摘　　要：针对空气源热泵系统在北方冬季由于蒸发温度低而导致的制热效率低下的问题,本文采用了低温太阳能热水辅助空气源热泵采暖的解决方案,搭建了太阳能辅助空气源热泵系统试验台。本文对空气源热泵系统和太阳能辅助空气源热泵系统这两种运行模式下的制冷剂进出口温度、室内温度等参数进行了测试、对比,计算并且分析了系统的制热量和制热系数,得出太阳能热水辅助系统较空气源热泵系统,能够使室内温度提升4℃,COP提升1.3,热泵系统能够稳定、可靠、高效运行。与传统的空气源热泵系统相比,太阳能热水辅助空气源热泵系统具有较大的环保潜力、节能潜力。The standard- alone air- source heat pump （ASHP） system usually has a very poor heating effi- ciency in the cold climate due to its inherent technical constrain of low evaporation temperature . This paper thus adopted a solution of a solar assisted air source heat pump （SASHP） system for heating and set up a SASHP system＇ s testing board. Parameters such as the temperature of import and export of refrigerant and in- door air temperature of the two operating modes of ASHP system and SASHP system were tested and compared , then the heating capacity and the coefficient of performance （COP） were calculated and analyzed . Com- pared to the ASHP system, the proposed SASHP system could increase the indoor temperature by 4℃; the COP of 1.3 times and the system could operate stably, reliably and efficiently. Compared with the convention- al ASHP system, SASHP system has great potential to environmental protection and energy saving.
