Exergy Analysis of the Combined Ejector - Vapor Compression Refrigeration System Using R134a as Working Fluid
In the recent years, due to the inevitable deletion of fossil fuels and the requirements of environment protection, the drawback of air conditioner with vapor compressor has become obvious. Recently, scientists are studying refrigeration and air conditioning principles using thermal power such as ejector system or absorption chillers This paper presents a comprehensive investigation of a combined ejector–vapor compression refrigeration system using exergy analysis. The exergy analysis is used to determine various losses from various parts of the system The results show that ejector is the most irreversible part in the system (34.36%). That mean, the optimization of ejector’s geometry to reduce the irreversibility is very important to improve the ejector system performance. Besides, the effect of operating parameters on the exergy loss also researched.
