Abstract

The rural houses are extensive in north China, whose heating demand is needed to be satisfied, and how to reduce the environmental pollution caused by heating facilities needs to be solved urgently. The abundant solar energy resources and solar photovoltaic-heating collector could provide ideas for this problem in northwest China. In this paper, a new household heating system of solar photovoltaic-heating collector assisted by air source heat pump is introduced firstly, and then, as a practical example, this household heating system is used in a farmhouse located in Lanzhou area and tested between February 1, 2018, and March 31, 2018. The results show that the heating system is feasible and the solar photovoltaic-heating collector mentioned in this paper can convert solar energy more efficiently. During the test period, the outdoor daily minimum temperature is between −14.5 and 10 °C, the indoor daily minimum temperature is between 14.3 and 16.1 °C, the conversion efficiency of solar photovoltaic-heating collector is between 0.4 and 0.7, and the operating cost of the heating system is about ¥552 per month according to the peak–valley electricity price implemented in this area. The household heating system of solar photovoltaic-heating collector assisted by air source heat pump in this paper could be a reference model to the rural clean heating project carried out in Chain.
