        濟南通風管道的通風原則分為幾類?

        通風是一種換氣設備,它是用機械或自然的方法向室內空間送入足夠的新鮮空氣,同時把室內不符合衛生要求的污濁空氣排出,使室內空氣滿足衛生要求和生產過程需要,通風管道設備有著十分廣泛的使用范圍。
        Ventilation is a kind of ventilation equipment, which uses mechanical or natural methods to send enough fresh air to the indoor space, while exhausting the dirty air which does not meet the sanitary requirements, so that the indoor air can meet the sanitary requirements and the needs of the production process. The ventilation pipe equipment has a very wide range of use.
        當今,建筑中完成通風工作的各項設施,統稱通風管道設備。通風管道設備分排風扇,換氣扇,風機等,又分工業用及家用二種。而風機又分高、中、低、負壓等。
        Nowadays, the ventilation facilities in buildings are called ventilation pipe equipment. Ventilation duct equipment is divided into exhaust fan, ventilator, fan, industrial and household two kinds. And the fan is divided into high, medium, low, negative pressure and so on.

        1、稀釋通風
        1. Dilution ventilation
        稀釋通風又稱混合通風,即送人比室內污染物濃度低的空氣與室內空氣混合,以此降低室內污染物的濃度,達到衛生標難。
        Dilution ventilation, also known as mixed ventilation, is to send air with lower concentration than indoor pollutants to mix with indoor air, so as to reduce the concentration of indoor pollutants and meet the health standards.
        2、置換通風
        2. Displacement ventilation


        在置換通風系統中,新鮮冷空氣由房間底部以很低的速度送入,送風溫差僅為2—4Y。送入的新鮮空氣因密度大而像水一樣彌漫整個房間的底部,熱源引起的熱對流氣流使室內產生垂直的溫度禪度,氣流緩慢上升,脫離工作區,將余熱和污染物推向房間頂部,然后由設在頂棚上或房間頂部的排風口直接排出。
        In the displacement ventilation system, fresh cold air is fed from the bottom of the room at a very low speed, and the temperature difference of the air supply is only 2-4y. Because of the high density of the fresh air, it permeates the bottom of the room like water. The heat convection air flow caused by the heat source makes the room produce a vertical temperature Zen degree. The air flow rises slowly and leaves the working area. The waste heat and pollutants are pushed to the top of the room, and then directly discharged by the air outlet set on the ceiling or the top of the room.
        濟南通風管道廠家發現室內空氣近似活塞狀流動,使污染物隨空氣流動從房間頂部排出,工作區基本處于送入空氣中,即工作區污染物濃度約等于送人空氣的濃度,這是置換通風與傳統的稀釋全面通風的更大區別。在通風管道中,顯然置換通風的通風效果比稀釋通風要好。
        Jinan ventilation duct manufacturers found that the indoor air flow is almost piston like, which makes the pollutants discharged from the top of the room with the air flow. The working area is basically in the air, that is, the concentration of pollutants in the working area is approximately equal to the concentration of the air sent to the air, which is a greater difference between displacement ventilation and traditional dilution full face ventilation. It is obvious that displacement ventilation is better than dilution ventilation in ventilation duct.
        3、局部通風
        3. Local ventilation
        局部通風就是利用局部氣流,使局部地點不受有害物的污染,造成良好的空氣環境。
        Local ventilation is the use of local air flow, so that local sites are not polluted by harmful substances, resulting in a good air environment.
        局部通風系統分為局部送風和局部排風兩大類。局部排風是將污染物就地捕集、凈化后排放至室外。局部送風是將經過處理的、合乎要求的空氣送到局部工作地點,以保證局部區域的空氣條件。局部通風方式作為保證工作和生活環境空氣品質、防止室內環境污染的技術措施應優先考慮。
        Local ventilation system can be divided into local air supply and local exhaust. Local exhaust is to collect and purify pollutants on the spot and then discharge them to the outdoor. Local air supply is to send the treated and qualified air to the local working place to ensure the air condition in the local area. As a technical measure to ensure the air quality of working and living environment and prevent indoor environmental pollution, local ventilation should be given priority. 上一篇:山東通風管道的安裝質量該如何把控
