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 *** 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℃.
