在夏日因运送气体温度低于周围环境空气露点温度，管道外壁会结露。这对会集空调系统的风道会加大冷量损失，一起凝结水滴会污染吊顶和墙地面，因而也应该进行保冷隔热处理，其实关于通风管道装置施工来说，

In summer, because the temperature of the transported gas is lower than the dew point temperature of the surrounding air, the outer wall of the pipeline will condense. This will increase the cooling capacity loss of the air duct of the centralized air conditioning system, and the condensed water droplets will pollute the ceiling and wall ground. Therefore, the cold insulation treatment should also be carried out. In fact, for the construction of ventilation duct installation,

一般来说，通风体系的流量都很大，因而要求运用阻力较小的空气运送管道，以节省造价和运转费用——通风管道就适用。一般情况下运用镀锌铁管，有腐蚀性及特别潮湿的场所运用不锈钢管。

Generally speaking, the flow of ventilation system is very large, so it is required to use air transportation pipeline with low resistance to save cost and operation cost - ventilation pipeline is applicable. Generally, galvanized iron pipes are used, and stainless steel pipes are used in corrosive and particularly humid places.

一、空调体系：通风管道可内贴保温材料，表面美观。

1、 Air conditioning system: the ventilation duct can be pasted with thermal insulation materials, and the surface is beautiful.

二、排油烟体系：饭店、酒楼、宾馆的厨房均有很多油烟发生，需求排出，采用通风管道是适宜的，强度好，经济实用。

2、 Oil fume exhaust system: many oil fume occurs in the kitchens of hotels, restaurants and hotels, which needs to be discharged. It is appropriate to use ventilation pipes, with good strength, economy and practicality.

三、除尘体系：除尘装置的搜集和运送，可运用通风管道。

3、 Dust removal system: ventilation pipes can be used for the collection and transportation of dust removal devices.

四、散装物料运送：气力运送体系种，一些较细些松散的物料颗粒，可运用通风管道运送，造价低、效果好。

4、 Bulk material transportation: pneumatic transportation system. Some fine and loose material particles can be transported by ventilation pipe, with low cost and good effect.

地下室通风方式合理安置排风管及排风口，平常排风用，火灾时兼作排烟风管及排烟口;地下一层考虑由车道天然进风，其它层由平常送风系统兼作火灾时补风系统。

The ventilation mode of basement shall be reasonably arranged with exhaust pipe and air outlet, which are used for ventilation in ordinary times, and also used as smoke exhaust pipe and smoke outlet in case of fire; The natural air intake from the driveway is considered for the first floor underground, and the ordinary air supply system is also used as the air supplement system in case of fire for other floors.

连接件均采用镀锌件;法兰垫料应用有弹性、不产尘，有强度的软橡胶或者乳胶海绵;风管的外保温采用难燃橡塑板，以专用胶张贴，禁止在施工过程中运用玻璃棉等纤维制品。多个排烟分区合用排烟排风体系，这种状况的话，就是电动阀+排烟风口，平时常开排风，着火封闭非着火点排烟分区的设置在支管上的电动阀。

All connectors are galvanized; Flexible, dust-free and strong soft rubber or latex sponge shall be used for flange gasket; The external insulation of the air duct shall be made of flame-retardant rubber plastic board and posted with special glue. It is forbidden to use glass wool and other fiber products during construction. Multiple smoke exhaust zones share the smoke exhaust system. In this case, it is the electric valve + smoke exhaust outlet. Usually, the exhaust is always open, and the fire is closed. The electric valve set on the branch pipe of the non fire smoke exhaust zone.
