摘　　要：为解决传统太阳能或地源热泵生活热水系统独立运行时存在的问题,该文将两者进行组合匹配得到复合式系统,结合逐月负荷变化来确定系统各设备选型范围,从中选取正交试验设计所需的各因素水平值;同时以长沙地区某高校学生宿舍的复合式热水系统为研究对象,通过动态模拟软件对不同组合下系统性能进行考察,并对试验结果统计分析,得出复合式热水系统中主要的设备及控制参数的最优匹配方案。本文的结论可为实际工程设计提供设备选型及控制设定的参考,有助于提高热水系统的经济效益。The hubrid system of conventional solar domestic hot water system and ground source heat pump domestic hot water system was established through the coupling of these two kinds of systems mentioned above. In this paper, research was concentrated on the hybrid system of a certain university dormitory located in Changsha, China. Based on monthly changes in the load of hot water usage, the selection ranges of equipment parameters of the hybrid system were attained, which was then used to determine the levels of each factor in the following orthogonalization analysis. Then the optimal matching of major equipment and control parameters in the hybrid system was obtained by dynamic simulation and statistical analysis, where optimal economic efficiency could be achieved. The conclusion was capable to be utilized as a reference for actual project in equipment parameters and control settings of the hybrid system.
