文档介绍：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,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。

ABSTRACT
This air-conditioning systems design for the Wuhan Tumor Hospital out-patient floor design it to be a reasonable central air-conditioning system for indoor staff provide fortable working environment.
Fan-coil system is mainly used air-conditioned rooms bear the cooling load and the heat load, the ceiling of each room placement within 1-2 fan-coils. The new wind of fresh air through independent channels into the first fan-coil, and then mixed together with return air into the room. New wind generating units installed on ceiling, each floor to install a new air unit of the burden of all air-conditioned rooms in the new wind load. The air-conditioning system has the advantage of occupying less floor space, cooling and heating can be concentrated at the same time, the terminal device and a separate regulatory function switch, the room temperature alone can regulate and control, and prevent cross-infection of the air. Air-conditioning system uses closed-water systems, not because it apart from pollution, save initial investment, but also has great energy-saving effect.
Thedesign of the building object is located inWuhanCity,basement floor eight layers with a total construction area of about 6500, the total air-conditioning cooling load for the 660KW, per unitarea of cold indicators 146W, unit area heat index of 110W.
The design elements include: hot and cold air-conditioning load calculation; air-conditioning system and the determination of p
