Title:
WORKING MEDIUM FOR HEAT CYCLES, COMPOSITION FOR HEAT-CYCLE SYSTEMS, AND HEAT-CYCLE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/141678
Kind Code:
A1
Abstract:
Provided are: a working medium for heat cycles which has a low impact on global warming, a low temperature gradient, and a sufficiently low discharge temperature, and which exhibits excellent cycle performance (i.e. refrigeration capacity and coefficient of performance); a composition for heat-cycle systems; and a heat-cycle system. The working medium for heat cycles includes trifluoroethylene and 1, 2-difluoroethylene. Also provided are: a composition for heat-cycle systems; and a heat-cycle system which uses the working medium and the composition. It is prefereable that, in the working medium for heat cycles, the ratio of the total amount of trifluoroethylene and 1, 2-difluoroethylene be at least 20 mass%, and equal to or less than 100 mass%.
