AI Technical Summary

Technical Problem

The use of HFO1123 as a working medium in refrigeration cycle apparatuses is prone to disproportional reactions under high-energy conditions, leading to compressor breakdown and soot formation, which can contaminate surrounding components and require costly maintenance.

Method used

A refrigeration cycle apparatus with a compressor housing space defined by a partition plate, a communicating part for soot exhaust, and a pressure relief mechanism to minimize soot dispersal and pressure buildup, along with the use of a disproportionation inhibitor to suppress reactions.

Benefits of technology

Prevents soot from billowing out and reduces the risk of compressor damage, maintaining apparatus reliability and minimizing maintenance costs by securely exhausting soot and suppressing disproportional reactions.
