　　在噪聲控制要求高的情況下，應(yīng)選擇低噪聲的通風(fēng)管道設(shè)備。不同類型的通風(fēng)管道設(shè)備在風(fēng)量、風(fēng)壓相同的情況下，葉片的離心式通風(fēng)設(shè)備噪聲較小，葉片的前向版本的離心式通風(fēng)設(shè)備噪聲較大。適當(dāng)降低通風(fēng)設(shè)備的速度。通風(fēng)設(shè)備的旋轉(zhuǎn)噪聲與葉輪圓周速度的10次方成正比，渦流噪聲與葉輪圓周速度的6次方(或5次方)成正比。因此，降低速度可以降低噪音。
　　In the case of high noise control requirements, low noise ventilation pipe equipment should be selected. In the case of the same air volume and air pressure, the centrifugal ventilation equipment with different types of ventilation pipe equipment has less noise, and the forward version of the centrifugal ventilation equipment with blades has more noise. Reduce the speed of ventilation equipment properly. The rotating noise of the ventilation equipment is directly proportional to the 10th power of the peripheral speed of the impeller, and the eddy noise is directly proportional to the 6th power (or 5th power) of the peripheral speed of the impeller. Therefore, reducing the speed can reduce the noise.
　　在設(shè)計(jì)通風(fēng)系統(tǒng)時(shí)，應(yīng)盡量減少系統(tǒng)的壓力損失。當(dāng)通風(fēng)系統(tǒng)的總?cè)莘e和壓力損失較大時(shí)，可分為小系統(tǒng)。管道內(nèi)氣流速度不宜過高，以免造成再生噪聲。確定管道內(nèi)的流速應(yīng)根據(jù)不同要求，按有關(guān)規(guī)定進(jìn)行選擇。
　　When designing the ventilation system, the pressure loss of the system should be minimized. When the total volume and pressure loss of ventilation system is large, it can be divided into small systems. The air velocity in the pipeline should not be too high to avoid regeneration noise. The flow rate in the pipeline shall be determined according to different requirements and relevant regulations.
　　通風(fēng)管道是一種使空氣流通，降低有害氣體濃度的市政基礎(chǔ)設(shè)施。它也是目前工廠車間的主要冷卻方式。使用通風(fēng)管道降溫時(shí)應(yīng)注意哪些細(xì)節(jié)?
　　Ventilation pipe is a kind of municipal infrastructure which can make the air circulate and reduce the concentration of harmful gases. It is also the main cooling mode in the factory. What details should be paid attention to when using ventilation pipe to cool down?
　　，深呼吸，冷靜下來(lái)。由于建筑、機(jī)械設(shè)備、人體等熱源的影響，需要通風(fēng)的地方氣溫高于室外。負(fù)壓風(fēng)機(jī)能迅速排出室內(nèi)熱空氣，使室內(nèi)溫度與室外溫度一致，不使車間溫度升高。

　　First, take a deep breath and calm down. Due to the influence of heat sources such as buildings, mechanical equipment, human body, etc., the air temperature in the place requiring ventilation is higher than that outside. The negative pressure fan can quickly discharge the indoor hot air, so that the indoor temperature is consistent with the outdoor temperature, and the workshop temperature will not rise.
　　第二，空氣的流動(dòng)帶走了身體的熱量?？諝獾牧鲃?dòng)加速了汗水的蒸發(fā)，吸收了身體的熱量，使身體感到?jīng)鏊拖褡匀伙L(fēng)一樣涼爽。
　　Second, the flow of air takes away heat from the body. The flow of air accelerates the evaporation of sweat, absorbs the heat of the body, and makes the body feel cool, just like the natural wind.
　　第三，負(fù)壓風(fēng)機(jī)只有通風(fēng)降溫作用，沒有制冷功能，降溫是人體的感覺。說(shuō)一臺(tái)負(fù)壓風(fēng)扇能下降多少溫度是無(wú)知的。
　　Third, the negative pressure fan only has the function of ventilation and cooling, and has no cooling function. Cooling is the feeling of human body. It is ignorant to say how much temperature a negative pressure fan can reduce.
　　第四，整個(gè)通風(fēng)項(xiàng)目需要配合水幕的使用，夏季時(shí)車間溫度更高可控制在28攝氏度以內(nèi)。但人體的涼感可與空調(diào)相比，對(duì)水幕的人會(huì)感到稍長(zhǎng)一點(diǎn)的冷而無(wú)法忍受。
　　Fourth, the whole ventilation project needs to cooperate with the use of water curtain. In summer, the maximum workshop temperature can be controlled within 28 ℃. But the human body's cool feeling can be compared with that of air conditioning, and people with water curtain will feel a little longer cold and can't stand it.
