摘要
北京某会所5000m2,采用地源热泵系统。本文通过全年负荷模拟计算和地下温度场数值模拟分析两种途径,结合部分工程的热泵机组和输配系统的实际运行效能,优化方案设计并校核设备选型,提高地源热泵系统的安全可靠性,从而达到不进行其他模式冷源或热源备份的目的。
This club building is five thousand meters and equipped with ground source heat pump system(GSHP).In order to reduce initial equipment investment and guarantee the energy efficiency,this article proposed whole year energy simulation and the annual consumption was analyzed.Ground source heat accumulation effect was accurately predicted with the help of simulation toolkits FLUENT.The investigation of real GSHP projects' performance data was carried out to low down the risk of system.
