　　通風(fēng)管道工作原理

Working principle of ventilation ducts

　　通風(fēng)管道的工作原理主要基于空氣流動(dòng)的原理，通過合理設(shè)置進(jìn)風(fēng)口和排風(fēng)口，實(shí)現(xiàn)室內(nèi)外空氣的有效交換，進(jìn)而改善室內(nèi)空氣質(zhì)量，維持舒適的環(huán)境。具體來說，通風(fēng)管道系統(tǒng)可以分為自然通風(fēng)和強(qiáng)制通風(fēng)兩種。自然通風(fēng)的原理是利用氣流的重力差和氣壓差，使空氣在進(jìn)風(fēng)口和排風(fēng)口之間循環(huán)流動(dòng)，實(shí)現(xiàn)室內(nèi)空氣的新鮮和污濁空氣的排除。強(qiáng)制通風(fēng)則是通過機(jī)械設(shè)備如風(fēng)機(jī)、風(fēng)量調(diào)節(jié)器等設(shè)備的協(xié)助，增加氣流的速度和流量，強(qiáng)制性地將污濁空氣排出，同時(shí)補(bǔ)充新鮮空氣。

The working principle of ventilation ducts is mainly based on the principle of air flow. By reasonably setting the inlet and outlet, effective exchange of indoor and outdoor air is achieved, thereby improving indoor air quality and maintaining a comfortable environment. Specifically, ventilation duct systems can be divided into two types: natural ventilation and forced ventilation. The principle of natural ventilation is to use the difference in gravity and pressure of the airflow to circulate air between the inlet and outlet, achieving the elimination of fresh and polluted indoor air. Forced ventilation is achieved through the assistance of mechanical equipment such as fans, air volume regulators, etc., to increase the speed and flow of airflow, forcibly expel polluted air, and supplement fresh air.

　　管道風(fēng)機(jī)的工作原理主要是基于離心式風(fēng)機(jī)的工作原理。當(dāng)電機(jī)旋轉(zhuǎn)時(shí)，它帶動(dòng)葉輪一起旋轉(zhuǎn)。由于葉輪的形狀和旋轉(zhuǎn)速度，葉片將空氣從進(jìn)口吸入，并沿著葉片的曲線將其加速，形成高速氣流。這個(gè)高速氣流被拋出葉輪，產(chǎn)生一個(gè)負(fù)壓區(qū)域，使得周圍的空氣被吸入風(fēng)機(jī)中。當(dāng)電動(dòng)機(jī)啟動(dòng)時(shí)，葉輪開始旋轉(zhuǎn)，產(chǎn)生低壓區(qū)和高壓區(qū)。氣流由高壓區(qū)向低壓區(qū)流動(dòng)，通過管道傳輸?shù)侥繕?biāo)位置。

The working principle of pipeline fans is mainly based on the working principle of centrifugal fans. When the motor rotates, it drives the impeller to rotate together. Due to the shape and rotational speed of the impeller, the blades draw air in from the inlet and accelerate it along the curve of the blades, forming a high-speed airflow. This high-speed airflow is thrown out of the impeller, creating a negative pressure area, causing the surrounding air to be sucked into the fan. When the motor starts, the impeller begins to rotate, creating a low-pressure and high-pressure zone. The airflow flows from the high-pressure zone to the low-pressure zone and is transmitted to the target location through pipelines.

　　消防排煙管道的工作原理是通過排煙風(fēng)機(jī)將污濁空氣從室內(nèi)吸入管道，然后將其排放建筑物外部。在火災(zāi)發(fā)生時(shí)，由于高溫和濃煙的存在，煙道的一端會(huì)打開，煙霧開始從通風(fēng)管道外部排出，并將室內(nèi)的空氣排放室外。

The working principle of the fire smoke exhaust duct is to draw polluted air from the indoor area into the duct through the smoke exhaust fan, and then discharge it to the outside of the building. When a fire occurs, due to the presence of high temperature and thick smoke, one end of the flue will open, and smoke will start to be discharged from the outside of the ventilation duct, releasing indoor air to the outside.
