利用De ST软件计算分析了南京某大型办公建筑的全年动态负荷特点,基于土壤热平衡原则确定了该地源热泵项目的冷热源方案。该项目利用新风热回收技术大幅减少了冷热源系统需承担的建筑负荷,冷水机组+冷却塔与地埋管换热器联合的系统形式方便了运行管理,可为类似的大型公共建筑地源热泵空调系统方案设计提供参考。 De ST software was used to calculate and analyze the annual dynamic load characteristics of a large office building in Nanjing. Based on the principle of soil thermal balance, the scheme of cold and heat source was determined. The project uses fresh air heat recovery technology to significantly reduce the cold and heat source system to bear the building load, chiller + cooling tower and buried pipe heat exchanger system to facilitate the operation of the joint management of similar large-scale public buildings Heat pump air conditioning system design for reference.
