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。
A mathematical model for solar air-assisted compression air-conditioning refrigeration system was established and its application in Beijing area was simulated. Based on the simulation results, the system performance and operating characteristics of the solar-assisted compression air-conditioning refrigeration system are analyzed, and the evaluation index of the comprehensive mechanical performance coefficient is proposed. Compared with the traditional compression refrigeration system using compressors, solar-assisted compression air conditioning refrigeration system can save about 10% of energy. The performance and operation characteristics of the solar assisted injection air-assisted compression air conditioning and refrigeration system are greatly influenced by the parameters of solar radiation intensity, outdoor air temperature, storage tank volume, etc., and need to be further optimized according to the use environment.
