摘要本设计为苏州市某办公楼空调工程设计，本工程是9层的建筑。主要用作办公室，地上一层有一营业大厅，三楼及以上主要为办公室。通过方案比较，在负荷计算的基础上，采用了吊顶机组加新风和全空气两种空调系统形式。新风不承担室内负荷，室内回风单独处理，与新风混合后送出；全空气系统为一次回风系统，室内送风采用顶送风方式，风口为方形散流器风口。新风系统的新风从墙洞或新风竖井引入，由新风机组集中处理供应。冷冻水由地下室的冷冻机房供应，采用了闭式同程两管制水系统。水管用泡沫橡塑保温，风管采用离心玻璃棉。设计工程中考虑了防排烟的措施。 关键词：空调；吊顶机组加新风系统；全空气系统；新风9396

Title Air conditioning design for a office building in Suzhou
Abstract
This design for a Suzhou office building air conditioning engineering design, this project is building 9 layers. Mainly used as office purposes, the ground layer is business lobby，three to nine layers are room. On the base of cooling load, heating load and moisture load calculation, Ceiling air conditioning units and rush air 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 the pipe that is different from the return air but both pushed out through double deflection grille. The return air is harnessed one time by the air handling unit in the all air system and the handled air is delivered through square supply openings by top wall 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 indirect 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.Smoke extraction is considered during the design.
Keywords：air conditioning; Ceiling air conditioning units and rush air system; all air system; fresh air
