Central Air-conditioning System Design for Mingzhu Hotel of Shanghai

根据不同功能房间,集中空调系统分为三种空调送风方式,高大空间如餐厅、娱乐室等采用全空气系统,新风直接从室外引进与回风混合后送风;而会议室、技师房等采用了空调机组加独立新风方式,新风经独立处理后进入空调机组和回风混合处理后送风;其他小空间房间采用了风机盘管加独立新风系统,新风机组从室外引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.楼梯间采用自然排风排烟,电梯间前室设置加压送风装置,地下室设备房设置防排烟系统,采用同一个系统,选用双速风机,平时排风,发生火灾时排烟.

The conditioning system is divided into three different systems according to its function. The first one is the high and big room such as restaurant, and the second one is the meeting room,and the third is the other little rooms such as office,bedroom,KTV room and so on. The first system adopts the complete air system. The air - conditioning equipment deals with the supply and the air return. The second system uses the PAU ＋ AHU system, AHU system deals with the returning air, and PAU system deals with the fresh air. The third system adopts the PAU ＋ FCU system, FCU system deals with the returning air. Natural ventilation is used in the hall and the rooms which can prevate air out. And almost all rooms＇ returning air is through the floor. The design adopts the same system to exhaust air and smoke, and the dualwind velocity fans are chosen. Ordinarily, it only exhaust air, it does not exhaust smoke unless the fire disaster happened.
