摘　　要：针对江苏省江阴市某休闲会所商用建筑的土壤源热泵系统,采用TRNSYS软件模拟并分析了冬夏季供暖空调期土壤源热泵系统COP的变化。结果表明,在地埋管深度为100 m情况下,热泵系统的供热季节性能参数为3.31,供冷季节性能参数为3.37。对该地区的土壤源热泵系统采用层次分析法构建了评价体系,进行适宜性评价指标计算,并对土壤源热泵系统和常规冷热源系统的经济性和环境性进行了对比分析。与常规冷热源系统相比,土壤源热泵系统年运行费用是常规冷热源系统的75.6%,一次能源利用率高出13%,节约标煤量达1.71 t,温室气体减排量为4.47 t,全年能效比为2.74。土壤源热泵系统具有明显的节能、经济、环保优势,适宜性较好。According to a ground coupled heat pump(GCHP)system for a commercial building in Jiangyin city,Jiangsu province,a model was built based on TRNSYS software to simulate and analysis its coefficient of performance(COP)under different working conditions.The results showed that the heating season performance factor(HSPF)of heat pump system was3.31in summer and the seasonal energy-efficiency ratio(SEER)was3.37in winter when the pipe buried depth was100meters.Analytic hierarchy process(AHP)was used to evaluation the suitability of GCHP system,and compared with the conventional system in terms of economic and environmental performance.It was found that the operating cost of GCHP system was75.6%of the conventional system,the primary energy ratio was13%higher,save coal amount was1.71tons,greenhouse gas reductions was4.47tons,and the all-yearly energy-efficiency ratio was2.74.The GCHP system presents high suitability regarding its advantages in energy-saving,economic,and environment protection.
