摘　　要：煤矿冻结法施工后遗留大量废弃的冻结管,这些冻结管管径粗,埋深大。用废弃冻结管作为地埋管换热器,不但换热量远超过传统地源热泵的地埋管换热器,而且废物利用,大大节约了工程投资。文章以实际工程为例,介绍了利用冻结管作为地源热泵换热器的热泵系统工程设计方法。After the construction with the mine ground freezing method completed,there would be a plenty of the abandoned freezing pipes left.Those freezing pipes abandoned with a large diameter and a high depth could be applied as the underground pipe heat exchanger.The heat exchange quantity of the abandoned freezing pipe would be higher than the underground pipe heat exchanger of the traditional geothermal heat pump,the abandoned pipe could be utilized and the project investment could be highly reduced.Based on the actual project as the case,the paper introduced the design method of the geothermal heat pump system with the utilization of the abandoned freezing pipe as the geothermal heat exchanger.
