局部送风主要用于局部降温，又分为系统式和分散式两种。下面来给大家详细介绍一下通风管道局部送风的工作方式：
Local air supply is mainly used for local cooling, and divided into two types: system type and distributed type. Here to give you a detailed description of ventilation ducts, local air supply mode of work:
1.系统式送风系统系统式就是通风设备将室外空气送工作地点。空气经集中处理后送入局部工作区。分散式局部送风一般使用轴流风扇或喷雾风扇，采用室内再循环空气。
1., the system type air supply system is ventilation equipment, the outdoor air to the workplace. After concentrated treatment, the air is sent into the local work area. Distributed partial air supply usually uses axial flow fan or spray fan, and indoor recirculation air is adopted.
2.分散式送风系统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。
2., the distributed air distribution system, with the aid of axial fan or spray fan, directly ventilated indoor air to the work area for cyclic ventilation.
(1)风扇送风在作业点附近设置普通轴流风机进行循环吹风，加快对流散热。工作点风速要求：①轻作业——2～4m/s;②中作业——3～5m/s;③重作业——5～7m/s。适用于气温不大于35℃，且非产尘的车间。
(1) fan supply air, set up ordinary axial fan in the vicinity of operation point, carry out circulation blowing, accelerate convection heat dissipation. Working point wind speed requirements: (1) light operation - 2 ~ 4m/s; secondary operation - 3 ~ 5m/s; heavy operation - 5 ~ 7m/s. It is suitable for workshops where the temperature is not more than 35 DEG C and the dust is not produced.
(2)喷雾风扇送风喷雾风扇是在通风机上装有喷雾装置的局部送风设备，即在普通轴流风机上加设甩水盘构成喷雾风扇送风具有降温作用。
(2) the spray fan is a local air supply device equipped with an atomizing device on the fan. The fan is equipped with a water rejection disc on the common axial fan to cool the air.
雾洒落在人体表面又能促进人体蒸发散热，悬浮在空气中的小雾滴还能吸收热辐射，减轻人体受热辐射的影响。
Fog on the surface of the human body, but also to promote the human body evaporation, heat dissipation, suspended in the air of small droplets, but also to absorb heat radiation, reducing the impact of human radiation.
但也会引起人造汗。要求：要求喷雾风扇应有足够的风量、喷雾量和射程;喷雾的水滴<60μm，大不超过100μm。风速不大于3～5m/s。
But it can also cause artificial sweat. Requirements: spray fans should have sufficient air flow, spray volume and range; spray droplets <60 mu m, maximum not more than 100 mu m. Wind speed is not greater than 3 to 5m/s.
