摘　　要：基于某工程实例,采用BIN法对其全年能耗进行了分析计算,以此为基础对比了地下水源热泵系统和常规水冷空调系统的费用年值,并分析了地下水源热泵系统的追加投资回收期。计算结果显示虽然地下水源热泵系统的初投资较高,但其费用年值仅为常规水冷空调系统的91.6%,且3.8年左右就可把追加投资完全收回,所以使用地下水源热泵系统不仅可以提高一次能源利用率,而且可使用户获得经济效益。Based on an example project,BIN method is used to analyze its annual energy consumption.And a comparison is made between groundwater heat pump（GWHP） system and conventional water-cooled air conditioning system with respect to the annual cost on the basis of energy consumption calculated before.Also,an analysis is made to evaluate the additional cost payback period of GWHP system.The results show that although the initial cost for GSHP system is higher,its annual cost is 8.4% lower than that of water-cooled air conditioning system;moreover,its back period for additional initial cost is about 3.8 years.So GWHP system can not only improve the primary energy efficiency,but also enable the users to obtain economic benefits.
