摘要
针对太阳能喷射辅助压缩式空调制冷系统建立了数学模型,并对其在北京地区的应用工况进行了模拟计算。基于模拟结果,对太阳能喷射辅助压缩式空调制冷系统进行了系统性能及其运行特性分析,并提出综合机械性能系数的评价指标。与传统采用压缩机的压缩式制冷系统相比,太阳能喷射辅助压缩式空调制冷系统可节省电能约10%。太阳能喷射辅助压缩式空调制冷系统的性能和运行特性受太阳能辐射强度、室外空气温度、蓄热水箱体积等参数综合的影响较大,需要根据使用环境的不同进一步优化。
Mathematical model of an ejector based solar energy assisted compression refrigeration system for air conditioning was developed and simulation work was done when the system was used in Beijing. Based on the simulation results, the system＇s operating characteristics and performance was analyzed and a performance evaluation index named comprehensive coefficient of mechanical performance was presented. Compared with traditional refrigeration system using compressor, ejector based solar energy assisted compression refrigeration system could reduce the electricity consumption about 10%. Ejector based solar energy assisted compression refrigeration system was influenced by solar radiation intensity, outdoor air temperature and the volume of the hot water storage tank, and should be optimized according the application conditions.
