風管的種類 風管與空調的區(qū)別
Types of air ducts Differences between air ducts and air conditioners
空調風管的材質有哪些，地鐵工程用哪種材質合適？
What are the materials of the central air conditioning duct, and which is suitable for the subway project?
一般空調風管材料有兩種，一種是玻璃鎂復合板風管，重量輕，強度高，不燃，隔音，可用于潮濕環(huán)境；另一種是彩鋼板保溫復合風管，是目前傳統(tǒng)玻璃鋼風管和新一代鍍鋅鐵風管的換代產品?？朔艘酝ＡЮw維風管強度弱、易損傷外壁的致命弱點，弘揚了鍍鋅鐵的優(yōu)點。并且剛性非常好。當然，還有其他的空調風管材料，比如酚醛鋁箔復合風管和聚氨酯鋁箔復合風管都是好的空調風管，主要是根據具體情況來選擇合適的空調風管。風管，盡量選擇強度高、質量好、不重、耐熱、防潮的空調風管，使用壽命長。
Generally, there are two kinds of air duct materials for air conditioners. One is glass magnesium composite panel air duct, which is light in weight, high in strength, incombustible and sound proof, and can be used in humid environments; The other is color steel insulation composite air duct, which is a replacement of the current traditional FRP air duct and the new generation of galvanized iron air duct. It overcomes the fatal weakness of weak strength and easy damage of the outer wall of the glass fiber air duct in the past, and carries forward the advantages of galvanized iron. And the rigidity is very good. Of course, there are other air conditioning duct materials, such as phenolic aluminum foil composite duct and polyurethane aluminum foil composite duct, which are good air conditioning ducts, and they are mainly selected according to the specific situation. The air duct shall be of high strength, good quality, light weight, heat-resistant and moisture-proof, with a long service life.
空調風管按制作材料可分為哪些類型？各自的優(yōu)點和缺點是什么？
What types of air conditioning ducts can be classified according to the materials? What are their advantages and disadvantages?

常用的風管材料有哪些
What are the common air duct materials
風管按材質可分為金屬風管、復合風管和聚合物風管。
The air duct can be divided into metal air duct, composite air duct and polymer air duct according to the material.
管道是用于空氣運輸和分配的管道系統(tǒng)。有復合風管和無機風管兩種。復合風管以Durkct風管為代表。可按截面形狀和材料分類。
Piping is a piping system for air transportation and distribution. There are two kinds of composite air duct and inorganic air duct. Composite duct is represented by Durkct duct. It can be classified by section shape and material.
風管制作不銹鋼風管制作是在咬口、鉚釘、法蘭翻邊四個角的接縫處涂上密封膠（如中性玻璃膠）。在涂抹密封劑之前，應表面灰塵和油污。風管按截面形狀可分為圓形風管、矩形風管、扁圓形風管等。其中，圓形風管阻力小，但高度尺寸大，制造復雜。因此，應用主要以矩形風管為主。
Air duct fabrication Stainless steel air duct fabrication is to apply sealant (such as neutral glass glue) on the joints of the four corners of the seam, rivet and flange flanging. Before applying sealant, dust and oil stain on the surface shall be removed. The air duct can be divided into round air duct, rectangular air duct, flat round air duct, etc. according to the section shape. Among them, the round air duct has small resistance, but its height and size are large and its manufacturing is complex. Therefore, rectangular air duct is mainly used.
風管的優(yōu)點：
Advantages of air duct:
1．減少泄漏。螺旋風管的安裝顯著減少了管道之間的連接點，更大限度地減少了管件接頭處的泄漏。典型的螺旋風管長度為3~6m，而典型的矩形風管長度僅為1、5米。 ~1、5m。
1. Reduce leakage. The installation of spiral air duct significantly reduces the connection points between pipes, and further reduces the leakage at the pipe fitting joints. The typical spiral air duct is 3-6m long, while the typical rectangular air duct is only 1-5m long~ 1、5m。
2、標準化產品。螺旋風管配件（管件、接頭）的生產自動化程度高、系統(tǒng)化、質量控制工業(yè)化。
2. Standardized products. The production of spiral air duct fittings (pipe fittings and joints) is highly automated, systematic and industrialized in quality control.
2、安裝成本低。圓形風管系統(tǒng)的安裝時間僅為類似矩形風管的1/3、
2. Low installation cost. The installation time of circular air duct system is only 1/3 of that of similar rectangular air duct
3、只需要更小的安裝空間。在不增加任何壓降的情況下，直徑為 1 的圓形管可以在相同的安裝空間內代替矩形管。
3. Only smaller installation space is required. Under the condition of not increasing any pressure drop, the circular pipe with diameter of 1 can replace the rectangular pipe in the same installation space.
