摘要本次毕业设计课题为重庆市某综合楼空调工程设计,工程建筑面积 42529 平米。地下2层,地上7层,总高 32.5米,属于中高层建筑。其中地下二层为车库,战时为人防,地下一层为超市和制冷机房,一到四层为商场,五到七层为办公用房。 本次设计在结合重庆市气候以及本建筑的负荷情况之后,采用了水冷式冷水机组为冷源,燃气热水锅炉为热源。因为本建筑层高较低,考虑到经济效应,采用竖直异程水平异程两管制单级泵闭式水系统。地下一层到地上四层大空间采用全空气系统,五到七层采用风机盘管加独立新风系统。全空气选用方形平送风散流器,风机盘管采用侧送风,无法侧送风的采用顶送风。卫生间通风统一设置排气扇排至排风竖井,排风管出口设止回阀,屋顶排风井采用风帽排风。地下二层通风排烟系统选用双速风机,平时通风,发生火灾时候送风排烟。 25883

 Title    Design of the air-conditioning engineering for a complex building in Chongqing                           
 Abstract
The graduation project is a complex building air conditioning engineering design
in Chongqing,  for  construction area of 42,529 square meters.  Building underground
is  two  stories  and ground is  seven  stories,  with a total height 32.5 meters, belongs
to mid-rise buildings. which is usually a ground floor is a garage, in wartime
to staff the shelter by a second-class, one to four shopping malls, five to seven
for the office space.
In this design, in combination with Chongqing weather and load conditions of the
building, Water chiller  is used as  cold source, gas hot water boiler  as  heat  source.
Because of the lower floors of the building, taking into account the economic
effects,  control the single-stage pump with the vertical different level two
control single-stage pump closed water system. Underground one to the ground to
the four layer of large space adopt the all air system, Five to the seven layer
using fan coil plus fresh air system independent. All air system choose a square
flat air diffuser, the fan coil adopts the side air supply side, and can not send
the wind by the wind blowing. Ventilation and ventilation in the bathroom is
arranged to exhaust ventilation fan, exhaust pipe outlet valve located, roof exhaust hood
exhaust well use. Underground two layer ventilation exhaust systems use two-speed fan, ormal
ventilation, air exhaust when fire
