部分送風(fēng)向部分作業(yè)地址送風(fēng)，使部分地帶形成良好的空氣環(huán)境。關(guān)于面積很大，操作人員較少的出產(chǎn)車間，用通風(fēng)的辦法改進(jìn)整個(gè)車間的空氣環(huán)境，既困難又不經(jīng)濟(jì)，同時(shí)也是不必要的。

Part of the air supply direction and part of the work address air supply, so that part of the formation of a good air environment. It is not only difficult but also inexpensive to improve the air environment of a workshop with a large area and fewer operators by means of comprehensive ventilation.

例如某些高溫車間，沒有必要對(duì)整個(gè)車間進(jìn)行降溫，只需向單個(gè)的部分作業(yè)地址送風(fēng)，在部分地址形成良好的空氣環(huán)境，這種通風(fēng)辦法稱為部分送風(fēng)。

For example, in some high-temperature workshops, there is no need to cool the whole workshop, only to supply air to a single part of the work address, forming a good air environment in some locations. This ventilation method is called partial air supply.

部分送風(fēng)主要用于部分降溫，又分為體系式和渙散式兩種。下面小編來給我們具體介紹一下通風(fēng)管道部分送風(fēng)的作業(yè)辦法

Partial air supply is mainly used for partial cooling, which can be divided into two types: system type and scattered type. Below is a small series to give us a specific introduction to the ventilation duct part of the air supply method of operation.

1.體系式送風(fēng)體系體系式就是通風(fēng)設(shè)備將室外空氣送作業(yè)地址。空氣經(jīng)集中處理后送入部分作業(yè)區(qū)。渙散式部分送風(fēng)一般運(yùn)用軸流電扇或噴霧電扇，選用室內(nèi)再循環(huán)空氣。

1. Systematic air supply system is that ventilation equipment delivers outdoor air to the working address. After centralized treatment, the air is sent to some working areas. Slack type partial air supply usually uses axial fan or spray fan to select indoor recirculating air.

2.渙散式送風(fēng)體系渙散式憑借軸流電扇或噴霧電扇，直接將室內(nèi)空氣吹向作業(yè)地帶進(jìn)行循環(huán)通風(fēng)。

2. the slack air supply system is slack type, which uses axial fan or spray fan to directly blow indoor air into the working area to circulate ventilation.

(1)電扇送風(fēng)在作業(yè)點(diǎn)附近設(shè)置一般軸流風(fēng)機(jī)進(jìn)行循環(huán)吹風(fēng)，加速對(duì)流散熱。作業(yè)點(diǎn)風(fēng)速要求：①輕作業(yè)——2～4m/s;②中作業(yè)——3～5m/s;③重作業(yè)——5～7m/s。適用于氣溫不大于35℃，且非產(chǎn)塵的車間。

(1) A general axial-flow fan is installed near the operating point for circulating air to accelerate convective heat dissipation. The requirements of wind speed at work points are as follows: 1) light work - 2-4m/s; 2) medium work - 3-5m/s; and 3) heavy work - 5-7m/s. Suitable for workshop with temperature not more than 35 C and non-dust production.

(2)噴霧電扇送風(fēng)噴霧電扇是在通風(fēng)機(jī)上裝有噴霧裝置的部分送風(fēng)設(shè)備，即在一般軸流風(fēng)機(jī)上加設(shè)甩水盤構(gòu)成噴霧電扇送風(fēng)具有降溫作用，霧灑落在人體表面又能促進(jìn)人體蒸發(fā)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。

(2) spray fan spray fan is part of the air supply equipment equipped with spray device on the fan, that is, add a water throwing plate on the general axial fan, and the spray fan has the cooling effect. The fog falls on the surface of the human body and promotes the evaporation and heat dissipation of the human body. The small droplets suspended in the air can absorb heat radiation and reduce the influence of the body's heating radiation.

但也會(huì)引起人工汗。要求：要求噴霧電扇應(yīng)有滿足的風(fēng)量、噴霧量和射程;噴霧的水滴<60μm，較大不超越100μm。風(fēng)速不大于3～5m/s。

But it can also cause artificial sweat. Requirements: spray fans should be satisfied with the air volume, spray volume and range; the spray droplet is <60 and m, and the maximum does not exceed 100 m. The wind speed is not more than 3-5 m/s.

通風(fēng)管道部分送風(fēng)主要應(yīng)用在：噴霧電扇適用于高溫、強(qiáng)熱輻射的作業(yè)地址。用于溫度高于35℃，輻射強(qiáng)度大于1400W/m2，細(xì)微霧滴對(duì)出產(chǎn)工藝無影響的中、重作業(yè)點(diǎn)。

The partial ventilation of ventilation pipes is mainly applied to: the spray fans are suitable for high temperature and strong heat radiation. It is used at medium and heavy operation points where the temperature is higher than 35 C and the radiation intensity is greater than 1400W/m2, and the fine mist droplets have no effect on the production process.
