Title:A Theoretical Model for Predicting Adiabatic Capillary Tube Performance: An Analysis and Improvement
Author(s):Yin, J.M.
Subject(s):stationary air conditioning system analysis
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.
