摘要
A group contribution method is designed for the estimation of basic properties(normal boiling poillt, critical temperature and critical pressure) of new heat pump working fluids.The average relative errors of the proposed method for estimating Tb, Tc and Pc are 1.29%,1.31% and 2.38% respectively. As a result of the application of the method, 14 stratospherically safe heat pump working fluids are selected as alternatives of Rll4 when the condensing temperature is about 80℃.
