On the Prediction of Joule-Thomson of Refrigerants at Low Pressure

In this paper, Joule-Thomson coefficient at low pressure for refrigerant fluids are predicted in order to evaluate the performance of their correlation function. The studied refrigerants are R۱۱, R۱۲۳, R۱۲۴, R۱۳۴a, R۱۴۳a, R۱۵۲a, R۱۴۱b, R۱۴۲b, R۲۲۷ea and R۲۳۶ea. The studied corresponding state principle is the one suggested by Meng et al. In addition, to compare with the data obtained by others, Boyle temperature, Boyle volume and maximum inversion temperature were also calculated using the correlation. The obtained results show that the correlation equation presented has a good ability to predict the thermophysical properties of materials over a wide range of temperatures.
