A detailed simulation program calculating the performance of solar ejector refrigerant system for comfort air conditioning was presented in this paper. Based on the climatic conditions of xi’an region, the performance of a solar ejector refrigerant system for office building has been analyzed using R717 as refrigerant, the results show that the coefficient of performance (COP) of the system decline in time sequence, and the average COP about the specific days from May to August can arrive to 0.22, 0.12, 0.11, and 0.14. In addition, it is found that solar ejector refrigerant system can provide 13% to 83% heat cooling that the office building needed when the evacuated tube solar collector is 500m2 in xi’an specific days from May to August. The simulation method and results are both a useful reference for the design of solar ejector refrigerant system in xi’an region.
