近共沸制冷剂R134a/R1234yf的PVTx性质的实验研究
Experimental Study of PVTx Properties of Near Aeotropic Mixture Refrigerant R134a/R1234yf
摘要
Abstract
In order to obtain the thermophysical properties of mixture refrigerant R134a/R1234yf, the PVT properties of mixture refrigerant R1234yf/R134a with mass fraction 40%/60%, 65%/35%,60%/40% in the range of 268 K~323 K were measured by using high-precision PVTx apparatus which is based on the Burnett method, and the gas virial equation of these mixed refrigerants was fitted based on the measured data. The average error between experimental data and equation is about 1%. It turned out that the experimental data agreed well with the equations, which provides the basis for further research on the liquid-vapor equilibrium characteristics for the mixed refrigerant of R134a/R1234yf.关键词
