Abstract

This study aims to design the two-phase flow ejector and to evaluate the Coefficient of Performance of ejector expansion refrigeration system. A mathematical model is developed to analyze the relationships among the operating conditions with the ejector sizes and the system COP, respectively. In this study, the refrigeration system having 3.5 kW of capacity is operated with condenser and evaporator temperature ranging from 35–55°C and 0–15°C, respectively and R32 is used as the working fluid. From the results, it was that varying the operating conditions strongly affects the required ejector sizes and the system COP. In addition, the relationships obtained from this study can be used as a guideline to design the ejector expansion refrigeration system.
