| Abstract | ||
| In this paper adiabatic flow in capillary tube is analyzed and modeled for R-22 and alternative R-407C. The equations of continuity, energy and pressure drop through a capillary tube are presented. A mathematical model of sub–cooled flow region and two–phase flow region is developed. The results of the calculation compared with experimental data presented in the technical literature will be shown in the present article in order to validate the model developed. This numerical model is capable of providing an effective means to analyze capillary tube performance to optimize and control an R – 22 and R – 407C in an air – conditioning systems. | ||
