| titleOfInvention | Compositions comprising 2,3,3,3-tetrafluoropropene and 1,1,1,2-tetrafluoroethane, chillers containing them, and methods for producing cooling therein |
| abstract | A composition comprising about 6 to about 70 weight percent 2,3,3,3-tetrafluoropropene and about 30 to about 94 weight percent 1,1,1,2-tetrafluoroethane A chiller device containing the same is disclosed. A composition comprising about 58.0 to about 59.5 wt% of 2,3,3,3-tetrafluoropropene and about 42.0 to about 40.5 wt% of 1,1,1,2-tetrafluoroethane Also disclosed. A composition comprising about 54.0 to about 56.0 wt% of 2,3,3,3-tetrafluoropropene and about 46.0 to about 44.0 wt% of 1,1,1,2-tetrafluoroethane Also disclosed. Herein, the present invention consists essentially of about 58.0 to about 59.5% by weight of 2,3,3,3-tetrafluoropropene and about 42.0 to about 40.5% by weight of 1,1,1,2-tetrafluoroethane Also disclosed are compositions comprising a refrigerant. Herein, it is essentially composed of about 54.0 to about 56.0 weight percent of 2,3,3,3-tetrafluoropropene and about 46.0 to about 44.0 weight percent of 1,1,1,2-tetrafluoroethane Also disclosed are compositions comprising a refrigerant. Also disclosed herein is a method of producing cooling in a chiller. The process comprises (a) about 6 to 70 wt% of 2,3,3,3-tetrafluoropropene and about 30 to 94 wt% of 1,1,1 in an evaporator having a heat transfer medium therethrough Generating a vapor refrigerant by evaporating a liquid refrigerant comprising, 2-tetrafluoroethane; And (b) compressing the vapor refrigerant in the compressor, wherein the volumetric cooling capacity of the refrigerant is both 1,1,1,2-tetrafluoroethane and 2,3,3,3-tetrafluoropropene alone. In excess of all individual volume cooling capacities). Herein, in a chiller designed to use HFC-134a or CFC-12 as a refrigerant, about 6 to 70% by weight of 2,3,3,3-tetrafluoropropene and about 30 to 94% by weight of 1,1 Also disclosed is a method of replacing a refrigerant in said chiller, comprising increasing the cooling capacity of the chiller by introducing a composition comprising a refrigerant consisting essentially of 1,2-tetrafluoroethane. |
