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，也是目前工廠車(chē)間主流的降溫方式，那么利用通風(fēng)管道降溫需要注意哪些細(xì)節(jié)呢?小編根據(jù)長(zhǎng)期的工程經(jīng)驗(yàn)發(fā)現(xiàn)以下必須要注意的四點(diǎn)：
Ventilation pipe is a kind of municipal infrastructure which can make the air circulate and reduce the concentration of harmful gas. It is also the mainstream cooling method in factories and workshops at present. What details should be paid attention to when using the ventilation pipe to cool down? According to the long-term engineering experience, the editor has found the following four points that must be paid attention to:
濟(jì)南通風(fēng)管道
Jinan ventilation duct
一，換氣降溫。由于陽(yáng)光照射建筑物、機(jī)器設(shè)備、人體等熱源導(dǎo)致需要通風(fēng)的場(chǎng)所氣溫高于室外。負(fù)壓風(fēng)機(jī)能將室內(nèi)熱氣迅速排出，讓室溫和外界溫度持平，不至于車(chē)間內(nèi)溫度升高。
1、 Ventilation and cooling. Due to the sunlight shining on buildings, machinery and equipment, human body and other heat sources, the temperature in the places requiring ventilation is higher than that outside. The negative pressure fan can quickly exhaust the hot air in the room, keep the room temperature and the outside temperature level, and prevent the temperature rise in the workshop.
二，空氣流動(dòng)帶走人體熱量，空氣流動(dòng)加速汗液蒸發(fā)而吸收人體熱量，從而讓人體感覺(jué)涼爽，和自然風(fēng)一樣涼爽。
2、 Air flow takes away heat from the human body. Air flow accelerates the evaporation of sweat to absorb human heat, thus making the human body feel cool, as cool as the natural wind.
三，負(fù)壓風(fēng)機(jī)只有通風(fēng)降溫的作用，沒(méi)有制冷的功能，涼爽是人體的感覺(jué)。負(fù)壓風(fēng)機(jī)能降多少溫度的說(shuō)法是無(wú)知的。
3、 The negative pressure fan only has the function of ventilation and cooling, and has no refrigeration function. It is the feeling of human body to be cool. It is ignorant to say how much temperature the negative pressure fan can drop.
四點(diǎn)，整個(gè)通風(fēng)工程需要和水簾配合使用，在夏季更炎熱的時(shí)候可將車(chē)間內(nèi)溫度控制在28攝氏度以?xún)?nèi)。但人
At four o'clock, the whole ventilation project needs to be used together with water curtain, and the temperature in the workshop can be controlled within 28 ℃ in the hottest summer. But people 上一篇：如何將酒店廚房油煙排干凈?
