串联式复合地源热泵系统技术经济性分析
Technic-economic analysis of series connected hybrid ground source heat pump systems
摘要：
以湖南省株洲市一商业建筑为研究对象，利用EnergyPlus能耗模拟软件模拟了其全年负荷。在此基础上对冷却塔与地埋管换热器分别承担不同比例冷负荷时系统的初投资、运行费用、多年运行总费用和全寿命周期成本等进行了计算分析。结果表明，复合式地源热泵系统如果配置不当，不但不会提高系统的经济性，反而会适得其反。

Abstract：
Taking a commercial building in Zhuzhou city, Hunan Province as the research object, simulates its annual load with EnergyPlus. On this basis, calculates the initial investment, operating cost, total cost and the life cycle cost of the system in which the cooling tower and the ground exchanger shares different proportion of the cooling load. The results show that the improper configuration of a hybrid ground source heat pump system will result in diseconomy.
