Performance and Optimization Study of Solar Ejector Refrigeration System with Multiple-Ejectors
摘要
Abstract
Based on the multiple-ejectors of the solar ejector refrigeration system,an operation plan,namely injectors witching,was put forward in which the nozzle is constant,and the size of the spray cooling mixing chamber in the injector is changed.The TRNSYS simulation software was used to simulate the multi-ejector solar ejector refrigeration system and the single ejector re-frigeration system in the typical summer weather and the optimization of the number of ejector in the ejector refrigeration system was set up,The results show that the solar ejector refrigeration system with the multiple-ejectors is superior to the single ejector refrigeration system.The former has a larger hourly refrigerating capacity,the total refrigerating capacity in a day is 15.3% higher than that for the latter;The former has a higher system COP,about 10% higher than that for the latter;The former has a running time one and a half hour longer than the latter.The optimal num-ber of the ejector is three,giving an overall refrigerating capacity about 2.8% larger and the sys-tem COP,about 7% higher than the system with two ejectors.关键词
