毕设基本摘要
摘 要:本设计为广州中央空调系统工程设计，共十二层，地下两层，建筑总面积13000 ，空调面积6526.6 ，根据房间功能，全楼采用集中供给空调方式，制冷机组采用直燃型溴化锂吸收式制冷机组两台，型号分别为BZ-40单台制冷量分别为465KW.
根据各不同功能房间，将该集中系统分为二种空调送风方式，高大空间如餐厅、活动用房等采用全空气系统，新风直接从室外引进与回风混合（一次回风）后送风；住户、公寓等采用了风机盘管加独立新风系统，新风机组从室外引入新风处理到室内空气焓值，风机盘管承担室内全部冷负荷及部分的新风湿负荷。全空气系统选用圆型散流器平射流形式，而风机盘管加独立新风系统有百叶风口侧送和散流器平送的形式。水系统采用闭式双管同程式，冷水泵三台，两用三备，；冷却水泵选三台，两用一备。卫生间通风统一由排风扇接出，在末端安装止回阀。楼梯间采用自然排风排烟；标准层以上由于小于500m2所以采用自然排风；地下室、设备房、一层及二层设置防排烟系统，，选用变速风机，平时排风，发生火灾时排烟。
空调水系统只设有一个系统， 每层均设有回水同程管。

Abstract:This design is about the central air conditioner engineering of Yingcai Hotel that locates in Beijing. There are 12 floors and two floor underground. The gross floor area is about 13000m2,and the air conditioner area is about6526.6. The cold duty is 874kw, We choose 2 immediate-combustion and absorption LiBr, and the models are BZ40H.Their maximal burning of natural gas are 465kw when refrigerating; According to different functions, The first system is in the high and big space such as restaurant, KTV room, meeting room, market ect. It adopts the complete air system. The air-conditioning equipment deals with the fresh air and then supplies air. The second system is in other little room. It adopts the PAU+FCU system. FCU system deals with the fresh air. PAU system carries on the whole cold duty and part wet duty. PAU+FCU systems can send air from the side and the upside; it uses the circular air diffuser to supply air. There are five water-cooling pumps; three can be used when heating. In summer, two of five are for using and another three are for preparing; in winter, two for using and one for preparing. The system in washroom can ventilate by itself. The system in the staircase and the standard floors can exhaust air and smoke by itself. The preventing and exhausting smoke system is used for the underground room, the equipment room and the first and second floor and it adopts the same way to exhaust air and smoke: choosing the dual wind velocity fans which exhaust air at ordinary times, while exhausting smoke when the fire disaster happens. The water system is divided into four parts: the first part is the underground room, the second part is the equipment room, the third part is the first and second floor, the fourth part is the standard floors that is the third floor and above.. Keywords: PAU+FCU systems, complete air system, preventing and exhausting smoke, air diffuser, refrigeration machine
