I believe that many users of evaporative air cooler have encountered this problem. The cooling effect is particularly good after the air cooler installed. It can be said that you are never willing to turn it off from work to get off work every day, but after using it for a period of time, You will find that its cooling effect is not good. In fact, the reasons may be various. However, some customers find that there is no abnormality in the machine, the power and water supply are normal, and the machine inspection does not find any damage to the spare parts, but it is The cooling effect is not good. When encountering this situation, it is usually because the cooling pad, the core cooling component of the environmentally friendly air conditioner, if it is clogged, resulting in the cooling pad not being fully wetted and the water evaporation area being insufficient, thus affecting the cooling effect of the air cooler. So what is going on? Let’s take a look together.

The cooling pad of air cooler usually have three types of wave heights: 5mm, 7mm and 9mm, which are often referred to as 5090, 6090 and 7090 cooling pad in our industry. In fact, the cooling pad ripples are 60°×30° staggered and opposed, 45° ×45° staggered arrangement. High-quality cooling pad are made of a new generation of polymer materials and spatial cross-linking technology. They have the advantages of high water absorption, high water resistance, anti-mildew, and long service life. Moreover, the total evaporation area is dozens or hundreds of times larger than the surface, and the water evaporation efficiency is as high as more than 90%. It does not contain surfactants, naturally absorbs water, has fast diffusion speed, and has long-lasting effectiveness. A drop of water can be completely evaporated in 4 to 5 seconds. The national standard document for evaporative refrigeration in the air cooler industry requires that the natural water absorption of the water curtain must reach 60~70mm/5min or 200mm/1.5hour. If this technical parameter cannot be reached, the water evaporation efficiency of the air cooler cooling pad will drop a lot, and the evaporation amount Not enough will not only cause the cooling effect to decrease, but also may lead to incomplete water evaporation and water blowing out of the air conditioner outlet. This will not only affect our experience of using air cooler machine, but also greatly reduce the service life of air cooler .

When we encounter this kind of water cooling pad blockage that causes the cooling effect of the evaporative cooler to be poor or continues to decline, the first thing we do is to clean and maintain the cooling pad in a timely manner.  If you want the water evaporative cooler host to keep clean, cool and odor-free for a long time To improve the air supply effect, we must do regular cleaning and maintenance services. it is recommended to clean and maintain it twice a year. If the use environment is easy to cause the water curtain to become dirty, it is best to keep it at 1- Clean once every 2 months. The frequency of cleaning can be determined based on specific usage.
