局部送風主要用于局部降溫，又分為系統式和分散式兩種。下面來給大家詳細介紹一下通風管道局部送風的工作方式：
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.系統式送風系統系統式就是通風設備將室外空氣送至工作地點。空氣經集中處理后送入局部工作區。分散式局部送風一般使用軸流風扇或噴霧風扇，采用室內再循環空氣。
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.分散式送風系統分散式借助軸流風扇或噴霧風扇，直接將室內空氣吹向作業地帶進行循環通風。
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)風扇送風在作業點附近設置普通軸流風機進行循環吹風，加快對流散熱。工作點風速要求：①輕作業——2～4m/s;②中作業——3～5m/s;③重作業——5～7m/s。適用于氣溫不大于35℃，且非產塵的車間。
(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)噴霧風扇送風噴霧風扇是在通風機上裝有噴霧裝置的局部送風設備，即在普通軸流風機上加設甩水盤構成噴霧風扇送風具有降溫作用。
(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.
霧灑落在人體表面又能促進人體蒸發散熱，懸浮在空氣中的小霧滴還能吸收熱輻射，減輕人體受熱輻射的影響。
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.
但也會引起人造汗。要求：要求噴霧風扇應有足夠的風量、噴霧量和射程;噴霧的水滴<60μm，大不超過100μm。風速不大于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.
