Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/003494
Kind Code:
A1
Abstract:
A refrigeration cycle device (100) according to the present invention uses a non-azeotropic mixed refrigerant. This refrigeration cycle device (100) is provided with a compressor (1), a first heat exchanger (6), a first expansion valve (4A) and a second heat exchanger (3). The non-azeotropic mixed refrigerant is circulated through the compressor (1), the first heat exchanger (6), the first expansion valve (4A) and the second heat exchanger (3) in a first circulation direction. The non-azeotropic mixed refrigerant contains R32, CF3I and R1123. The first weight ratio of the R32 in the non-azeotropic mixed refrigerant that is sealed in this refrigeration cycle device (100) is 43 wt% or less. The second weight ratio of the CF3I in the non-azeotropic mixed refrigerant that is sealed in this refrigeration cycle device (100) is equal to or less than the first weight ratio. The third weight ratio of R1123 in the non-azeotropic mixed refrigerant that is sealed in this refrigeration cycle device (100) is 14 wt% or more.
