【摘要】 目前，环境污染、能源的匮乏已经是世界各国急待解决的重大问题。北京作为中国的首都，曾是世界上污染最严重的城市之一。随着北京2008年奥运会的申办成功，解决北京的环境问题显得更加迫切。而地热作为一种清洁可持续利用的能源，地热能供暖系统的研究与推广必将为解决北京的环境问题做出巨大的贡献。本论文则针对北京工业大学地热供暖示范工程实例，对地热梯级利用供暖系统的设计、技术性能、经济性能进行分析与研究。 本论文首先介绍了北京工业大学地热供暖示范工程中经管楼地热利用供暖中试系统和综合楼与图书馆地热利用供暖系统的方案设计，为低温地热水的合理利用提供了两种工程模式。并且分析了所使用的主要采暖设备热泵、风机盘管的性能分析。在示范工程系统中进行了大量的试验，对地热梯级利用供热系统的技术性能和经济性能进行综合分析。通过对系统进行改进，地热梯级利用供暖系统的经济性得到进一步提高。最后根据设计经验、设备性能以及相关的影响因素，总结出地热梯级利用供暖系统级数的确定原则。本论文的结论对低温地热水的合理利用以及地热梯级利用供暖系统的设计、推广具有广泛的指导意义。更多还原

【Abstract】 At present, the environmental pollution and the lack of unsustainable energy have become necessary problems in every country all over the world. Beijing, the capital of China, was one of the most polluted cities. With applying for the Olympic Games in 2008 successfully, the solution of the environmental pollution in Beijing become more urgent. Since Geotherm is a kind of clean and sustainable energy, the Gradient Utilization System of Geotherm will play an important role in the related field. In the thesis, the schemes of system, technical performance and economic performance were researched and analyzed through the Demonstration Project of the Geothermal Space Heating of Beijing University of Technology.To start with, two kinds of the engineering models were introduced in the thesis through the design in the middle-size Gradient Utilization of Geothermal Energy for Space Heating System (GUGESHS) in the building of the School of Economics and Management, the Geo-heat system for space heating in the Yifu Library and the Multi-function Sci-Tech Block. And the performance of the main heating equipment using in the two systems including heat pump and fan coil were analyzed. Moreover, the technical and economic performances of GUGESHS are analyzed comprehensively in terms of plenty of measurement in them. And the economic performance has been improved by amending these systems. At last, according to the designing, operating practice, heating equipment performance and related factors, the principle of confirming the number of stages in the GUGESHS were suggested in this thesis. Above all, the conclusion in the thesis plays an important role in the reasonable utilization of the low temperature geothermal water and the design of the GUGESHS.更多还原
