Experimental Study on an Ejector Refrigeration System Driven by Solar Energy for the Specific Climate Condition

For the specific climate condition, An experimental setup is designed and built to study ejector refrigeration system performance using HFC134a as working fluid in this paper. The experimental data demonstrate that the hourly COP and cooling capacity of the system vary with the solar radiation and the ambient temperature; in addition, the time-averaged COP of the system at the specific climate condition can reach at 0.14, 0.17 and 0.19, and the average cooling capacity can reach to 2.8kW, 3kW and 3.3kW when the hour varied between 9:00 and 16:00 on 19th, June, 26th, July and 18th, August, respectively.
