Description

<p>R 1132(E), an HFO refrigerant with extremely low GWP and high efficiency, is known to occur self-decomposition reaction by external energy source. In this study, we evaluated the conditions for occurrence of self-decomposition and the discharge energy in compressor for using of R 1132(E) mixed refrigerants. It was found that self-decomposition was less likely to occur as the R 1132(E) concentration decreased, and refrigerants containing R 1132(E) at < 35mass% was stable for excessive discharge energies. The quantification of the discharge energy showed that the energy in 2.2kW compressor was less than 1J. From these results, the composition ratio of R 1132(E) mixed refrigerants which can be used stably as refrigerant were clarified. .It was clarified that these results indicated clarifying the conditions for stable use of R 1132(E) mixed refrigerant.</p>
