The PVTx properties of the refrigerant mixtures of R1234yf and R152a with a mass fraction of R1234yf from 0.600 to 0.900 were measured using the method of Burnett’s isothermal expansions. The temperature range was from 288.15 to 328.15 K with a temperature interval of 10 K. The standard uncertainties of the experimental setup were estimated to be 8.1 mK for temperature and 1.73 kPa for pressure. The relative uncertainties were 0.0008 for the compressibility factor and 0.006 for density. According to the obtained experimental data of densities and compressibility factors for the mixtures, gaseous virial equations of state and their second and third virial coefficients were fitted. This would be helpful for the use of R1234yf/R152a mixtures as new environmentally friendly refrigerants.

二元 R1234yf/R152a 制冷剂 PVTx 特性的实验研究

使用伯内特等温膨胀法测量了R1234yf 和R152a 的制冷剂混合物的PVTx特性,其中R1234yf 的质量分数从0.600 到0.900。温度范围为 288.15 至 328.15 K,温度间隔为 10 K。实验装置的标准不确定度估计为温度 8.1 mK 和压力 1.73 kPa。压缩系数的相对不确定度为 0.0008,密度的相对不确定度为 0.006。根据得到的混合物的密度和压缩因子的实验数据,拟合了气体维里状态方程及其第二和第三维里系数。这将有助于将 R1234yf/R152a 混合物用作新型环保制冷剂。
