1、 1 摘要摘要 本设计是成都*饭店综合楼中央空调设计,该饭店为十三层建筑,并设有地下室, 总建筑面积 12351m2,总层高 43m。 空调设计中,一、二层的大空间(商场、大堂、大堂吧等)采用全空气一次回风的 空气处理方案,从节能的角度考虑,采用露点送风。空气处理机组设在每层的空调机房 内,新回风经集中处理后送入各空调房间。气流组织采用上送上回的气流组织形式,送 风口选用方形散流器,回风口采用单层百叶回风口。 其余空调房间(办公室、客房、包间)因面积较小,采用风机盘管加新风系统,将 室外新风处理到低于室内空气焓值的状态,承担室内全部湿负荷和部分冷负荷。新风由 设置在走廊内的吊顶新风机组处理后送
2、入各房间,送风采用双层百叶送风口。风机盘管 送风选用侧送式,安装形式为卧式暗装。 空调用制冷机房设在地下室,选用两台螺杆式冷水机组。夏天使用冷水机组提供的 7/12的冷水,冬天由换热器将来自集中锅炉房的 95/70的锅炉供水转换为 60/50的 热水后,送入各房间。水管路采用两管制。冷却塔置于屋顶,每台冷水机组各配一台。 关键字关键字:空调设计,全空气系统,风机盘管系统,冷水机组 2 Abstract This design is the Chengdu *hotel synthesis building central air conditioning design, This hotel
3、is 13 constructs, And is equipped with the basement, Total floor space 13000m2.Total building store height 43m. In air conditioning design, 1F and 2F big spaces (market, great hall, great hall and so on) use the entire air time to return to the wind the air processing plan, From energy conservation
4、angle consideration, Uses the dew point blast. The air processing unit is located in each level in the air conditioning engine room, New、returns to the wind to send in various air conditioned room after centralism processing, The air current organization form used on delivers the other day, Delivers the gusty area to select square shape drifting. Returns to the gusty area to use the monolayer drifting to return to the gusty area, Other air conditioned rooms (example office, guest room, pa
