provided with a compressor (2), a condenser (3), a decompressing device (4), an evaporator (30), and an internal heat exchanger (50), and performs cooling by circulating a non-azeotropic refrigerant mixture. The evaporator (30) is provided with an upstream heat exchange unit (35) that performs heat exchange between the non-azeotropic refrigerant mixture and an external fluid. The refrigeration cycle apparatus is provided with a downstream heat exchange unit (45) which is disposed downstream of the upstream heat exchange unit (35) and which performs heat exchange between the zeotropic refrigerant mixture and the external fluid. The internal heat exchanger (50) performs heat exchange between the non-azeotropic refrigerant mixture having flown out from the decompressor (4) but having not flown into the upstream heat exchange unit (35) and the non-azeotropic refrigerant mixture having flown out from the upstream heat exchange unit (35) but having not flown into the downstream heat exchange unit (45). Accordingly, the bias of the temperature distribution in the entirety of the evaporator (30) can be reduced.
