Physical Property Models of R32 and POE and PVE Oil
Accurate calculation of refrigerant and oil properties is the foundation to numerical optimization of compressor. The physical properties calculation models of R32 saturation liquid
saturation gas
superheated gas and lubricating oil POE and PVE in the common range are developed based on explicit fitting of the given data. The properties of refrigerant and oil are then analyzed comparatively. These simple and reliable models can lead to shorter simulation time and higher accuracy. The maximum deviations of the predicted values of these models to experiment data are within 5%. These models can be supplied to calculate the mixture physical properties of R32 & POE and R32 & PVE.
