Abstract

Saturated liquid densities of the binary refrigerant mixture HFC 152 a (CH₃CHF₂) + CFC 114 (CClF₂CClF₂) were measured along four iso-composition lines, i. e., 10, 20, 50, 80 wt% HFC 152 a, by a magnetic densimeter coupled with a variable volume method using a metallic bellows. The results of forty-four points cover the range of temperatures from 280 K to 390 K. Experimental uncertainties in temperature and density were estimated to be within ±15 mK and ±0.5%, respectively. The results were compared with the modified Rackett equation proposed by Spencer and Danner and the Hankinson-Brost-Thomson equation.
