Abstract: A mathematical model of adiabatic refrigerant flow through capillary tubes is presented. When using this model for R22, Chen et al.' s metastable model was improved by a correction factor related to Reynolds number. The resulting model can predict most of the experimental data for R22 within ±5%. For R134a, with the original metastable correction, the model predicted most of the experimental data with ±6% except that having subcooling less than about 5°F.
