| Abstract: | Based on the Homogeneous Flow Model of adiabatic capillary tubes, a counting program for numerical simulation of the mass flow rate of refrigerant in capillary tubes is developed. The results obtained are compared with the measured data and then analyzed. The investigations include the effects of refrigerant subcooling, capillary length, condensing pressure, evaporating pressure with refrigerants of R12 and R134a respectively on the mass flow rate of refrigerant. |
