The progress of ventilation pipe materials is an important aspect of the progress of science and technology. The progress of the material has a direct impact on the progress of the operation mode and the stability of the quality of the product directly. This law should also be followed for the ventilation duct that we purify air conditioning.

　　從冷化空調產業(yè)初始發(fā)展到現在近三十年了，凈化空調用的通風管道還基本上停留在原材料原工藝的基礎上，這不能不算是一種遺憾。在鋼鋅鋼板風管的制作方面，大的公司使用機械化生產已不成問題（咬口條縫的氣密性還另當別論），但保溫工序如此的煩瑣、安裝工人如此的勞累，且質量不易保證的現狀依舊沒能解決。近年來，一種新的保溫材料一橡塑材料的出現，減輕了工人的勞動強度，可還是沒能擺脫其落后的勞動方式，況且這種材料目前較貴，還不能普遍使用。

　　From the initial development of the cold air conditioning industry to the recent thirty years, the ventilation pipes used for purifying the air conditioners basically remain on the basis of raw materials, which is a pity. In the steel making zinc steel sheet air pipe, production using large machinery company has no problem (airtight joint bite tongue is another matter), but the process cumbersome, so the insulation installation workers so tired, and not easy to guarantee the quality of the status quo is still not able to solve. In recent years, a new thermal insulation material, the appearance of rubber and plastic material, has lightened the labor intensity of workers, but still can not get rid of its backward labor way. Moreover, the material is expensive at present, and it can not be widely used.

　　在一般空調中，玻纖風管、玻璃鋼風管及進口的一些復合風管得到了應用，應該說復合材料風管的出現在通風管道產業(yè)中是一種進步。當然，這幾種材料的形式、性質及加工工藝都不太適合凈化工程的要求。因此在凈化工程中沒能發(fā)展，但無論如何，復合材料的出現在風管產業(yè)中是一種進步，是一種發(fā)展，復合材料是世界范圍內的一種趨勢，也可以說是工業(yè)進步的必然！

　　In general air conditioners, fiberglass air pipes, FRP pipes and some imported composite air pipes have been applied. It should be said that the emergence of composite air pipes is an improvement in the ventilation and pipe industry. Of course, the forms, properties and processing techniques of these materials are not very suitable for the requirements of the purification engineering. Therefore, it has not been able to develop in the purification engineering, but in any case, the emergence of composite materials is a progress in the wind pipe industry, and it is a development. Composite material is a trend in the world, which is also the necessity of industrial progress.

　　因此，空調的通風管道也應該使用復合材料。

　　Therefore, the ventilation duct of the environmental air conditioning should also use the composite material.
