4.1 Unit 空调箱

4.1.1 General requirement通用要求

The HVAC cooling media is 6~12℃ chilled water, from black utility system. 暖通空调系统冷源为6~12℃冷冻水，来自公用系统。

The HVAC heating media is 60~50℃ hot water, from black utility system. 暖通空调系统热源为60~50℃热水，来自公用系统。

The HVAC humidifier media is 0.2MPa clean steam, from clean utility system. 暖通空调系统加湿器采用0.2Mpa洁净蒸汽，来自公用系统。 All the inlet and outlet of the AHU should be with manual damper by AHU supplier.

所有空调箱的及出口须由空调箱的供应商提供手动风阀。

For the AHUs which have no coil, the velocity of the section should no more than 2.5m/s.

对于所有无盘管的空调箱，空调箱的断面风速不得大于2.5m/s。

4.2 Unit Casing箱体

4.2.1 All AHUs should have no-through-metal on all wall, floor, doorframe, and ceiling

sections and doors. AHU designated to operate at locations with high temperature and humidity conditions shall have a true thermal break construction. A thermal break should be equivalent to an epoxy bridge. Tape, caulk, paint, gaskets, or similar items are considered unacceptable as a true thermal break.

所有机组需提供由连续的金属制作的墙板，底板，门框和顶板以及门。空调箱须具有满足在高温高湿工况下运行的保温性能。任何位于框架，胶条，填缝，涂层，垫圈或类似的部分发生的热传导将不被接受。

4.2.2 For walls and ceiling, the casing panel skins shall be a minimum 1.0mm thick zinc

coated steel with powder coated on external & inner surfaces.

对于机组侧壁和顶板，箱体板材应为至少1.0毫米后的镀锌钢板，外表面和内表面均要进行粉末喷涂处理。

4.2.3 Floors of units shall be minimum 1.0mm thickness galvanized steel sheet with

colour powder coating on external and inner surfaces, adequately supported to ensure no buckling or deformation takes place as a result of maintenance foot traffic.

机组的底部应为最小1.0毫米厚的镀锌钢板，外表面和内表面均要进行粉末喷涂处理，加固良好以确保无弯曲或变形产生。

4.2.4 The internal surfaces of all sections shall be constructed with stainless steel 304

material. The thickness should be no less than 1mm.

机组所有功能段的内表面采用SS304不锈钢材料制造，不锈钢材料的厚度不得小于1.0毫米。

4.2.5 Insulation shall be continuous at joints and corners to eliminate all paths for cold

tracking. All rivets used in the construction of the casing shall be of the sealed type.

保温应确保在联结和转角处保持连续，以消除冷桥，所有用于外科制作的铆钉应为封闭型。

4.2.6 All the unit casing panels and doors shall be designed to prevent from “cold

bridge”. The insulation shall be PU or rockwool and the performance of all the

panels & doors shall comply with thermal bridging factor of TB2 Class and thermal transmittance performance of T2 Class as per EN1886. TB2:0.6?Kb≤0.75, T2: 0.5?u≤1 w/m2k.

所有的机组面板和门板均应为防冷桥设计。保温材料应为岩棉，所有面板和门板的隔热性能应符合欧洲EN 1886标准所规定的T2标准，防冷桥系数应同时满足该标准中所规定的TB2的要求。（TB2:0.6?Kb≤0.75, T2: 0.5?u≤1 w/m2k） 4.2.7 The unit panels shall be removable with the thickness of no less than 45mm and

shall not cause condensation in operation environment.
