在夏日因運送氣體溫度低于周圍環(huán)境空氣露點溫度，管道外壁會結(jié)露。這對會集空調(diào)系統(tǒng)的風(fēng)道會加大冷量損失，一起凝結(jié)水滴會污染吊頂和墻地面，因而也應(yīng)該進(jìn)行保冷隔熱處理，其實關(guān)于通風(fēng)管道裝置施工來說，

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,

一般來說，通風(fēng)體系的流量都很大，因而要求運用阻力較小的空氣運送管道，以節(jié)省造價和運轉(zhuǎn)費用——通風(fēng)管道就適用。一般情況下運用鍍鋅鐵管，有腐蝕性及特別潮濕的場所運用不銹鋼管。

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、空調(diào)體系：通風(fēng)管道可內(nèi)貼保溫材料，表面美觀。

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

二、排油煙體系：飯店、酒樓、賓館的廚房均有很多油煙發(fā)生，需求排出，采用通風(fēng)管道是適宜的，強度好，經(jīng)濟實用。

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、除塵體系：除塵裝置的搜集和運送，可運用通風(fēng)管道。

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

四、散裝物料運送：氣力運送體系種，一些較細(xì)些松散的物料顆粒，可運用通風(fēng)管道運送，造價低、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.

地下室通風(fēng)方式合理安置排風(fēng)管及排風(fēng)口，平常排風(fēng)用，火災(zāi)時兼作排煙風(fēng)管及排煙口;地下一層考慮由車道天然進(jìn)風(fēng)，其它層由平常送風(fēng)系統(tǒng)兼作火災(zāi)時補風(fēng)系統(tǒng)。

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.

連接件均采用鍍鋅件;法蘭墊料應(yīng)用有彈性、不產(chǎn)塵，有強度的軟橡膠或者乳膠海綿;風(fēng)管的外保溫采用難燃橡塑板，以專用膠張貼，禁止在施工過程中運用玻璃棉等纖維制品。多個排煙分區(qū)合用排煙排風(fēng)體系，這種狀況的話，就是電動閥+排煙風(fēng)口，平時常開排風(fēng)，著火封閉非著火點排煙分區(qū)的設(shè)置在支管上的電動閥。

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.
