降温原理：
Cooling Principle:
1、换气降温，由于阳光照射建筑物，机器等导致需要通风场所气温明显高于室外，通风管道设备能够把室内的热气排出，让室温和外界的温度保持平稳，不至于车间内的温度升高。
1. Ventilation cooling, because of the sunshine on buildings, machines and other causes the need for ventilation place temperature is significantly higher than the outdoor, ventilation pipeline equipment can discharge the indoor heat, so that the room temperature and the outside temperature remain stable, not to increase the temperature in the workshop.
2、空气流动带走热量，空气流动是可以吸收人体的热量，让人们感觉到凉爽。
2. Air flow takes away heat. Air flow can absorb heat from human body and make people feel cool.
3、通风管道设备只有通风降温作用，但是没有制冷功能，并且通风管道设备降温多少是没有办法知道的。
3. Ventilation pipeline equipment only has the function of ventilation and cooling, but it has no refrigeration function, and there is no way to know how much the cooling of ventilation pipeline equipment is.
4、和水帘配合使用，夏季炎热的时候可以把车间里的温度控制在28度，但人体的凉爽感觉可与空调相比，稍长时间对着水帘的人会感觉冷而受不了。
4. With water curtain, the temperature in the workshop can be controlled at 28 degrees in hot summer, but the human body's cool feeling can be compared with air-conditioning, and people facing the water curtain for a long time will feel cold and unbearable.
