Abstract: With analysis on the solar ejector cooling system and comparison with the common refrigerants, a new refrigerant of R236fa to the solar ejector cooling system was suggested. The operation of the ejector cooling system was simulated with a mathematical model. In order to verify the theoretical simulation, an experimental study of the system using refrigerant R236fa, R141b and R123 was carried out with the evaporator temperature (5-10°C), condenser temperature (30-36°C) and generator temperature (82-94°C). It was found that the optimum COP (=0.413) of the ejector cooling system, the optimum COPsc(=0.243) and cooling capacity (=11.90 kW) of the overall solar ejector cooling system could be obtained in the system using refrigerant R236fa.
