COMPOSITION CONTAINING REFRIGERANT AND APPLICATION OF SAID COMPOSTION

Document Type and Number:

WIPO Patent Application WO/2018/194113

Kind Code:

A1

Abstract:

The present invention provides a composition containing a refrigerant that, relative to R404A (R125/R134a/R143a = 44/4/52 wt%), has equivalent incombustibility and substitutable refrigeration capacity, and is also endowed with performance such that the COP is equivalent or greater and the GWP is 1500 or less. The present invention, specifically, provides a composition containing a refrigerant wherein the refrigerant contains a mixture of fluorinated hydrocarbons; the mixture contains difluoromethane (R32), pentafluoroethane (R125), and 1,1,1,2-tetrafluoroethane (R134a) in specific concentrations; the fluorinated hydrocarbons included in the mixture have a specific composition ratio; and the composition can be used as a substitute refrigerant for R22 or a substitute refrigerant for R404A.
