R32和R32/R1234yf混合工质黏度实验测量及模型
Viscosity Measurements and Modeling for R32 and Binary Mixture of R32/R1234yf
摘要
Abstract
There is current interest in developing working fluids with low global warming potential (GWP).One such fluid is 2,3,3,3-tetrafluoroprop-1-ene (R1234yf).Although the thermophysical properties are critical for the selection of the potential refrigerant,only a few studies have been conducted on the thermophysical properties of refrigerant mixtures containing R1234yf.In this work,we focused on the viscosity of R32 and the binary mixture of R32/R1234yf.The liquid viscosity of R32 and binary mixture of R32/R1234yf were presented over the temperature ranges of (263 to 350) K and (263 to 360) K at pressures up to 30 MPa using the vibrating wire viscometer.The measurements of mixtures containing the mole fraction (0.244 8,0.410 8,0.608 6 and 0.835 6) of R32 were carried out.The overall uncertainties of these resudts were + 2.0 ％.The experimental results of the pure R32 and the mixture were correlated with hard-sphere scheme.The average absolute deviations between the experimental results and the correlations were 0.28 ％ for R32 and 0.69 ％ for R32/R1234yf,and the maximum absolute deviations were 0.92 ％ and 2.09 ％,respectively.Comparisons between measurements of this work and literatures were also presented.关键词
