Abstract

Provided is a refrigeration device in which a refrigerant circuit (10) comprises a discharged refrigerant recovery receiver (41) and a discharged refrigerant relief mechanism (43, 44, 45). The discharged refrigerant recovery receiver (41) branches and is connected between the discharge side of a compressor (21) and the gas side of radiators (23, 31) via a discharged refrigerant branch pipe (42). The discharged refrigerant relief mechanism (43, 44, 45) is provided to the discharged refrigerant branch pipe (42) and connects the discharge side of the compressor (21) with the discharged refrigerant recovery receiver (41) when the refrigerant on the discharge side of the compressor (21) causes a disproportionation reaction or when said refrigerant satisfies a predetermined condition before causing a disproportionation reaction.

Description

technical field [0001] The present invention relates to a freezing device. Background technique [0002] At present, in order to prevent the destruction of the ozone layer, HFC-32 (difluoromethane) or a mixture of HFC-32 and HFC-125 (pentafluoroethane) is used as a refrigerant enclosed in the refrigerant circuit of the refrigeration unit. 410A etc. However, the above-mentioned refrigerants have a problem that their GWP (Global Warming Potential) is large. [0003] In contrast, it is known that the refrigerant containing HFO-1123 (1,1,2-trifluoroethylene) disclosed in Patent Document 1 (National Publication No. 2012 / 157764) has an influence on the ozone layer and global warming smaller. In addition, Patent Document 1 discloses that the above-mentioned refrigerant is enclosed in a refrigerant circuit to constitute a refrigeration device. Contents of the invention [0004] However, the refrigerant disclosed in Patent Document 1 has a property that a disproportionation rea...
