1、某10层大厦暖通空调、通风、防排烟设计某10层大厦暖通空调、通风、防排烟设计摘要本建筑位于江苏省南京市,是一栋楼层为10层,集餐饮、娱乐、住宿和地下车库为一体的综合性建筑物。本设计旨在对该大厦进行空调、通风与防排烟设计,力求达到经济、舒适、实用,并尽可能满足节能的要求。总建筑面积17300m2,空调面积约8179m2。夏季设计冷负荷为1209kW,是一项能耗较大的工程。本工程采用水冷螺杆冷水机组作为空调的冷源进行夏季制冷,冬季采用热水锅炉进行供暖。通过对各种空调方式的比较,精品商店等大空间区域采
2、用一次回风集中式中央空调系统,其余场所采用吊顶风柜或独立新风加风机盘管等半集中方式。该大厦一至三楼东、西侧空调区域分别共用一个冷冻水环路,四至十层共用另一冷冻水环路。建筑内走道采用竖井排烟,排烟风机设置在10层;中庭通过在裙楼屋顶层采光棚旁设置风机来实现排烟;防烟楼梯间和消防前室进行机械送风来保证疏散安全,其中防烟楼梯间设置正压为40Pa~50Pa,消防前室设置正压为25Pa~30Pa。地下车库采取车道自然补风,设置机械排风、排烟。卫生间均采用通风器进行排风。关键词:水冷螺杆冷水机组,节能,风机
