为了实现济南通风管道的整体通风，可以采用机械通风和自然通风，根据作用机理的不同，全通风可分为稀释通风和置换通风；根据系统的不同特点，综合通风可分为三类：综合送风、综合排风和综合供排风。那你知道机械通风方式有哪些吗？接下来，济南通风管道加工厂家将在下文为大家简要介绍一下，希望能帮到大家。
In order to realize the overall ventilation of Jinan ventilation pipeline, mechanical ventilation and natural ventilation can be used. According to different action mechanisms, total ventilation can be divided into dilution ventilation and displacement ventilation; according to different characteristics of the system, comprehensive ventilation can be divided into three categories: comprehensive air supply, comprehensive exhaust and comprehensive supply and exhaust. Do you know what mechanical ventilation methods are? Next, Jinan ventilation pipe processing factory will be briefly introduced in the following, hoping to help you.
1、置换通风
1. Displacement ventilation
置换通风系统中，新鲜冷空气以ji低的速度从房间底部排出，送风温差仅为2-4y，房间内的新鲜空气由于密度高而像水一样在房间底部扩散。
In the displacement ventilation system, fresh cold air is discharged from the bottom of the room at a low speed of Ji, and the temperature difference of the air supply is only 2-4y. The fresh air in the room diffuses at the bottom of the room like water due to its high density.
热源引起的热对流使房间产生一个垂直的温度禅定度。气流缓慢上升，离开工作区域，将余热和污染物推到房间顶部，然后由天花板上的出风口或房间顶部直接排放。
The heat convection caused by the heat source makes the room produce a vertical temperature Zen degree. The air flow rises slowly, leaving the work area, pushing the waste heat and pollutants to the top of the room, and then directly discharging through the air outlet on the ceiling or the top of the room.

室内空气像活塞一样流动，污染物随气流从房间顶部排出，工作区基本上是空的。也就是说，工作区的污染物浓度与空气中的污染物浓度大致相同。济南通风管道加工厂家表示置换通气与传统的稀释通气有较大的区别。置换通气的通气效果明显优于稀释通气。
Indoor air flows like a piston, pollutants are discharged from the top of the room with the airflow, and the working area is basically empty. In other words, the concentration of pollutants in the work area is roughly the same as that in the air. Jinan ventilation pipe manufacturers said that displacement ventilation and traditional dilution ventilation have a big difference. The ventilation effect of displacement ventilation was better than that of dilution ventilation.
2、局部通风
2. Local ventilation
局部通风是利用局部气流，使局部地区不受有害物质污染，产生良好的空气环境，局部通风系统分为局部送风和局部排风，局部排放是将污染物就地收集净化后排放到室外。
Local ventilation is the use of local air flow, so that local areas are not polluted by harmful substances and produce a good air environment. Local ventilation system is divided into local air supply and local exhaust. Local emission is to collect and purify pollutants on the spot and then put them outdoors.
局部送风是将经处理合格的空气送至当地工作场所，保证当地的空气条件。局部通风作为保证工作和生活环境空气质量，防止室内环境污染的技术措施应优先考虑。
Local air supply is to send qualified air to the local workplace to ensure the local air conditions. 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.

3、稀释通风
3. Dilution ventilation
稀释通风又称混合通风，是指送人将低于室内污染物浓度的空气与室内空气混合，从而降低难以达到卫生标准的室内污染物浓度。
Dilution ventilation, also known as mixed ventilation, refers to sending people to mix the air below the indoor pollutant concentration with the indoor air, so as to reduce the indoor pollutant concentration which is difficult to reach the hygienic standard.
