摘　　要：文章研究了严寒地区由太阳能-地源热泵与热网组成的互补供暖系统,在串联和并联两种运行方式下的性能情况。文章构建了两种运行方式下互补供暖系统的仿真模型,对该系统各部件进行了选型设计,对系统性能进行了仿真模拟并进行了经济性分析。结果表明:串联运行方式下互补供暖系统中地埋管换热器与土壤之间的最大换热效率比并联运行方式高19.8%,且串联运行方式下二者之间的换热总量要比并联运行方式高出9.44%;两种运行方式下埋管进出口水温均有下降;运行5 a后,并联运行方式下互补供暖系统的运行费用较串联运行方式下互补供暖系统略高,但从系统供暖能效及土壤温度的受扰动情况来看,并联式系统比串联式系统更具优势。The article studies the performance under tandem and parallel- the two operation modes of solar energy-ground source heat pump and heating network complementary system in cold regions. It constructs the simulation model of the complementary heating system in two operation ways, makes type selection design to all the components of the system, and simulates the system performance and economy analysis. The results show that the maximum heat transfer efficiency of the tandem system between the ground heat exchanger and the soil is 19.8% higher than that of the parallel system, the amount of heat transfer of the tandem system between the ground heat exchanger and the soil is 9.44% higher than that of a parallel system; The import and export of buried pipe water temperature in two operation ways are both decreased; After five years of operation, the operating costs of parallel heating system are slightly higher than that of tandem heating system,however, from the system heating efficiency and the disturbance situation of soil temperature, the parallel heating system has more advantages than the tandem heating system.
