I believe that everyone has been to the sea, but also blows the sea breeze, when the sea breeze blows, we will feel cool, this is actually the evaporation of the sea water to take away the heat in the air, become cooler. And the same is true of the working principle of the fan, which is to use the physical phenomenon of water evaporation to absorb heat for refrigeration.

First use the water circulator to circulate the water in the water tank to the evaporation filter, and then use the fan to suck the evaporation net into the indoor air, so that the water absorbs the heat in the air in the process of evaporation, so that the wind blown out is a cool breeze. Therefore, the main structure of the cooling fan is the evaporation filter, fan, water circulation system and electrical control part that can control the air volume.

The working principle of air conditioning cooling fan, unlike traditional air conditioning, there is no high-power equipment such as a compressor, and the main power consumption equipment is the fan, so its power consumption is almost the same as that of ordinary electric fans. And added evaporative refrigeration this technology, and better than ordinary electric fans cooling. It does not need to be fixed in one position like an air conditioner, it does not have an outdoor unit, and the bottom is equipped with rollers, which can be moved anywhere in the home, making it more convenient to use. And it has a simple structure, the technical requirements are not too high, its price is much cheaper than air conditioning, and the fan can almost be reconciled. And this kind of low power consumption, better than fan cooling, movable, cheaper price, is also its biggest advantage. That year was also the selling point of many manufacturers' promotion, and now with the development of science and technology, a lot of intelligent electronic control functions have also been added, which is more mysterious.
