Study on the Hourly Performance of A Solar Driven Ejector Refrigerant System

Abstract

Abstract-An experimental setup about solar ejector refrigeration is designed and built using HFC134a as working fluid in this paper. Based on Zhengzhou meteorological parameters, the hourly coefficient of performance(COP), energy efficient ratio(EER), cooling capacity and other parameter about the ejector refrigeration system have been researched with the solar radiation changed, The experimental data show that the hourly COP and EER of the system change constantly, and it has been influenced by the solar radiation, the ambient temperature, generator temperature, and condenser temperature et al., and the cooling capacity, heat transfer capacity about the exchanger, and generator temperature appear rise and fall in the research range. The average daily COP is 0.18 at the July 26, the average EER can up to 3.5.
