USE OF E-1,1,1,4,4,5,5,5-OCTAFLUORO-2-PENTENE AND OPTIONALLY 1,1,1,2,3-PENTAFLUOROPROPANE IN CHILLERS
摘要
This invention relates to method for producing cooling in a chiller having an evaporator wherein a refrigerant composition is evaporated to cool a heat transfer medium and the cooled heat transfer medium is transported out of the evaporator to a body to be cooled, wherein said chiller is a centrifugal chiller. The method comprises evaporating a composition comprising E-HFO-1438mzz and optionally HFC-245eb as a refrigerant composition in the evaporator. This invention also relates to a composition comprising: (1) a refrigerant component consisting essentially of HFC-245eb and E-HFO-1438mzz; and (2) a lubricant suitable for use in a chiller; wherein the E-HFO-1438mzz in the refrigerant is at least 1 weight percent. This invention also relates to a centrifugal chiller apparatus containing a refrigerant composition, characterized by said refrigerant comprising E-HFO-1438mzz and optionally HFC-245eb.
