摘　　要：介绍一种由太阳能集热子系统(SES)、喷射子系统(ES)、机械压缩子系统(CRS)组成的热电互补高效空调系统(HEACS)。充分利用两种能源及各制冷方法的优点,通过能源特性匹配和制冷方法互补的途径,改善压缩式子系统的工作条件,提高复合制冷系统性能的同时节约高品位电能。通过实验分析太阳能集热子系统及喷射子系统的工作特性,并选取工作工况,为其应用于复合式系统提供研究基础及依据,进而测试热电互补高效空调系统性能。实验结果显示:与相同工作条件下的单压缩制冷循环相比,喷射/压缩复合式制冷循环运行工况的性能系数提升约30%,节电优势显著。A high efficiency air conditioning system driven by solar and electric energy complementary(HEACS)is proposed in this paper.The system consisting of three subsystems(solar energy subsystem(SES),ejection subsystem(ES),compression refrigeration system(CRS))makes full use of the advantages of the two grades of energy sources and refrigeration methods in order to improve the system performance and save high grade energy consumption by improving the working conditions of CRS.The subsystem working conditions are optimized based on the experimental analysis of the working performance of the SES and the ES.Then,the prototype of HEACS is developed to measure the operational performance.The experimental results show that:compared with the conventional compression refrigeration cycle under the same working conditions,the improvement of performance coefficient of the HEACS is about 30%.The advantage of power saving is significant for the future application.
