Title
(EN) WORKING MEDIUM FOR REFRIGERATION CYCLE, AND REFRIGERATION CYCLE SYSTEM
(JA) 冷凍サイクル用作動媒体および冷凍サイクルシステム
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a working medium for refrigeration cycle capable of effectively suppressing or lessening disproportionation reactions even if under a higher temperature condition when using simultaneously 1,1,2-trifluoroethylene and difluoromethane.

SOLUTION: The working medium for refrigeration cycle includes: (A) 1,1,2-trifluoroethylene; (B) difluoromethane; and (C) a halo-alkane, that is a disproportionation depressant, (provided that the carbon number is 1-4, and except for the case that all halogen atoms are fluorine atoms), where, in a 3 constituent composition diagram expressing a mass ratio composition of the constituents by a triangular diagram, (A)-(C) constituents are within a composition range corresponding to a combining region constituted by a first overlapping region of overlapping a region a ((A) constituent of more than 0 mass% and 65 mass% or less) with a region b ((B) constituent of more than 0 and 30 mass% or less), and a second overlapping region of overlapping a region c ((C) constituent of 20 mass% or more and less than 100 mass%) with the region b.
