| Abstract: | The adiabatic flow in capillary tube was analyzed and modeled for R407C, which is a nonazeotropic mixed refrigerant and one of the promising alternatives to R22. The equations of energy, continuity and pressure drop through a capillary tube were presented. A mathematical model of the subcooled flow region and the two phase flow region was developed. Compared with R22, the calculation results show that this numerical model is capable of providing an effective means to analyze components' performance in optimizing and controlling R407C air conditioning systems. |
