通风管道是一种使空气流通，降低有害气体浓度的市政基础设施，也是目前工厂车间主流的降温方式，那么利用通风管道降温需要注意哪些细节呢?小编根据长期的工程经验发现以下必须要注意的四点：
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:

一，换气降温。由于阳光照射建筑物、机器设备、人体等热源导致需要通风的场所气温高于室外。负压风机能将室内热气迅速排出，让室温和外界温度持平，不至于车间内温度升高。
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，空气流动带走人体热量，空气流动加速汗液蒸发而吸收人体热量，从而让人体感觉凉爽，和自然风一样凉爽。
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，负压风机只有通风降温的作用，没有制冷的功能，凉爽是人体的感觉。负压风机能降多少温度的说法是无知的。
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.
四点，整个通风工程需要和水帘配合使用，在夏季更炎热的时候可将车间内温度控制在28摄氏度以内。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：如何将酒店厨房油烟排干净?
