Résumé

In this paper, experimental data and a model for predicting refrigerant flow through orifice tubes used as expansion devices in automotive and other air conditioning systems are presented. The results are analyzed for an extensive set (933 data points) of measurements of mass flow rate of refrigerant R134a through orifice tubes of different diameters and lenghts, with and without inlet and outlet screens, over a wide range of operating conditions, and in the range of inlet qualities from 0 to 1 and subcooling up to 40 °C.
