摘　　要：【目的】为了研究太阳能空气源热泵相结合的采暖系统实际运行状况,对实际运行的太阳能空气源热泵联合运行系统进行了测试。【方法】对呼和浩特市使用太阳能空气源热泵系统的2座加油站进行现场测试数据采集和分析,测试数据包括在不同的环境下的耗电量、供热量、温度等。【结果】根据实际的测量结果可知,当环境温度相差不大时,不同年份对应月份的耗电量也相差不大;当环境温度为-20℃时,系统性能系数COP依然能达到2.4以上。随着环境温度的升高,性能系数COP逐渐增大。当环境温度为5℃时,系统性能系数COP达4.0以上。【结论】太阳能辅助加热有助于提高热泵系统整体性能,是一种适合低温环境下运行的空气源热泵采暖系统。[Purposes]In order to study the actual operation of the heating system combined with solar air source heat pump,the actual operation of the solar air source heat pump combined operation system was tested.[Methods]Field test data collection and analysis were carried out on two gas stations in Hohhot using solar air source heat pump systems,including data on power consumption,heat supply,tempera⁃ture and other data at different ambient temperatures.[Findings]According to the actual measurement results,when the ambient temperature is not much different,the power consumption of the corresponding months in different years is not much different,and the system COP can still reach more than 2.4 when the ambient temperature is-20°C,and the coefficient of performance COP gradually increases with the increase of ambient temperature,and the system COP reaches more than 4.0 when the ambient tempera⁃ture is 5°C.[Conclusions]Solar-assisted heating helps to improve the overall performance of the heat pump system,and is an air source heat pump heating system suitable for operation in low temperature en⁃vironments.
