【摘要】：地埋管地源热泵技术以其自身的节能和环保性在我国能源短缺和环境恶化的大背景下，引起人们越来越多的关注和重视。河北省是我国最早研究和应用地埋管地源热泵技术的地区之一，由于其气候及水文地质等条件比较适合地埋管地源热泵应用技术的发展，并且政府也出台了相关的扶持政策，近几年该技术在河北省的发展非常迅速，并且在一些地区已经建成了典型的示范工程。本文分析国内外地埋管地源热泵应用技术的发展现状，结合河北省内地埋管地源热泵技术的推广发展状况，发现在对地埋管地源热泵技术的大力推广和应用过程中，存在很多问题。虽然地埋管地源热泵应用技术的相关理论研究方面已趋于成熟，但是在实际应用中的经济性分析还甚少，由于实际案例建筑属性、地质情况、能源价格、政策引导等不同因素的影响，各地的地埋管地源热泵系统的经济特性不尽相同，导致开发商和业主对采用地埋管地源热泵技术持观望和谨慎的态度，这也是地埋管地源热泵应用技术在现实中推广的最大障碍。针对上述情况，本文在河北中南部地区选取了5个不同地质构造的地埋管地源热泵系统项目案例，介绍了系统节能性和经济性分析理论和方法，通过分析各个案例的初投资、年运营费用等经济性构成，对地埋管地源热泵系统和空气源热泵系统及传统中央空调供热系统（冷水机组+集中供热）的性能系数等节能性指标，投资增量的回收期（静态和动态）、动态费用年值等经济性指标进行了分析计算。结果表明地埋管地源热泵系统相对其他两种方案的节能和经济优势巨大。同时计算了系统运行年限内地埋管地源热泵系统相对于空气源热泵和传统中央空调供热系统少向环境中排放的污染物总量和总节省的运营总费用。最后总结了全文的主要内容，，提出了案例节能和经济性分析计算的结论。并提出了有待进一步研究的方向及本文的不足之处。希望本文可以对河北地区地埋管地源热泵应用技术的推广有一定的促进意义，为实际工程应用提供一定的经济性参考。
[Abstract]:GSHP Technology with its energy saving and environmental protection in the background of China's energy shortage and environmental deterioration, attracted more and more attention. Hebei province is one of the earliest GSHP Technology Research and application of underground pipe of area of our country, due to the development of the climate and hydrogeological condition suitable for GSHP application technology, and the government also introduced the relevant supporting policies, in recent years the technology in Hebei province is developing very rapidly, and in some areas has built a typical demonstration project.
This paper analyzes the development situation of GSHP application technology at home and abroad to promote the development of the embedded, combining Hebei province mainland buried groundsource heat pump technology, found in the promotion and application of GSHP Technology, there are a lot of problems. Although the relevant theoretical research of ground source heat pump application technology of buried pipe has become mature however, the economic analysis in practical application is still very little, because of the actual case of building property, geological conditions, energy prices, effects of different factors such as policy guidance, economic characteristics of the GSHP system is not the same as the tube around the ground, leading to the developers and owners of the GSHP Technology and cautious wait-and-see this is the attitude, the biggest obstacle buried pipe application technology promotion of ground source heat pump in reality.
In view of the above situation, this article in the south central area of Hebei selected 5 different underground geological structure of GSHP systems project cases, introduces the system of energy conservation and economic analysis theory and method, through the analysis of each case of the initial investment, annual operating expenses such as economic structure, the GSHP system and air source the heat pump system and the traditional central air conditioning heating system (chiller plus heating) performance coefficient of energy saving index, payback period increment (static and dynamic), annual cost analyses of other economic indicators calculation. The results show that the GSHP system relative to the other two schemes of buried tube energy saving and economic advantages at the same time. The system operates huge mainland buried groundsource heat pump system relative to the traditional central air conditioning and air source heat pump heating system to calculate the emission of pollutants in the environment Total cost of total and total savings.
Finally, a summary of the whole thesis, put forward the case of energy conservation and economy analysis. The conclusion and put forward the shortcomings of the direction of further research and promotion of this paper. I hope this can be for Hebei area GSHP application technology has certain significance to promote economy, provide reference for practical engineering application.
