1、 1 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入各房间，送

2、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 ：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 is 13 co

3、nstructs, 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 angle co

4、nsideration, 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 gu

5、sty 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, package) because the area is smaller, Uses the air blower plate tube to add the new atmosphere system, Outside the n

6、ew atmosphere will process to is lower than in the room the air enthalpy value condition, Undertakes in the room completely the wet load and the partial cold loads, The new atmosphere by establishes the suspended ceiling new atmosphere unit processes after the corridor sends in various rooms, The bl

7、ast uses double-decked drifting delivers the gusty area, The air blower plate tube blast selects the side to deliver the type, installs the form for the horizontal-type dark attire. The Air conditioning refrigeration engine room is located in the basement, Selects two screw rods types cold water uni

8、t, Summer uses 7/12 cold water which the cold water unit provides, Winter the heat interchanger future since will concentrate the boiler room 95/70 water transformation is 60/50 hot water, Sends in various rooms, The water pipeline uses two. The cooling tower sets to the roof, each cold water unit respectively matches. Key word: Air conditioning design, entire air system, air blower plate tube system, cold water unit.
