复合式地源热泵系统在青岛科技馆项目中的应用

根据青岛科技馆建筑负荷特点及项目周围能源分布、运营时间,介绍了复合式地源热泵系统(冬季采用燃气锅炉辅助调峰供暖,夏季选用冷水机组+冷却塔系统辅助供冷)的冷热源系统配置思路,并从初投资、运行费用、静态回收期等方面分析了其应用合理性.为了降低系统运行能耗,根据科技馆动态负荷和机组运行特性对复合式地源热泵的控制策略进行了初步...

Application of compound ground-source heat pump system to Qingdao Science and Technology Museum

According to the construction load characteristics of Qingdao Science and Technology Museum,the distribution of energy around the project and the operation time,this paper presents the configuration ideas of the cold and heat source of the combined ground-source heat pump system(gas boiler for auxiliary peak-shaving heating in winter,and chiller plus cooling tower system for auxiliary cooling in summer),and analyses the application rationality from the aspects of initial investment,operating costs,static payback period,etc.In order to reduce the energy consumption of the system,this paper carries out a preliminary study on the control strategy of the compound ground-source heat pump according to the dynamic load of the Qingdao Science and Technology Museum and the operating characteristics of the units,with a view to provide guidance for the application of the compound ground-source heat pump system to actual projects.
