COMPREHENSIVE BENEFIT ANALYSIS OF GROUND SOURCE HEAT PUMP SYSTEM
-
摘要: 引入净年值分析方法,在分析影响地源热泵系统效益评价因素的基础上,建立了综合效益评价模型。以天津某工程为例,对地源热泵系统与分散式制冷机房+市政热网系统进行综合比较,结果表明:地源热泵系统净年值增加额ΔNAV为162.8万元,该项目年运行费用减少51.3万元,年节约标准煤481.4 t,经济及环境效益显著。并对地源热泵系统的财务内部收益率进行了敏感性分析,为企业优化投资决策,规避风险提供参考。Abstract: Based on the method of Net Annual Value and the efficiency evaluation factors of ground source heat pump system ( GSHP) ，this paper proposed a comprehensive benefit evaluation model． Taking a project in Tianjin as an example，an integrated comparison of GSHP and distributed cooling machine + municipal heating network system showed that the former had remarkable economic and environmental benefits． The increase earnings in NVA of GSHP was 162. 8 million yuan，saving annual operating costs of 51. 3 million yuan and standard coal of 481. 4t． The study analysed the FIＲＲ of GSHP by using the sensitivity analysis method，providing a reference for optimizing the investment and evading risks．
