Abstract

An ejector refrigeration system is built and water is selected as the working fluid.The effects of operating conditions including the working fluid temperature,evaporation temperature and condensing pressure,and spray structure including constant area section and the area ratio of nozzle throat and the nozzle outlet on system COP are investigated.The results can provide reference for further understanding the working principle of the ejector and improving the performance of the steam ejector refrigeration system.
