能源桩技术的研究与发展

Research and development on energy pile technology

全球环境污染、能源供应不足等问题愈发严重,我国对能源可持续发展的要求也越来越高。通过对能源桩发展历程与背景的梳理,采用聚类分析等方法发现能源桩在节能减排方面的优势格外突出。能源桩早在1 855年便已出现,日本、瑞士等国的能源桩技术已较为成熟,目前在我国应用较少。能源桩技术具有以往能源技术不可比拟的突出优势:提高能源利用效率和带来更好的经济效益,并且螺旋型能源桩优于3U型能源桩。能源桩同样存在圆柱型螺旋能源桩的热干扰现象、群桩效应问题、相应系数修正以及对周边环境、设施可能产生不利影响等缺点,但是能源桩发展潜力仍然巨大,通过在能源桩混凝土中加入不同增强材料可以获得不同的强化换热效果,这将为建筑物节能减排提供新的思路。

Global environmental pollution,energy supply insufficient and other problems are becoming more serious and China's requirements of the sustainable energy development are also getting higher.With the combing on the development history and background of the energy pile,the cluster analysis and other methods applied showed that in the energy conservation and emission reduction,the energy pile would have the outstanding advantages.The energy pile was appeared as early as 1855,the energy pile technology in Japan,Switzerland and other countries are becoming relatively mature.At present,the application of the energy pile technology is less in China.The energy pile technology would have the incomparable outstanding advantages than the previous energy technology,could improve the energy utilization efficiency and could bring about the better economic benefits.The spiral type energy pile is better than the three-U type energy pile.In the energy pile,the cylindrical spiral energy pile also would have the thermal interference phenomenon,group pile effect problem and corresponding coefficient correction as well as would cause the adverse effect and other disadvantages to the surrounding environment and facilities.But the development potential of the energy pile would also be great.With different strength improved material added in the concrete of the energy pile,the different enhanced heat exchange effects would be obtained and thus a new ideal would be provided to the energy conservation and emission reduction of the buildings.
