The Application of Ground Source Heat Pump System and Its Economic Analysis

介绍了土壤源热泵的工作原理,根据工程周围的环境,地质条件,对抚顺市某垂直埋管式地源热泵系统工程的实例进行了分析。并将垂直埋管式地源热泵空调系统与燃油锅炉+冷水机组空调系统进行了经济分析比较。结果表明,土壤源热泵系统初投资高出燃油锅炉+冷水机组空调系统约4倍,而土壤源热泵系统要比燃油锅炉+冷水机组空调系统节省约63%的全年运行费用,其中夏季节省约21.5%的运行费用,冬季节省运行费用较大约为67.9%。土壤源热泵系统初投资回收期短,经济可行性好。

This paper briefly describes the working principle of ground source heat pump and analyzes a vertical loop of pipe ground source heat pump system engineering example.The surrounding environment based on the engineering and geological conditions,through the demonstration program,and compare with oil-fired boiler ＋ water chillers air conditioning system’s economic situation.The results showed that ground-source heat pump system,the initial investment of ground source heat pump system is about three times higher than oil-fired boiler ＋ chiller water conditioning system,while the operating costs of the ground-source heat pump system is 40% less than that of the oil-fired boiler＋chiller air conditioning system throughout one year.There is 12% less in summer and 60% less in winter.The initial investment payback period of ground source heat pump system is short,and in comparison with oil-fired boiler＋chiller water conditioning system,the ground source heat pump system has a good economic viability.
