負壓風機是一種新式綠色環保的通風廠房降溫，它每一個發電機組排量非常大。風量大代表著離心風機具備較大的通風工作能力。因為讓我們更強的認識該設施，今天將詳解其功效，簡單總結下負壓風機的作用是什么！

　　1、作排風通氣用：組裝在車間對話框外，一般挑選下風口、向外排風，抽出來臭味汽體，一般化工企業等運用較多。

　　2、相互配合降溫水簾應用：作為車間減溫炎熱夏季，無論車間有多熱，負壓風機系統軟件都可以讓其車間的溫度降到30C上下，并且有一定的環境濕度。

　　3、大型廠房的工業廠房宜選用風大量離心風機通風。離心風機具備容積極大、風管超大型、風扇葉片孔徑超大型、風量超大型、耗能極低、轉速比低、噪音低等特性，負壓風機從構造和材料上還分成鍍鋅鋼板正方形離心風機和玻纖音響喇叭負壓風機。

　　以上是負壓風機一部分功效，它還可以當排風扇，不論是放在地上或是掛在半空中。還能將房間內熱流快速排出來，讓常溫和外部溫度差不多，不會車間內溫度上升，期待今天專業知識你能夠非常好的把握。

　　一般組裝負壓風機的情況下，風機安裝在一側，進風口組裝在此外一側，這樣就能夠產生對流風，持續循環系統。

　　通風基本原理：

　　負壓風機運行向外排出來空氣，使房間內空氣的壓力降低，從而空氣越來越較稀，在車間內形成了一個負壓力區。以后由于標準氣壓賠償，外邊的空氣便會根據進風口進到加工廠的負壓力區，進而填補進到一個新的空氣，那樣一邊吸進一邊排出來，就形成了熱對流。

　　通氣減溫：

　　一、因為太陽光照射房屋建筑、機械設備、人體等熱原造成必須通風的地方溫度高過戶外。負壓風機能將房間內熱流快速排出來，讓常溫和外部溫度差不多，不會車間內溫度上升。

　　二、空氣流動性帶去人體發熱量，空氣流動性加快汗水揮發而消化吸收人體發熱量，進而讓人體覺得清涼，和吹風一樣清涼。

　　三、負壓風機僅有通風減溫的功效，并沒有致冷的作用，清涼是人體的覺得。負壓風機可降是多少溫度的說法是愚昧的。

　　四、和降溫水簾相互配合應用，在夏天*悶熱的過程中可將車間內溫度操縱在28℃之內。但人體的清涼覺得可與中央空調對比，稍長期沖著降溫水簾的人會感覺冷而承受不住。

　　Negative pressure fan is a new type of green and environment-friendly ventilation plant for cooling. The displacement of each generator unit is very large. Large air volume means that the centrifugal fan has greater ventilation capacity. Because it gives us a better understanding of the facility, today we will explain its efficacy in detail and briefly summarize the role of the negative pressure fan!

　　1. It is used for exhaust and ventilation: it is assembled outside the workshop dialog box. Generally, the lower tuyere is selected for external exhaust to extract the odor vapor. It is widely used in general chemical enterprises.

　　2. Application of mutual cooling water curtain: as a workshop desuperheating in hot summer, no matter how hot the workshop is, the negative pressure fan system software can reduce the temperature of the workshop to about 30C and have a certain environmental humidity.

　　3. A large number of centrifugal fans should be used for ventilation in industrial plants of large plants. The centrifugal fan has the characteristics of huge volume, super large air duct, super large fan blade aperture, super large air volume, extremely low energy consumption, low speed ratio and low noise. The negative pressure fan is also divided into galvanized steel plate square centrifugal fan and glass fiber acoustic horn negative pressure fan in terms of structure and materials.

　　These are part of the functions of the negative pressure fan. It can also be used as an exhaust fan, whether on the ground or in mid air. It can also quickly discharge the heat flow in the room, so that the normal temperature is almost the same as the external temperature, and the temperature in the workshop will not rise. I hope you can grasp the professional knowledge today.

　　Generally, when the negative pressure fan is assembled, the fan is installed on one side and the air inlet is assembled on the other side, so that the convection wind can be generated and the continuous circulation system can be realized.

　　Basic principle of ventilation:

　　The negative pressure fan exhausts air outward during operation, which reduces the air pressure in the room, so that the air becomes thinner and thinner, forming a negative pressure zone in the workshop. In the future, due to the standard air pressure compensation, the outside air will enter the negative pressure area of the processing plant according to the air inlet, and then fill in a new air, which will be sucked in and discharged at the same time, forming thermal convection.

　　Ventilation desuperheating:

　　1、 Because the sunlight irradiates the building, mechanical equipment, human body and other pyrogens, the temperature in the places that must be ventilated is higher than that in the outdoors. The negative pressure fan can quickly discharge the heat flow in the room, so that the normal temperature is almost the same as the external temperature, and the temperature in the workshop will not rise.

　　2、 Air mobility takes away the heat of the human body. Air mobility accelerates the evaporation of sweat and digests and absorbs the heat of the human body, which makes the human body feel as cool as the wind.

　　3、 Negative pressure fan only has effect of the ventilation and temperature reduction, and has no effect of the cooling. Cooling is feeling of the human body. It is foolish to say how much temperature the negative pressure fan can drop.

　　4、 With the cooling water curtain, the temperature in the workshop can be controlled within 28 ℃ in the hottest summer. However, the coolness of the human body can be compared with that of the central air conditioner. People who rush the cooling water curtain for a long time will feel cold and can't bear it.
