南京市土壤源热泵系统建筑应用特点分析

Analysis of Ground-coupled Heat Pump System Architecture Application Characteristics in Nanjing

文章根据南京市20个土壤源热泵系统可再生能源能效测评数据,统计分析了土壤源热泵系统地下换热形式及换热量、增量成本、机组性能系数、系统能效比、全年常规能源替代量、年节约费用和静态投资回收期等参数特点。研究得到了土壤源热泵系统在南京市(夏热冬冷地区)建筑中应用的特点及相应的关键参数,为该技术在南京市规模化推广和应用提供了科学的参考依据。

According to the renewable energy evaluahon data o! 20 ground-coupled heat pump systems m Nanjing, statistical analysis were applied on parameters including the combination characteristics of ground- coupled heat pump system and architecture type, underground heat transfer form and capacity, system incremental cost, coefficient of performance, energy efficiency ratio, annual conventional energy alternative amount, annual cost saving, static investment payback period, etc. The key parameters and characteristics of ground-coupled heat pump system application in Nanjing （hot summer and cold winter area） architectures were obtained, as scientific reference basis for the large-scale popularization and application in Nanjing.
