ANVENDELSE TIL OPVARMNING AF KOMBINATIONER AF E-1,3,3,3-TETRAFLUORPROPEN og CHF2CHF2 |
摘要 |
Disclosed herein is a method for producing heating comprising condensing a vapor working fluid comprising (a) E-CF3CH=CHF and (b) at least one tetrafluoroethane of the formula C2H2F4, in a condenser, thereby producing a liquid working fluid; provided that the weight ratio of E-CF3CH=CHF to the total amount of E-CF3CH=CHF and C2H2F4 in the working fluid is from about 0.01 to 0.99. Also disclosed herein is a heat pump apparatus containing a working fluid comprising (a) E-CF3CH=CHF and (b) at least one tetrafluoroethane of the formula C2H2F4; provided that the weight ratio of E-CF3CH=CHF to the total amount of E-CF3CH=CHF and C2H2F4 in the working fluid is from about 0.01 to 0.99. Also disclosed herein is a method for raising the maximum feasible condenser operating temperature in a heat pump apparatus suitable for use with HFC-134a working fluid relative to the maximum condenser operating temperature when HFC-134a is used as the heat pump working fluid, comprising charging the heat pump with a working fluid comprising (a) E-CF3CH=CHF and (b) at least one tetrafluoroethane of the formula C2H2F4; provided that the weight ratio of E-CF3CH=CHF to the total amount of E-CF3CH=CHF and C2H2F4 is from about 0.01 to 0.99. Also disclosed herein is a method for replacing HFC-134a refrigerant in a heat pump designed for HFC-134a comprising providing a replacement working fluid comprising (a) E-CF3CH=CHF and (b) at least one tetrafluoroethane of the formula C2H2F4; provided that the weight ratio of E-CF3CH=CHF to the total amount of E-CF3CH=CHF and C2H2F4 is from about 0.01 to 0.99. Also disclosed herein is a composition comprising from about 10 weight percent to about 40 weight percent E-CF3CH=CHF and from about 90 weight percent to about 60 weight percent CHF2CHF2. |
