本设计为上海协和医院空调通风系统设计。

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风机盘管。新风则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。

本设计内容包括：空调冷负荷、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；气流组织计算；空气处理设备的选型；冷热源的选择管径选取及水力计算；风管水力计算；及设备选型；其他设备的选择；保温与防腐以及减振和消声等内容。

Abstract

The program for the air conditioning and ventilation system design of Shanghai Xiehe hospital.
    Cooling load and thermal load system mainly adopt fan-coil unit assume air conditioning room, each room fan coil placed inside the ceiling. Fresh air into the fan coil first through independent air pipes, and the air mixed together into the room. Installation of ceiling air supply unit, the wind load on each floor to install a fresh air unit burden the layer of all air conditioning rooms. The advantages of the air conditioning system is reduce the building area, central cooling and heating; and the terminal device is independent of the switch and the regulating function, the room temperature can be adjusted alone and control, and to prevent cross infection in the air. The closed system of air conditioning water system uses, because in addition to its not easy to pollution, save the initial investment, but also has great energy-saving effect.
     The design includes: the cooling load, heat load calculation and demonstration; air conditioning system; air state parameters and determine the air flow rate of air flow organization; calculation; selection of air treatment equipment; selection of pipe diameters of cold and heat source selection and hydraulic calculation of wind pipe; hydraulic calculation; and selection of equipment; equipment selection; heat preservation and anti-corrosion and vibration and noise etc..
