摘　　要：为提高太阳能水源热泵耦合系统性能,该文从设计及运行两方面对其进行优化研究。在建立太阳能水源热泵耦合系统应用模型的基础上,用瞬时系统模拟程序(Transient system simulation program,TRNSYS)软件搭建系统计算模型,以系统的设计参数如:太阳能集热器面积、储热水箱体积及集热器倾角等为变量,利用GENOPT软件对系统进行优化。并以系统运行控制参数如:集热器供回水温差和供暖末端供回水温差为变量分析系统性能参数(Coefficient of performance,COP),分析系统节能潜力。该文以北京某别墅为研究对象进行优化,结果表明系统COP升高、性能得到改善。研究结果为太阳能热泵系统优化提供了一定的理论依据。This paper optimizes a solar-assisted heat pump system on design and operation in order to improve its performance. We build a system model using transient system simulation program( TRNSYS),taking solar collector area,storage tank capacity and collector tilt as variables,and then optimize the design using GENOPT software. Meanwhile,we analyze the coefficient of performance( COP) and energy-saving potential of the system by taking temperature difference between supply and return water of heat collectors and that of heating terminal equipments as variables. The object of this study is a villa in Beijing. The study results show that the COP is increased and the performance is improved,which provide theoretical foundation for optimization on the solar-assisted heat pump system.
