北京某国际大酒店空调工程毕业设计（计算书+图纸）

毕设基本摘要
摘要
本设计为上海华信国际大酒店空调工程设计，本人负责地下一层和四层部分。通过方案比较，在负荷计算的基础上，采用了风机盘管加新风和全空气两种空调系统形式。风机盘管为卧式暗装，新风不承担室内负荷，室内回风与新风混合后经双层百叶风口送出；全空气系统为一次回风系统，室内送风采用侧送风方式，风口为双层百叶风口。新风从墙洞或新风竖井引入，再由机房的新风机组集中处理供应。冷冻水由地下室的冷冻机房供应，采用了闭式异程两管制水系统。水管用泡沫橡塑保温，风管采用离心玻璃棉。设计工程中考虑了消声、减振和防火排烟的措施。

Air Conditioning Design of Shanghai Huaxin International Hotel
ABSTRACT
The air conditioning engineering of the -1F and 4F of Shanghai Huaxin International Hotel was designed. On the base of cooling load, heating load and moisture load calculation, primary air fan-coil system and all air system are adopted by way of technical and economic analysis. The fresh air doesn’t undertake indoor load and delivers air through double deflection grille after mixing the return air in the horizontal recessed fan coil. The return air is harnessed one time by the air handling unit in the all air system and the handled air is delivered through double deflection grille by sidewall air supply. The fresh air is supplied by hole or shaft and handled by the fresh air handling unit. The chilled water which is a closed two-pipe direct return water system is supplied by the refrigerating plant room. The thermal insulation material of water pipe and air duct are foam plastics and centrifugal glass wool respectively. Measures of noise elimination, damp, fire prevention and smoke extraction is considered during the design.
Key Words: air conditioning; primary air fan-coil system; all air system; fresh air
