Experimental study on CO2 flow through an electronic expansion valve.

Author(s) : HWANG Y. W., KIM O. J.

Summary

This study reports the experimental results of the mass flow rate of carbon dioxide through the electronic expansion valve (EEV) of which orifice diameters were 1.6 mm and 1.8 mm, respectively. The mass flow rates were measured at various EEV inlet temperatures and pressures for several EEV openings. The EEV inlet temperature was varied from 10 to 40°C at the EEV inlet pressure of 80 and 100 bars, respectively. The mass flow rate of carbon dioxide through the electronic expansion valves ranged from 50 to 120 g/s. The EEV opening and the variation of density around critical point affected the mass flow rate of carbon dioxide. Empirical correlation based on Buckingham pi-theorem was developed and expected the experimental data within an average absolute deviation of 5.4%.
