重庆万达文化旅游城万达茂给排水设计总结

Summary of water supply and drainage system design of Wanda mall in Chongqing

重庆万达文化旅游城万达茂为集商业街和室内水乐园、海洋乐园、娱雪乐园于一体的大型城市综合体,着重分析了室内乐园大空间及冷区的消防给水系统等设计重难点。室内乐园的大空间通过引入“防火隔离带”概念,采用了自动灭火系统覆盖整个“防火隔离带”及“防火控制区”,冷区设置了干式消防给水系统。室内乐园的热水系统充分利用可再生能源,采用了余热回收及风冷热泵系统等预热系统。并对给水、排水及消防系统在供水方式、点位布置、系统选择、管线排布等方面的设计经验进行了总结。

Wanda mall in Chongqing is a large complex that integrates commercial streets,indoor water park,ocean park,and snow park,this paper mainly analyzed the design points of fire extinguishing systems for lager space areas and cold areas of indoor parks.The lager space areas of indoor parks set up the"fire isolation zone",the design adopted automatic fire extinguishing systems to protect the entire"fire isolation zone"and"fire control zone",the cold areas of indoor parks set up the dry fire extinguishing system.The hot water system of indoor parks utilized renewable energy,the design adopted preheating system such as waste heat recovery and air source heat pump system.And summarized the design experiences of water supply and drainage systems,and fire extinguishing systems in terms of water supply methods,drainage point location,system selection,and pipe arrangement.
