Calculation Models of Properties of POE/R32and PVE/R32 and the Properties Analysis
The accurate calculation of thermodynamic properties of refrigerant-oil mixture is the foundation to analyze and evaluate the influence of oil on compressor. Thermodynamic property models of R32/POE and R32/PVE are provided by explicit calculation method with the given experimental data and empirical formula. Simultaneously,the solubility and viscosity models of R410A/POE are given with the same method for comparative analysis. The maximum deviation of the predicted values of these models to experiment data is within 5 %,and these simple and reliable models provide accurate and reliable ways for the optimal design and performance analysis of compressors. Besides,the variations of solubility with temperature and pressure
and the variations of viscosity with solubility
temperature and pressure are analyzed at GX condition. In addition,the mixture properties are studied
the results show that PVE oil is better than POE when used with R32
and R32 is better than R410A when used with POE oil.
