我要詢價詳細介紹
射流（誘導）風機的原理來自于空氣動力學中高速噴流的擾動特性，利用噴出帶有較高動能的高速氣流來誘導及擾拌周圍大量空氣，并將其帶至特定的目標方向。噴流中心速度由噴嘴出口點起逐漸減低，但是噴流寬度逐漸增加,所誘導的周圍的空氣量也逐漸增加。一方面稀釋室內(nèi)有害氣體，另一方面帶動室內(nèi)空氣流動，有害氣體集中而快速地沿著預設的空氣流道行進至排風機處，由排風機排走，從而實現(xiàn)地下車庫的良好換氣。
The principle of jet (induced) fan comes from the disturbance characteristics of high-speed jet in aerodynamics. It uses the high-speed jet with high kinetic energy to induce and disturb a large amount of surrounding air and bring it to a specific target direction. The jet center velocity decreases gradually from the nozzle outlet point, but the jet width increases gradually, and the induced surrounding air volume also increases gradually. On the one hand, the indoor harmful gas is diluted, on the other hand, the indoor air is driven to flow, and the harmful gas travels to the exhaust fan along the preset air flow channel and is discharged by the exhaust fan, so as to realize good ventilation of the underground garage.
射流(誘導)風機應用于地下車庫時，可以有效降低車庫內(nèi)有害氣體與煙霧的濃度，保持良好空氣，改善車庫環(huán)境。應用于局部污染環(huán)境時，利用高壓噴出的氣流引導周圍的大量氣體到指定的方向與區(qū)域，從而達到降低廢氣濃度，提高空氣質(zhì)量的目的。
When the jet (induced) fan is applied to the underground garage, it can effectively reduce the concentration of harmful gas and smoke in the garage, maintain good air and improve the garage environment. When applied to the local polluted environment, the high-pressure jet of air is used to guide a large amount of surrounding gas to the specified direction and area, so as to reduce the concentration of waste gas and improve air quality.
