IMPROVED NONAZEOTROPIC WORKING FLUID MEDIA FOR USE IN THERMODYNAMIC CYCLE APPLICATIONS

摘要

A nonazeotropic working fluid medium for use in a thermodynamic cycle system , comprising a mixture of compounds and characterized in that one or more vaporization loss/replenishment cycles of each less than about 15 % of the total weight of the medium and cumulative up to about 50 % of the total weight of the medium result in a total decrease in the coefficient of performance of said medium of no more than about 5 %, or a loss in electric power generating efficiency of not more than about 3 %.
