随着工业化改革及环保的重视,人们对厂房车间里的工作环境要求逐步提高,尤其是厂房车间里的空气质量、温度高低直接影响到室内人员的身心健康和工作效率。
 
厂房通风的主要目的是通过室内外气流的流通换气来改变空气温度、提高空气品质,并在人体活动区维持一定的温度、洁净度,这不仅与通风量有关,而且在很大程度上还与室内气流流态有关。近年来,国外有关学者对通风评价方法进行了大量的研究,对通风效率进行了更为科学的定义,通风指标可以分为两个方面:一是表示换气能力;二是表示系统的排除污染物能力。而工业风扇的通风是将室内空气通过排风口、门窗吹出、产生的负压使新鲜的空气直接进入工作区,并在地板上形成一层由较凉的新鲜空气扩散。
 
工业风扇的通风是在室内形成循环气流,并与室外空气循环交换,并且能吹散湿气、加速水汽蒸发,而且避免采用冷却除湿方法所造成的送风温度过低带来的吹风感。
 
对于面积大的厂房,其新风的需要量也大大增加,若采用传统设备的集中送风,送风速度或冷气的高度可能过大,影响污染物的排出及工作区的舒适性。工业风扇采用顶部向下推送循环气流,影响范围可达1500平米以上,可避免冷却其它非人员热源又节省能耗。
 
工业风扇作为一种新型的厂房车间通风方式在国内外得到生产工厂的关注,工业风扇具有特的气流组织,能提供良好的通风降温,有效地排除室内污染物,且具有明显的节能效果。

With the industrialization reform and the emphasis on environmental protection, People's working environment requirements in the workshop have been gradually improved, especially the air quality and temperature in the workshop have a direct impact on the physical and mental health and work efficiency of indoor personnel. The main purpose of ventilation in factory building is to change the air temperature and improve the air quality through the ventilation of indoor and outdoor airflow, and to maintain a certain temperature and cleanliness in the human activity area, which is not only related to the ventilation rate, but also to a large extent with the indoor air flow pattern. In recent years, foreign scholars have done a lot of research on ventilation evaluation methods, and have defined the ventilation efficiency more scientifically. The ventilation index can be divided into two aspects: one is the ventilation capacity; Second, the ability of the system to remove pollutants. The ventilation of the industrial fan is to blow the indoor air through the air vent, doors and windows, resulting in negative pressure so that fresh air directly into the work area, and on the floor to form a layer of cooler fresh air diffusion. Industrial Fan ventilation is in the indoor air circulation, and outdoor air circulation exchange, and can blow away moisture, accelerate water vapor evaporation, and avoid cooling dehumidification method caused by the supply air temperature is too low to bring the feeling of blowing. If the traditional equipment is used for centralized air supply, the velocity of air supply or the height of air-conditioning may be too high, which will affect the discharge of pollutants and the comfort of working area. Industrial fans use top down to push the circulation air flow, the impact area can reach more than 1500 square meters, can avoid cooling other non-personnel heat source and save energy. Industrial fans, as a new type of ventilation mode in workshop, have been paid attention to by factories at home and abroad. Industrial fans have unique air distribution, can provide good ventilation and cooling, and effectively remove indoor pollutants, and has the obvious energy-saving effect.
