摘要
华东地区是亚热带气候,地源热泵的埋管换热效果等参数与北方地区不同,采用实地测量的方法研究了地源热泵系统在华东地区性能.结果表明,100 m单U型埋地管的每米孔深换热量为56 W/m,地源热泵系统全年总换热量为3 395 000.1 kWh,COP达到3.8,两年可收回系统初投资,是节能、经济的热泵系统.
East China is in subtropical climate region.Heat transfer effect and other parameters of ground-source heat pump pipe are different from those of North China.Based on field measurement,the performances of ground-source heat pump system in East China were analyzed.The results showed 100-meter single U-tube heat transfer was 56 W/m for each hole,the annual heat transfer of the ground-source heat pump system was 3 395 000.1 kWh,the COP reached 3.8,and the initial investment of the system could recover in two years.So this system was energy-efficient and economical heat pump system.
