Thermodynamic Analysis of R410A Refrigeration Cycle with a Two-Phase Ejector

Article Preview

Abstract:

A thermodynamic analysis of the ejector expansion refrigeration cycle (EERC) was carried out based on a two-phase flow model. First the ejector parameter was optimized under the given condition. Then the influence of condenser temperature and evaporator was investigated. Numerical simulation result shows that the EERC always has a better performance than the basic system. When the evaporator is 0°C, the system COP can be improved by 18.6%.
