摘　　要：本文以Burnett法为基础搭建了高精度压力-体积-温度-组分(PVTx)实验台,在温度为(253~313)K时,测定了质量分数为15%/85%和25%/75%混合制冷剂R1234yf/R32的PVT性质,获得了该混合制冷剂R1234yf/R32详实的热物性数据,并与Refprop9.0中相对应的数据做出比较,发现误差较小,实验数据可靠,为目前正在进行的制冷工质替代研究提供了重要的参考。Based on the Burnett method,a high precision pressure-volume-temperature-component(PVTx)testbench was built.Under the temperature of(253~313)K.The PVT properties of mixed refrigerant R1234yf/R32with mass fraction of15%/85%and25%/75%were determined,and the detailed thermophysical properties of themixed refrigerant R1234yf/R32were obtained.Compared with the corresponding data in Refprop9.0,it is foundthat the error is smaller and the experimental data are more reliable.It provides an important reference for thecurrent research on alternative refrigerants.
