摘　　要：为探讨银川地区地埋管地源热泵开发利用潜力,对研究区内地层特征及地埋管地源热泵开发利用现状进行了调查分析。在研究区内一处运行时间长,运行效果良好的地埋管地源热泵工程场地内进行钻探取芯、岩土体样品采集及现场热响应试验,分析工程场地内地层岩性特征、地层初始平均地温、岩土体导热系数等热物性参数。监测地埋管地源热泵机组夏季制冷及冬季供暖时的运行数据,计算热泵机组运行能效比及节能减排效率。对比分析地埋管地源热泵机组与常规方式的制冷与供暖年耗能量,地埋管地源热泵制冷与供暖均起到节能的效果。地埋管地源热泵制冷期节煤率为21%,供暖期节煤率为35%。计算地埋管地源热泵工程静态投资回收期为8年,其运行年限已超过回收期年限。In order to discuss the exploitation and development potential of ground-coupled heat pump in Yinchuan,an investigation was carried out for stratigraphic features and status quo of the ground-coupled heat pump exploitation and development.The research selected a durable and well-run ground-coupled heat pump project to extract stratigraphic features,initial average geothermal and rock-soil mass thermal conductivity and other thermal physical parameters through core drilling,soil sampling and in-situ thermal conductivity test.Monitoring the running data of ground-coupled heat pump unit in summer cooling and winter heating,and calculating the energy efficiency ratio and energy conservation efficiency.Compared the energy consumption between ground-coupled heat pump and conventional refrigeration and heating method,the ground-coupled heat pump could be both energy-efficient.The coal-saving ratio of ground-coupled heat pump in summer was 21%,while in winter was 35%.Finally,a 8-years static payback period of ground-coupled heat pump project was obtained,which illustrated that the operation period was in excess of the payback period.
