摘要： Disclosed herein is a chiller apparatus containing a composition comprising from about 6 to about 70 weight percent 2,3,3,3-tetrafluoropropene and from about 30 to about 94 weight percent 1,1,1,2-tetrafluoroethane. Also disclosed herein are compositions comprising from about 58.0 to about 59.5 weight percent 2,3,3,3-tetrafluoropropene and from about 42.0 to about 40.5 weight percent 1,1,1,2-tetrafluoroethane. Also disclosed herein are compositions comprising from about 54.0 to about 56.0 weight percent 2,3,3,3-tetrafluoropropene and from about 46.0 to about 44.0 weight percent 1,1,1,2-tetrafluoroethane. Also disclosed herein is a composition comprising a refrigerant consisting essentially of from about 58.0 to about 59.5 weight percent 2,3,3,3-tetrafluoropropene and from about 42.0 to about 40.5 weight percent 1,1,1,2-tetrafluoroethane. Also disclosed herein is a composition comprising a refrigerant consisting essentially of from about 54.0 to about 56.0 weight percent 2,3,3,3-tetrafluoropropene and from about 46.0 to about 44.0 weight percent 1,1,1,2-tetrafluoroethane. Also disclosed herein is a method for producing cooling in a chiller. The method comprises (a) evaporating a liquid refrigerant comprising from about 6 to 70 weight percent 2,3,3,3-tetrafluoropropene and from about 30 to 94 weight percent 1,1,1,2-tetrafluoroethane in an evaporator having a heat transfer medium passing therethrough thereby producing a vapor refrigerant; and (b) compressing the vapor refrigerant in a compressor, wherein the volumetric cooling capacity of the refrigerant is greater than the individual volumetric cooling capacities of both 2,3,3,3-tetrafluoropropene and 1,1,1,2-tetrafluoroethane alone. Also disclosed herein is a method for replacing a refrigerant in a chiller designed for using HFC-134a or CFC-12 as refrigerant, comprising charging said chiller with a composition comprising a refrigerant consisting essentially of from about 6 to 70 weight percent 2,3,3,3-tetrafluoropropene and from about 30 to 94 weight percent 1,1,1,2-tetrafluoroethane thereby increasing the cooling capacity of the chiller.
