以U型管式太阳集热器作为热泵系统的蒸发器,利用太阳能工程及传热学等热力学相关知识,对该直膨式太阳能热泵系统进行能效分析.论证结果表明:太阳集热器的综合效率达到90%以上,系统能效COP约3.53,同时以上海地区单户采暖为例,描述直膨式太阳能热泵采暖蓄能供冷系统的设计过程,该研究能够为太阳能热泵采暖及蓄能供冷的优化设计提供借鉴.%In this paper,the U type tube solar collector was used as the evaporator of heat pump system,with the usage of solar energy engi-neering and heat transfer thermodynamics knowledge,energy efficiency analysis of the direct expansion solar heat pump system are carried out. The results show that the comprehensive efficiency of the solar collector reaches to more than 90%,and the energy efficiency of the system is about 3.53 COP. The design process of a direct expansion solar energy heat pump system for heating and cooling is described by individual household heating in Shanghai. The research can provide reference for the optimization design of solar heat pump heating and energy storage and cooling.
