Description
技术领域technical field
本发明属于空调设备技术领域，具体涉及一种节水型填料裹管式蒸发冷却空调系统。The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a water-saving filler-wrapped tube-type evaporative cooling air-conditioning system.

如今蒸发冷却技术已经被广泛应用于各种场所，无论是在技术还是在形式上都已经趋近于成熟，但是蒸发冷却空调机组的水质处理问题却一直是人们关注和亟待改进的。由于蒸发冷却空调一直采用的是循环水，一方面导致蒸发冷却空调机组内部的填料和盘管容易结垢，减短了机组的使用寿命；另一方面要定期对水箱中的水进行排污处理，易造成水资源的浪费。Nowadays, evaporative cooling technology has been widely used in various places, both in terms of technology and form, it has been approaching maturity, but the water quality treatment of evaporative cooling air-conditioning units has always been concerned and needs to be improved urgently.

It is easy to cause waste of water resources.

However, when using tubular indirect evaporative cooling technology, due to the short contact time between water and air, it is easy to cause insufficient heat and moisture exchange between water and air. The heat effect is not good.
为了改善这一缺陷，现在已有在管内布置螺旋丝的方法，这样做的目的能有效降低空气在管内的流速，延长水与空气的接触时间；为了达到同样的效果，还可以将填料布置在卧式设置的换热管之间，增强水与空气的换热效果，提高制冷效率。In order to improve this defect, there is now a method of arranging spiral wires in the pipe, which can effectively reduce the flow rate of air in the pipe and prolong the contact time between water and air; in order to achieve the same effect, the packing can also be arranged in Between the horizontally arranged heat exchange tubes, the heat exchange effect between water and air is enhanced, and the cooling efficiency is improved.
