上海某项目冷热源联合供能系统设计

Design on combined energy supply with cold and heat source of one Shanghai project

根据上海某项目实际功能和特点,结合绿色建筑认证等节能要求,提出采用冰蓄冷+电蓄热+水蓄冷+免费制冷的联合供能系统,采用融冰优先控制策略和多种工况切换控制,可适应各种负荷需求,最大限度地提高能源利用率和节省能耗。

Based on the practical function and its characteristics of one Shanghai pro- ject,as well as the energy saving requirement of LEED certification, the combined energy supply system consisting of ice storage, electric heat-storage, chilled water storage and free refrigeration is proposed. This system can meet a variety of load demand and maximize energy utilization and energy-saving through using the ice defrosting priority control strategy and multiple operation condition＇s switching control.
