【Abstract】 In response to the demand of clean heating for rural households in areas with abundant solar energy, this paper adopts the technical form of PV/T heat pump heating, and uses a single-family building in a rural area of Lanzhou with a heating area of 64 m~2 as the object to build a Trnsys simulation model. With solar energy guarantee rate and system efficiency as evaluation indicators, the paper first determines the main influencing factors through a two-level orthogonal experiment, which shows that the main influencing factors are PV/T area, rated heating power of heat pump, tank1 capacity, and the interaction between PV/T area and tank1 capacity. Based on this, the paper further conducts a four-level orthogonal experiment, and analyzes the single factor and interaction effects of the experiment results to obtain an optimal solution. The optimal configuration parameters of the system are 20 m~2 PV/T module area, 5 000 W rated heating power of the heat pump, and 0.9 m~3 Tank1 capacity. The solar energy guarantee rate can reach 82.35%, and the system efficiency is 53.49%.更多还原
