Joint Operation Test and Analysis of Solar Air Source Heat Pumps
[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℃,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℃.[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.
