摘　　要：为提升科技住宅中地源热泵系统的地热能源利用效率,依托中国铁建·花语湖畔项目,从地源热泵系统的地埋管能源端、空调末端、自控系统和能耗监督管理系统端进行研究,通过方案比选、设备选型、数据计算对其进行节能效果评估和经济性分析。结果表明:采用双U管换热器单井制冷量比单U管换热器高出11.1%;选用的螺杆式地源热泵机组年运营费用比常规螺杆式水冷冷水机组减少11%,磁悬浮变频离心式冷水机组的年运行成本仅为常规定频水冷离心式冷水机组的66%;低温辐射末端加置换式新风的温湿度独立控制系统比常规空调(风盘+地暖)系统能耗降低30%以上;通过自动控制及能耗监督管理系统可使整个系统的综合能效提高10%以上。本研究对地源热泵系统的能效提升具有参考意义。In order to improve the geothermal energy utilization efficiency of the ground source heat pump system in the science and technology residence,this study relies on the China Railway Construction·Huayu Lakeside Project,and conducts research on the buried pipe energy end,air conditioning end,self⁃control system,and energy consumption supervision and management system end of the ground source heat pump system.Through scheme comparison,equipment selection,and data calculation methods,the energy⁃saving effect evaluation and economic analysis are carried out.The results show that the cooling capacity of single well with double U⁃tube heat exchanger is 11.1%higher than that of single U⁃tube.The annual operating cost of the selected screw⁃type ground source heat pump unit is 11%lower than that of the conventional screw⁃type water⁃cooled chiller,and the annual operating cost of the magnetic suspension frequency conversion centrifugal chiller is only 66%of that of the conventional fixed frequency water⁃cooled centrifugal chiller.The temperature and humidity independent control system with replacement fresh air at the end of low temperature radiation reduces the energy consumption by more than 30%compared with the conventional air conditioning(air plate+floor heating)system.The comprehensive energy efficiency of the whole system can be improved by more than 10%through automatic control and energy consumption supervision and management system.This study has reference significance for the energy efficiency improvement of ground source heat pump system.
