| 摘 要： | 为研究地埋管换热器在不同岩性地层的换热情况,在鲁西黄河冲洪积平原、山前冲洪积平原和低山丘陵区进行了以粉土、粉质粘土、细砂,粘土、粉质粘土、中粗砂,灰岩和花岗岩为研究对象的热响应试验,初步试验结果表明:每延米换热量(W/m)和平均热导率(W/m·k)花岗岩灰岩粉质粘土、中粗砂粉土、粉细砂。在岩溶地下水富水性强,径流速度快的地段灰岩平均热导率花岗岩。此项研究结果可为不同岩性地层浅层地温能开发利用工程地埋管换热器类型的选择,浅层地温能评价和开发利用提供基础数据。

| Abstract: | in order to study heat transfer of buried pipe in different strata of the heat exchanger, regarding silt, silty clay and fine sand, clay, silty clay, sand, limestone and granite as the research object, thermal response test has been carried out in the Yellow River alluvial plain, the piedmont alluvial plain and hilly area in Luxi region. As showed by the preliminary test results, as to per meter heat transfer (W/m) and the average thermal conductivity (W/m·k), the largest is granite hole, followed by limestone hole and silty clay, sand hole, and the minimum is silt and fine sand hole. In the karst groundwater enrichment strong and runoff area, the average thermal conductivity of limestone hole is larger than it in the granite hole. This study can provide basic data for buried tube heat exchanger type selection of ground shallow geothermal energy development and utilization project in different strata, shallow geothermal energy evaluation and development and utilization. |
