Benefits of technology

The present invention provides a composition for a heat cycle system that uses trifluoroethylene (HFO-1123) as a stabilized working fluid. This composition has high cycle performance and low global warming potential, and the system operates efficiently. The technical effects are improved performance and reduced environmental impact.

Problems solved by technology

However, it is pointed out that HFCs may cause global warming.
However, HFO-1123 is a compound having an unsaturated bond in its molecule and is a compound having a very short life in the air, and accordingly under conditions under which compression and heating are repeatedly carried out in a heat cycle, it is inferior in the stability to a saturated hydrofluorocarbon or hydrochlorofluorocarbon such as a conventional HFC or HCFC.
