一、通風(fēng)管道核心知識

1、 Core knowledge of ventilation ducts

主要類型

Main types

矩形風(fēng)管：空間利用率高，適用于建筑層高受限場景（如商場、辦公樓）。

Rectangular duct: With high space utilization, it is suitable for scenarios with limited building height, such as shopping malls and office buildings.

圓形風(fēng)管：氣流阻力小，適合長距離送風(fēng)或高壓系統(tǒng)（如工業(yè)排風(fēng)）。

Circular duct: with low airflow resistance, suitable for long-distance air supply or high-pressure systems (such as industrial exhaust).

螺旋風(fēng)管：自帶加強筋，強度高且漏風(fēng)率低，常見于潔凈室或?qū)嶒炇摇?/p>

Spiral air duct: equipped with reinforcing ribs, high strength and low air leakage rate, commonly found in clean rooms or laboratories.

軟管風(fēng)管：柔性可彎曲，用于臨時通風(fēng)或設(shè)備連接（如施工排煙）。

Flexible hose duct: Flexible and bendable, used for temporary ventilation or equipment connection (such as construction smoke exhaust).

材質(zhì)選擇

Material selection

鍍鋅鋼板：經(jīng)濟耐用，需防潮處理（適用80%常規(guī)場景）。

Galvanized steel plate: economical and durable, requiring moisture-proof treatment (suitable for 80% of conventional scenarios).

不銹鋼：耐腐蝕、耐高溫，用于廚房排煙、化工廠等特殊環(huán)境。

Stainless steel: corrosion-resistant and high-temperature resistant, used in special environments such as kitchen smoke exhaust and chemical plants.

玻璃鋼（FRP）：抗酸堿、絕緣，適合實驗室或沿海高鹽霧區(qū)域。

Fiberglass reinforced plastic (FRP): resistant to acid and alkali, insulated, suitable for laboratories or high salt spray areas along the coast.

復(fù)合風(fēng)管（酚醛/聚氨酯）：保溫隔音一體化，用于醫(yī)院、數(shù)據(jù)中心等靜壓箱需求場景。

Composite air duct (phenolic/polyurethane): Integrated insulation and sound insulation, used in static pressure box demand scenarios such as hospitals and data centers.

關(guān)鍵參數(shù)

key parameter 

風(fēng)速控制：主風(fēng)管8-12m/s（民用），15-20m/s（工業(yè)）；支管5-8m/s。

Wind speed control: main air duct 8-12m/s (civilian), 15-20m/s (industrial); Branch pipe 5-8m/s.

壓力等級：低壓（≤500Pa）、中壓（500-1500Pa）、高壓（>1500Pa）。

Pressure rating: low pressure (≤ 500Pa), medium pressure (500-1500Pa), high pressure (>1500Pa).

二、設(shè)計規(guī)范與標(biāo)準(zhǔn)

2、 Design specifications and standards

中國標(biāo)準(zhǔn)

Chinese standards

《GB 50243-2016 通風(fēng)與空調(diào)工程施工質(zhì)量驗收規(guī)范》

GB 50243-2016 Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering

《GB 50736-2012 民用建筑供暖通風(fēng)與空氣調(diào)節(jié)設(shè)計規(guī)范》

GB 50736-2012 Design Code for Heating, Ventilation and Air Conditioning of Civil Buildings

三、安裝技術(shù)要點

3、 Key points of installation technology

施工原則

Construction principles

優(yōu)先布置主干管，減少彎頭與變徑（彎頭曲率半徑≥1.5倍管徑）。

Prioritize the arrangement of main pipes and reduce bends and diameter changes (bend curvature radius ≥ 1.5 times the pipe diameter).

與電纜橋架間距≥0.3m，交叉時風(fēng)管在上方（防止冷凝水滴落）。

The distance between the cable tray and the air duct should be ≥ 0.3m, and the air duct should be above when crossing (to prevent condensation water droplets from falling).

連接方式

Connection method

法蘭連接：高壓系統(tǒng)首選，需密封膠條+螺栓緊固。

Flange connection: preferred for high-pressure systems, requiring sealing strips and bolt fastening.

插接式：快速安裝，適用于低壓復(fù)合風(fēng)管。

Plug in type: quick installation, suitable for low-pressure composite air ducts.

焊接：不銹鋼風(fēng)管特殊節(jié)點處理（如排煙系統(tǒng)高溫段）。

Welding: Special node treatment for stainless steel air ducts (such as high-temperature sections of smoke exhaust systems).

減震與保溫

Shock absorption and insulation

風(fēng)機進出口設(shè)軟連接（防火帆布或橡膠），支架加裝減震墊。

Install soft connections (fireproof canvas or rubber) at the inlet and outlet of the fan, and install shock-absorbing pads on the bracket.

保溫層厚度按防結(jié)露計算（如南方地區(qū)≥30mm橡塑保溫）。

The thickness of the insulation layer is calculated based on anti condensation measures (such as rubber insulation with a thickness of ≥ 30mm in southern regions).
