1、毕业设计说明 0摘要摘要本设计为沈阳塘栖大厦，使用性质是商业办公楼,地下一层，地上六层，总建筑面积是 19700 平方米。其中地下室为车库，地上一层为酒店餐厅，二层为酒店包厢，三层为 KTV 包厢，四层为会议室和棋牌室，五层为游泳馆，六层为客房。建筑总高度是28.2 米，使用年限是 100 年。本设计为沈阳塘栖大厦暖通空调工程设计，拟为之设计合理的中央空调系统，为室内人员提供舒适的工作环境。系统主要采用风机盘管承担空调房间的冷负荷，每个房间的吊顶内安置一到二个风机盘管。新风则通过独立的新风管道送入房间。新风机组吊顶安装，每一层楼安装两台新风机组负担该层所有空调房间的新风负荷。该空调系统的优点是
2、占用建筑面积少，可集中供冷；同时各末端装置有独立的开关和调节功能，各房间的温度可独自调节与控制。空调水系统采用闭式系统,因为它除了不易污染,节省初投资外,还具有很大的节能效果。对于大厅等少数房间采用了全空气一次回风系统。同时地下车库进行了通风排烟的设计。本设计内容包括：空调冷热负荷计算；空调系统的确定及论证；送风状态参数及送风量的确定；空气处理设备的选型；冷热源的选择及设备选型；气流组织计算；水力计算；其他设备的选择；保温与防腐以及减振和消声等内容。关键字关键字：空调系统；全空气系统；风机盘管加新风系统；机械通风1AbstractThis design as you start buildin
