摘　　要：为提高太阳能耦合污水源热泵热水系统的太阳能保证率、降低运行能耗,文章提出了SFEC评价指标,利用TRNSYS软件建立了系统模型,并采用田口方法对影响该系统SFEC的4个因素进行试验设计;然后,对试验方案结果进行主效应及相关统计分析。分析结果表明,因素的影响排序依次为太阳能集热面积/蓄热水箱体积(A/V)>热泵机组容量>恒温水箱体积>太阳能集热器安装倾角。根据最优参数组合对系统进行优化,优化后系统的年太阳能保证率平均值提高了3.6%,年运行能耗降低了4.52%。文章研究成果可为太阳能与热泵耦合以及能源互补热水系统的设计与优化提供参考。In order to improve the solar fraction of the system and reduce the operating energy consumption,this paper put forward the SFEC evaluation target and used TRNSYS to establish the system model.The taguchi test was designed to study the four key factors affecting the SFEC of the Solar-assist Sewage Source Heat Pump Coupling Hot Water System.Then,the main effect and related statistical analysis were carried out on the results of the experimental plan.The results show that the order of influence of the factors is solar collector area/heat storage tank volume(A/V)>heat pump unit capacity>constant temperature tank volume>solar collector inclination.The system was optimized for operation according to the optimal parameter combination.The optimized annual solar fraction is increased by 3.6%on average,and the annual operating energy consumption is reduced by 4.52%.The paper provides references for the design and optimization of the coupling of solar energy and heat pump and the design and optimization of energy complementary hot water system.
