摘　　要：针对严寒地区的气候条件,选取哈尔滨地区某居民住宅小区作为研究对象,利用TRNSYS软件对太阳能-土壤源热泵联合供暖系统(SGCHP)进行计算分析。结果表明:太阳能-土壤源热泵联合供暖系统中太阳能集热器对热泵机组的进水温度和COP以及节电量等方面有改善作用;对太阳能-土壤源热泵联合供暖系统中太阳能集热器面积与地埋管管长的最佳配比的优化结果表明,1 m^2太阳能集热器可保证17～27 m长的地埋管取热平衡。并继续模拟了沈阳地区,并以哈尔滨地区为基准,给出严寒地区该参数的推荐值。According to the climatic conditions in cold region, a residential area in Harbin was selected as research object, and the solar-ground source combined heat pump heating system(SGCHP) was analyzed by TRNSYS software. The results show that the solar collector in the solar-ground source combined heat pump heating system can improve the inlet water temperature and COP of the heat pump unit and the power saving. The optimal results of the optimal ratio of solar collector area to buried tube length in the solar-ground source combined heat pump heating system show that 1 m^2 solar collector can guarantee 17-27 m long underground pipe heat balance. and continue to simulate the, Taking Harbin as a benchmark, the system in Shenyang was also simulated and the recommended values of the parameter in the cold area is given.
