不同地质条件下地源热泵取热方式技术经济性分析
Technical and economical analysis of heat obtaining method of ground-source heat pump under different geological conditions
摘要：
以保定市某地源热泵项目为研究对象，详细分析了钻孔设置竖直埋管换热器方式和地下水抽灌井方式的系统设计方案、资源条件、初投资及运行成本。结果表明地下水抽灌井方式取热方案的初投资是钻孔设置竖直埋管换热器方式的1/2以下，但其总运行费用要远高于钻孔设置竖直埋管换热器方式。

Abstract：
Taking a ground-source heat pump system in Baoding City as an object, analyses in detail the design scheme, resource conditions, primary investment and operation cost of vertical pipe heat exchanger buried in bore and underground water pumping/recharging wells. The results show that the primary investment of the underground water pumping/recharging well is lower 1/2 than that of the vertical pipe buried in bore, but its total operation cost is far higher than that of the vertical pipe buried in bore.
Keywords:ground-source heat pump, heat obtaining method, water resource cost, operation cost, technical economical comparison
