Performance Prediction of SERS in the supermarket building

A computer program based on existing one dimensional ejector theory has been developed to carry out a study on performance of the system. The performance of solar ejector refrigerant system(SERS) offer air conditioning for supermarket building are predicted under a climatic conditions of zhengzhou region, the results show that the ηsc, COP and μ of the system change in time sequence, and the average COP about the specific days from May to September can arrive to 0.14, 0.15, 0.27, 0.20 and 0.32, and the average ηsc are 0.58, 0.57, 0.53, 0.49 and 0.53, and the average μ are 0.16, 0.17, 0.30, 0.23 and 0.36, respectively. In addition, the results also show that solar ejector refrigerant can provide 41 percent cooling load that the supermarket building needed with 20000m² when the evacuated tube solar collector is 8400m² in zhengzhou specific days from May to September during the hours(8:00∼18:00).
