如果你想實(shí)現(xiàn)濟(jì)南通風(fēng)管道的多方面的通風(fēng)，你可以使用機(jī)械通風(fēng)或自然通風(fēng)。根據(jù)系統(tǒng)不同，綜合通風(fēng)可分為綜合送風(fēng)、綜合排風(fēng)和綜合送風(fēng)排氣三類。根據(jù)不同的制的不同，綜合通風(fēng)可分為稀釋通風(fēng)和置換通風(fēng)。那么通風(fēng)管道的機(jī)械通風(fēng)原理是什么呢？讓我們來(lái)看看通風(fēng)管道。

If you want to achieve multiple ventilation of Jinan ventilation duct, you can use mechanical ventilation or natural ventilation. According to different systems, comprehensive ventilation can be divided into three categories: comprehensive air supply, comprehensive exhaust and comprehensive air supply and exhaust. According to different systems, comprehensive ventilation can be divided into dilution ventilation and displacement ventilation. So what is the mechanical ventilation principle of ventilation duct? Let's look at the ventilation duct.

1稀釋通風(fēng)

1 Dilution ventilation

稀釋通風(fēng)又稱混合通風(fēng)，即將低于室內(nèi)污染物濃度的空氣與室內(nèi)空氣混合，降低室內(nèi)污染物濃度，達(dá)到衛(wèi)生標(biāo)準(zhǔn)。

Dilution ventilation, also known as mixed ventilation, means that the air below the concentration of indoor pollutants is mixed with indoor air to reduce the concentration of indoor pollutants and meet the health standards.

2置換通風(fēng)

2 Displacement ventilation

在更換通風(fēng)系統(tǒng)中，新鮮冷空氣以非常低的速度從房間底部輸送，送風(fēng)溫差僅為2-4Y。由于密度高，新鮮空氣像水一樣擴(kuò)散到整個(gè)房間的底部。熱源引起的熱對(duì)流氣流使室內(nèi)產(chǎn)生垂直的溫度禪，氣流緩慢上升，從工作區(qū)域分離，將余熱和污染物推到房間頂部。天花板或房間頂部的排氣口直接排出。

In the replacement ventilation system, fresh and cold air is transported from the bottom of the room at a very low speed, and the temperature difference of the air supply is only 2-4Y. Due to the high density, fresh air diffuses to the bottom of the whole room like water. The heat convection air flow caused by the heat source causes a vertical temperature rise in the room. The air flow slowly rises and separates from the working area, pushing the waste heat and pollutants to the top of the room. The exhaust from the ceiling or the top of the room is directly discharged.
ssssssss

室內(nèi)空氣幾乎像活塞一樣流動(dòng)，使污染物隨空氣流動(dòng)從房間頂部排出，工作區(qū)基本進(jìn)入空氣，即工作區(qū)污染物濃度約等于空氣濃度，是替代通風(fēng)與傳統(tǒng)稀釋綜合通風(fēng)的Z大區(qū)別。在通風(fēng)管道中，替代通風(fēng)的通風(fēng)效果明顯優(yōu)于稀釋通風(fēng)。

The indoor air flows almost like a piston, so that the pollutants are discharged from the top of the room with the air flow, and the working area basically enters the air, that is, the concentration of pollutants in the working area is about equal to the air concentration, which is the Z big difference between alternative ventilation and traditional dilution comprehensive ventilation. In the ventilation duct, the ventilation effect of alternative ventilation is obviously better than that of dilution ventilation.

3局部通風(fēng)

3 Local ventilation

局部通風(fēng)是利用局部氣流，使局部位置不受有害物質(zhì)污染，造成良好的空氣環(huán)境。

Local ventilation is the use of local air flow to prevent local locations from being polluted by harmful substances and create a good air environment.

局部通風(fēng)系統(tǒng)分為局部送風(fēng)和局部排風(fēng)兩類。局部排風(fēng)是將污染物就地收集。凈化后排放到室外。局部送風(fēng)處理。符合要求的空氣送至當(dāng)?shù)毓ぷ鲌?chǎng)所，保證當(dāng)?shù)乜諝鈼l件。當(dāng)?shù)赝L(fēng)作為保證工作和生活環(huán)境空氣質(zhì)量的一種方式應(yīng)優(yōu)先考慮防止室內(nèi)環(huán)境污染的技術(shù)措施。

The local ventilation system is divided into local air supply and local exhaust. Local exhaust is to collect pollutants on site. After purification, put it outside. Local air supply treatment. The qualified air shall be sent to the local workplace to ensure the local air conditions. As a way to ensure the air quality of the working and living environment, local ventilation should give priority to technical measures to prevent indoor environmental pollution.
