对太阳能热泵系统在居住空间供暖和生活热水供暖中的性能进行了对比研究。在威斯康星州的麦迪逊和新墨西哥州的阿尔伯克基两个不同的气候条件下，用TRNsys[1]对三种基本的组合配置以及传统的太阳能和常规热泵系统进行了模拟。这三种组合系统是串联系统，其中太阳能蓄热源作为热泵的源，并联系统中，环境空气作为热泵的源，以及双源系统中，根据哪个源产生的功输入最小，将蓄热源或环境作为源。确定了集热器面积、玻璃数目、主蓄热体积与集热器面积之比、热泵性能系数等参数对系统性能的影响，结果表明，并联组合系统可能是最实用的太阳能热泵系统。在采暖季节，给定集热器区域的热性能始终优于串联或双源系统。成本和需要夏季制冷的程度决定了传统热泵、传统热泵、传统太阳能和并行系统的相对优势。
A comparative study of the performance of combined solar heat pump systems for residential space and domestic hot water heating has been undertaken. Simulations have been made with TRNSYS[1] of three basic combined configurations, as well as conventional solar and conventional heat pump systems, in two different climates, Madison, Wisconsin, and Albuquerque, New Mexico.The three combined systems are the series system in which the solar storage is used as the source for the heat pump, the parallel system in which ambient air is used as the source for the heat pump, and the dual source system in which the storage or ambient is used as the source depending on which source yields the lowest work input. The influence of collector area, number of glazings, main storage volume to collector area ratio, and heat pump coefficient of performance were determined.The results indicate that the parallel combined system is probably the most practical solar-heat pump configuration. The thermal performance at a given collector area is consistently superior to both the series or the dual source systems over the heating season. Costs and the extent to which summer cooling is a requirement determine the relative merit of the conventional heat pump, conventional heat pump, conventional solar, and parallel systems.
