摘　　要：在武汉市地源热泵系统采暖季节测试的基础上,讨论了采暖工况下地源热泵机组及系统能效系数以及水系统输送系数,并与常规冷水机组+燃煤锅炉系统比较,分析了系统节能量、环境效益及增量投资回收期。得出结论:土壤源热泵水系统平均输送系数大于地下水源热泵系统;采暖工况地源热泵系统能效系数高于制冷工况,采暖季节比制冷季节节能率约高19.74%;单位建筑面积平均每年可减排二氧化碳18.35 kg、二氧化硫0.15 kg和粉尘0.074 3 kg;土壤源热泵系统的投资增量回收期比水源热泵系统高23%,费效比高32%。Based on the heating season testing of ground-source heat pump system in Wuhan, the article discussed the energy efficiency coefficient of heat pump host and system under the heating conditions and water system transfer coefficients. By comparison with conventional chillers ＆ coalfired boiler system, the system energy savings, environmental benefits and incremental payback period were analysized. There came to the conclusion that the average water system transmission coefficient of ground-source heat pump was greater than the ground-water source heat pump, the energy efficiency coefficient of ground-source heat pump system under heating conditions was higher than cooling conditions, the energy saving rate of the heating season was about 19.74% high- er than the cooling season, reducing 18.35 kg carbon dioxide emissions, 0.15 kg of sulfur dioxide and 0.074 3 kg of dust per unit construction area each year. The payback period of ground-source heat pump system was 23% longer to water-source heat pump, with the cost-effective ratio 32% higher.
