1、摘 要本设计为武汉某院门诊楼空调系统设计，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与热负荷，每个房间的吊顶内安置一到二个风机盘管。新风则由新风机组处理后通过独立的新风管道先送入风机盘管，再与回风混合一起送入房间。新风机组吊顶安装，每一层楼安装一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占用建筑面积少，可集中供冷和供热；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，并且防止了空气的交叉感染。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。本次设计的建筑对象位于武汉市
2、,该建筑的楼层结构为地上八层，总建筑面积约为 6500 m2，其中设计空调面积 4500m2，空调总冷负荷为 660kw，单位面积冷指标为 146W，单位面积热指标为 110W。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：空调系统； 风机盘管加新风系统； 性能比较； 末端设备ABSTRACTThis air-conditioning systems design for the Wuhan Tumor Hospital out-pa
