摘　　要：利用基于Burentt法搭建的高精度压力-体积-温度-组分(PVTx)试验台,测定了混合制冷剂R134a/R600a质量分数为80%/20%和75%/25%、温度为273 K^320 K的PVTx性质。根据测定的数据,拟合了不同质量配比的混合制冷剂相应的气态维里方程。首次研究了该工质的基础热物性,为进一步研究提供详实的数据。The Pressure-volume-temperature-composition （PVTx） properties of mixture refrigerant R134a/R600a with mass faction of 80%/20%and 75%/25%in the range of 273 K-320 K were measured by using high-precision PVTx apparatus which is based on the Burnett method. Based on experimental data, the gas viral equation of mixed refrigerant at different mass fractions was developed. The basic thermal physical property of the refrigerant was investigated for the first time, and the detailed data were provided for the further research.
