摘　　要：介绍了一种太阳能辅助空气源热泵设备。该设备通过渗透型空气集热器预热蒸发器侧空气,不仅可以提高热泵的能效,也可以扩大热泵的适应地域的范围。本研究采用计算机软件模拟方法研究了典型气候区室外温度对空气源热泵制热性能的影响,并现场实际测试了太阳能集热系统对室外温度的提升能力和室外温度提升前后热泵的能效系数增量,模拟计算和实际测试结果互相印证。设备对进入蒸发器的空气进行预热,经计算和实际测试证实,设备能够有效提升空气源热泵的能效达23.4%以上。设备可在成熟的空气源热泵基础上直接进行简单改装,初投资低,操作简单;设备蒸发器侧空气温度每提高1℃,机组COP增量约为0.068,效益显著。设备在当前北方地区大力推行空气源热泵供热的背景下,具有显著的应用推广价值。A solar-assisted air source heat pump equipment is expounded. The device can not only improve the energy efficiency of the heat pump,but also can expand the geophysical adaptability of heat pump. The paper is based on the actual situation in China-solar heating area is rich in solar energy resources. So,increasing air temperature by solar energy,and then to increase heat pump efficiency is a viable approach to achieve energy conservation. This paper studied the effect of outdoor temperature on the air-source heat pump heating performance by means of computer simulation. We studied the ability of solar collector system to improve the outdoor temperature and the influence to the efficiency of air source heat pump by testing method. Simulation and actual test results prove the correctness of the research. The device preheats the evaporator side air through a permeable solar air collector. As testing results,the equipment can effectively improve the air source heat pump energy efficiency of more than 23. 4%,and the equipment's COP increases about 0. 068 as the evaporator side air temperature increases by 1℃,which will bring significant economic benefits. The main research results can not only provide a design guide for engineers,but also promote the heat pump technology.
