地埋管地源热泵技术在贵州岩溶地区的应用研究

Application Research on Buried Ground-source Heat Pump Technology in Karst Area of Guizhou

摘要:

地埋管热泵技术是采集地表以下200 m深度内的浅层地热能进行供热制冷的新型能源利用技术，而该技术在贵州碳酸盐岩分布区的应用和推广之所以受到制约，其主要原因是岩溶地层中建造垂直换热孔的难度大、成本较高。通过贵州省有色科技大楼附楼采用垂直地埋管式与基础桩螺旋盘管式有效组合的换热系统，在岩溶一般至中等发育的碳酸盐岩地层中开发利用浅层地热能的成功经验的介绍，为地埋管热泵技术在贵州岩溶地区的应用和推广提供参考。

Abstract:

Buried heat pump technology is a new energy utilization technology for heating and cooling with shallow geothermal energy collected below the surface within 200m in depth, but which is restricted in the application in carbonate rock distribution area of Guizhou mainly because of the difficulties in vertical heat exchange hole building in Karst formaton and the high cost. The paper introduces the successful experience of utilization of shallow geothermal energy by a combined heat exchange system of vertical buried type and foundation pile spiral coil type in carbonate formation with Karst general to medium development, which can be reference for the application and promotion of buried heat pump technology in Karst areas of Guizhou.
