1、机械通风特点靠风机动力使空气流动的方法称为机械通风。进风和排风可进行处理, 通风参数可根据要求选择确定, 可确保通风效果, 但通风管道复杂, 投资费和运行管理费用大。
1, the mechanical ventilation characteristics of the air driven by the wind power to move the air is called mechanical ventilation. The air inlet and exhaust air can be treated. The ventilation parameters can be selected according to the requirements, and the ventilation effect can be ensured. However, the ventilation pipe is complicated, and the cost of investment and operation management is large.
2、自然通风特点依靠室外空气温差所造成的热压, 或利用室外风力作用在建筑物上所形成的压差, 使室内外的空气进行交换, 从而改善室内的空气环境。不需动力, 经济; 但进风不能预处理, 排风不能净化, 污染周围环境; 且通风效果不稳定。
2, the characteristics of natural ventilation depend on the hot pressure caused by outdoor air temperature difference, or the pressure difference formed on the building by the effect of outdoor wind, so that the air inside and outside the room is exchanged to improve the indoor air environment. No need for power and economy, but air intake can not be pretreated, exhaust air can not be purified, pollute the surrounding environment, and the ventilation effect is not stable.

3、局部通风局部通风就是在有害物产生的地点直接把它们捕集起来,经过净化处理排至室外.局部通风管道所需要的风量小,效果好,设计时应优先考 虑。分为:局部排风和局部送风① 局部排风:在集中产生有害物的局部地点, 设置捕集装置, 将有害物排走, 以控制有害物向室内扩散。这是防毒, 排尘有效的通风方法。②局部送风:向局部工作地点送风, 使局部地带造成良好的空气环境。主要用于局部降温.又分为系统式和分散式。系统式就是通风管道将室外空气送至工作地点。分散式借助轴流风扇或喷雾风扇, 直接将室内空气吹向作业地带进行循环通风。
3. Local ventilation in local ventilation is to capture them directly in the place where harmful things are produced and to be discharged to the outdoor after purification. The air volume required for the local ventilation pipe is small, the effect is good, and the design should be given priority. It is divided into local exhaust and local air supply (1) local exhaust. In the local place where harmful objects are concentrated, trap sets are set up to remove harmful substances to control the diffusion of harmful substances into the room. This is an effective ventilation method for antivirus and dust removal. (2) local air supply: air supply to local workplaces, causing a good air environment in some areas. It is mainly used for local cooling. It is also divided into system type and dispersive type. The system is the ventilation pipe to send outdoor air to the workplace. With the help of axial fan or spray fan, the indoor air is blown directly to the working area to circulate ventilation.
4、全面通风:就是对房间进行通风换气, 以稀释室内有害物, 消除余热, 余温, 使之符合卫生标准要求。全面通风的动力可以是自然风压和热压, 也可以是风机风压。
4, comprehensive ventilation: that is to ventilate the room to dilute indoor harmful substances, eliminate residual heat and keep the temperature to meet the hygienic standard requirements. The power of full ventilation can be natural wind pressure and hot pressure, or wind pressure of fans.
5、全面通风具体实施方法又可分为全面排风法, 全面送风法, 全面排送风法和全面送、局部排风混合法等, 可根据车间的实际情况采用不同的方法。
5. The concrete implementation method of comprehensive ventilation can be divided into comprehensive ventilation method, comprehensive ventilation method, comprehensive ventilation method, comprehensive delivery and local exhaust mixing method, and different methods can be adopted according to the actual situation of the workshop.
