摘　　要：为了充分利用地源热泵的节能特性和辅助热源较低的初投资,针对新疆某市的气象条件和价格体系,通过实例模拟研究了地源热泵+燃气锅炉供热方式的节能特性和经济性。结果表明,对于地源热泵+燃气锅炉供热方式,设计负荷按60%+40%分配时,不会显著增加燃料耗量,但可以获得最佳的经济效果。此时,燃气锅炉的供热量仅占总供热量的8.3%,总标煤耗量仅比热泵承担100%设计负荷方案增加5.22%,而却可以获得最小的费用现值(249.3元/m2)和最大的增量净现值(47.8元/m2)。Ground source heat pumps（GSHPs） have advantages such as energy-saving and lower initial cost of auxiliary heat source.In this study, the characteristics of energy saving and economy of a GSHP with a gas boiler were investigated by numerical simulation and case study according to the weather data and fuel prices at a city in Xinjiang.The results show that if the design heating load of the GSHP and the gas boiler was 60% and 40%, respectively, the source energy consumption did not increase significantly, however, the best economy was achieved.In the case studied, the heat output of the gas boiler was only 8.3% of the total, and the total coal equivalent increased by only 5.22% compared with that in the case of 100% design heating load supplied by the GSHP, while the smallest present value of cost （249.3 Yuan/m2） and the largest incremental net present value （47.8 Yuan/m2） were acquired.
