通風麻豆视频官网是通風和空氣調節體係的主要組成有些，它把通風、空調體係的進風口，空氣的熱、濕及淨化處理設備，送(排)風口、部件和風機連變成一個全體，使之有用運轉。下麵來針對濟南通風麻豆视频官网加工的相關知識進行介紹。

Ventilation ducts are the main components of the ventilation and air conditioning system. They connect the air inlets of the ventilation and air conditioning system, the heat, humidity and purification treatment equipment of the air, the air supply (exhaust) outlets, components and fans into a whole to make them work effectively. Next, we will introduce the relevant knowledge of Jinan ventilation pipe processing.

通風麻豆视频官网的規劃使命，便是要合理地安排空氣活動，在確保運用作用的前提下，使工程初投資和運轉維護費用省。因而，通風麻豆视频官网規劃是不是合理，直接影響到全部通風、空氣調節工程締造和運用的技能經濟作用.由此可見，統籌思考通風麻豆视频官网規劃中的各種疑問足十分主要的。

The planning mission of the ventilation duct is to reasonably arrange air activities, and save the initial investment and operation and maintenance costs of the project on the premise of ensuring the use role. Therefore, whether the ventilation duct planning is reasonable or not directly affects the technical and economic effects of the creation and application of all ventilation and air conditioning projects. It can be seen that it is very important to comprehensively consider various questions in the ventilation duct planning.

風管內空氣活動的阻力

Resistance of air movement in air duct

空氣沿風管活動的阻力有兩種，一種是因為空氣自身的粘滯性及其和管壁之間的衝突而發生的沿程能量丟失，稱為衝突阻力或沿程阻力;另一種是空氣在流經風管中的管件和設備時，因為流速的巨細或方向改變及隨之發生的渦流形成對比集中的能量丟失，稱為有些阻力。

There are two kinds of resistance of air movement along the air duct. One is the energy loss along the air due to the viscosity of the air itself and the conflict between the air and the pipe wall, which is called the conflict resistance or the resistance along the air duct; The other is that when the air flows through the pipe fittings and equipment in the air duct, the energy loss is relatively concentrated due to the change of the flow velocity or direction and the subsequent vortex, which is called some resistance.

依據流體力學原理，空氣沿任何斷麵不變的直管活動時，衝突阻力可按下式核算：

According to the principle of fluid mechanics, when the air moves along the straight pipe with any section unchanged, the conflict resistance can be calculated according to the following formula:

衝突阻力係數入與風管內空氣的活動狀況和管壁的粗糙度有關.在通風和空調體係中，薄鋼板風管的空氣活動狀況大多歸於紊流潤滑區到粗糙區之間的過渡區.通常，即便高速風管的活動狀況也處於過渡區.隻需風管直徑很小，外表粗糙的磚，混凝土風管內的活動狀況才歸於粗糙區。

The conflict resistance coefficient is related to the air movement in the duct and the roughness of the duct wall In the ventilation and air conditioning system, the air activity of the thin steel duct is mostly attributed to the transition zone between the turbulent lubrication zone and the rough zone. Generally, even the activity of the high-speed duct is in the transition zone Only the bricks and concrete air ducts with small diameter and rough appearance can be classified as rough areas.
