Factors influencing performance of ejector based solar energy assisted compression refrigeration system

In order to optimize the systems components matching and controlling, develops a mathematical model, and studies the key factors influencing the performance and characteristics of the system, such as area ratio of nozzles throat and mixing chamber, area of solar energy collector and volume of hot water storage tank. The results show that the area ratio of nozzles throat and mixing chamber of the ejector and the area of solar energy collector greatly impact the operating characteristics and performance of the system, and there are an optimized area ratio of nozzles throat and mixing chamber and an optimized match between the area of solar energy collector and the system. The volume of hot water storage tank does not obviously impact the systems daily refrigerating capacity, but influences the energy saving rate and operating characteristics of the system, and the larger the volume, the higher the energy saving rate.
