AZEOTROPIC OR AZEOTROPIC-LIKE COMPOSITION CONTAINING 1-CHLORO-3,3,3-TRIFLUORO PROPENE AND 1,1,1,3,3-PENTAFLUORO PROPANE

摘要

PROBLEM TO BE SOLVED: To provide a novel refrigerant mixture which can substitute for HCFC123, is a low ODP (Ozone-Deleting Potential) and low GWP (Global Warming Potential) refrigerant, has COP equivalent to that of HCFC123 and has refrigeration capacity and gas density higher than those of a single refrigerants such as HCFO1233zd(E), HFC245fa which are considered as alternative refrigerants for HCFC123.SOLUTION: There is provided a composition containing a refrigerant, and the refrigerant contains HCFO1233zd(E) and HFC245fa with a mass ratio of HCFO1233zd(E) to HFC245fa of 18:82 to 49:51.
