Thermodynamic properties of mixtures of ozone-safe refrigerants FC218-HFC134a and HFC152a-HFC134a.
Author(s) : CHERNYAK Y. A.
Summary
Liquid-vapour equilibria, p,v,T data and critical parameters for FC218-R134a and R152a-R134a systems have been measured using a variable volume apparatus with an optical cell. Original methods have been developed for calculating the saturated vapour density over wide temperature ranges. Thermodynamic efficiency of the mixtures FC218-R134a and R152a-R134a has been estimated on the basis of the vapour-compression cycle.
