一种地源热泵专用灌浆回填材料
摘要：
本发明涉及地源热泵系统技术领域，具体地说是一种地源热泵专用灌浆回填材料。灌浆回填材料的选择对于保证地埋管换热器的性能有重要的意义。研究开发高热导率新型回填材料，对推广地源热泵技术、发展低碳经济具有重大的社会经济效益。本发明提供了一种高热导性的回填材料，其配方是粉料与骨料的质量百分比为1∶2；其中粉料中含有金属及其化合物组份占粉料总质量的10％～20％，耐热水泥占粉料总质量的30％-35％，膨润土占粉料总质量的10％-15％，其余为粘土；骨料中有含有金属及其化合物组份占骨料总质量的15％～30％，其余为石英砂、三氧化二铝其中的一种或二种的混合物；减水剂占所有干料质量的0.3％。
摘要（英）：

The invention relates to the technical field of ground source heat pump system and specifically provides a grouting backfill material special for a ground source heat pump. Choice of the grouting backfill material has important meaning for guaranteeing performances of a ground heat exchanger. The research on development of a high thermal conductivity novel backfill material has significant socialand economic benefits for popularizing ground source heat pump technology and promoting low carbon economy. The invention provides a high thermal conductivity backfill material, comprising powder andaggregate in a mass percent of 1:2, wherein the powder contains metal and compound thereof accounting for 10-20wt% of the powder, heatproof cement accounting for 30-35wt% of the powder, bentonite accounting for 10-15wt% of the powder and the balance of clay, and the aggregate contains metal and compound thereof accounting for 15-30wt% of the aggregate and a mixture of one or two selected from quartz sand and alumina; and a water reducer accounts for 0.3wt% of the drier.
