Heating Performance of a Novel Centralized Solar Heating System Coupled with a Water-Water Heat Pump in Lhasa, China
In this paper, a novel centralized solar heating system coupled with a water-water heat pump (Coupled-CSHS) is proposed to improve the heat collection efficiency of solar collector field (SCF). A residential building in Lhasa is selected as the research object, and a system model is established through TRNSYS for analysis. The results show that when the SCF area is 80 m2, the Coupled-CSHS can improve the heat collection efficiency by more than 10% and the solar fraction by 13.9%. However, as the area of SCF increases, the advantages of Coupled-CSHS in heat collection efficiency and solar fraction are no longer significant. Therefore, when designing the solar fraction of the Coupled-CSHS, the solar fraction should be less than 80%. At this time, the heat collection efficiency can be increased by at least 5%, and the SCF area can be reduced by more than 6.3%.
