| 中文摘要: |
| 西安东郊幸福林带项目地源热泵工程开发利用研究工作,主要包括勘探孔钻探、岩土体热物性测试、现场热响应试验。在场地进行了勘探孔钻探,对地层岩性进行编录并取样。岩土热物性测试显示:中砂的导热系数最高为2.20 W/m·K,粉土的比热容最大为1.40 kJ/kg·K。进行了两种工况下的热响应试验,其中加热恒热流双U型(7 kW)试验工况下的效果较好,冬季单米换热量为37.29 W/m,夏季单米换热量为52.41 W/m。根据勘查和热响应试验结果,经过综合研究,认为研究区适宜进行浅层地热能开发,并对该区浅层地热能资源是否可以满足建筑换热需求做出了评价。最后提出该区浅层地热能开发的布孔方案。 |

| Describe the research on development and utilization of ground-source heat pump engineering in Xingfu Forest Belt in Xi’an City, including drilling of exploratory well, thermal properties test of rock-soil body, in-situ thermal conductivity test. During drilling exploratory well , take geological logging formation sampling. The result of thermal properties test of rock-soil body indicate that thermal conductivity of medium sand is highest and heat absorption capacity of silly soil is highest . Carry on in-situ thermal conductivity test in two operational mode. The result of test in constant heating(7 kW) operational mode is better than another. Performance of heat transfer per meter is 37.29 W/m in winter. Performance of heat transfer per meter is 52.41W/m in summer. According to result of exploration and in-situ thermal conductivity test, develop shallow geothermal energy in this site is suitable. And evaluate that if shallow geothermal energy capacity in this site could satisfy the requirement of building heating. Propose the plan of drilling well layout. |
