Experimental case analysis of solar air collector and heating system in rural areas of North China

In this paper, we take solar air collector and heating system in Shijiazhuang city as a case to illustrate the system design and operation principle and analyze the operation data of the system. According to the results, the room temperature can be maintained at 18-22℃ during the daytime and 15-18℃ at night with electric auxiliary heating. It provides a reference for the promotion of solar air collection and heating in rural areas of north China.
