COMPOSITION COMPRISING 2,3,3,3-TETRAFLUOROPROPENE AND 1,1,1,2-TETRAFLUOROETHANE,CHILLERS CONTAINING SAME AND METHODS OF PRODUCING COOLING THEREIN

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 2ETETRAFLUOROETHANE. ALSO DISCLOSED HEREIN ARE COMPOSITIONS COMPRISING FROM ABOUT 58.0 TO ABOUT 59.5 WEIGHT PERCENT 233,3E 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-TRAFLUOROPROPENE 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-TETRAFIUOROPROPENE 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-TETRAF1UOROPROPENE AND FROM ABOUT 30 TO 94 WEIGHT PERCENT 1,1,1,2-TETRAFIUOROETHANE IN AN EVAPORATOR HAVING A HEAT TRANSFER MEDIUM PASSING THERE THROUGH 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.
