1、某 10 层大厦暖通空调、通风、防排烟设计1某某 10 层大厦暖通空调、通风、防排烟设计层大厦暖通空调、通风、防排烟设计摘摘 要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用一次回风集中式中央空调系统，其余场所采
2、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 40Pa50Pa，消防前室设置正压为25Pa30Pa。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，风机盘管系统，机械排烟某 10 层大厦暖通空调、通风、防排烟设计2AbstractThe building is located in Nan
