Can the spray fan cool down? The conclusion is affirmative. Compared with traditional air conditioners and air coolers, spray fans have lower power consumption, more energy saving, longer service life, lower failure probability, simpler and more convenient maintenance, and better humidification and cooling effects. Spray fans are generally divided into centrifugal spray fans and high-pressure nozzle spray fans: 1. Centrifugal spray fans The principle of centrifugal spray fans is that water passes through the rotating disc and the fog particle spraying device, and tiny fog droplets are scattered around by centrifugal force. Coupled with the strong wind power of the fan, the fog droplets spread faster and farther, which can reduce the temperature, purify the surrounding air and increase the humidity of indoor air. 2. High-pressure nozzle spray fan The principle of high-pressure nozzle spray fan is that after water passes through a high-pressure water pump and is subjected to a pressure of tens of kilograms, the high-pressure nozzle will generate fog, and then under the action of strong wind, the effects of cooling and dust removal can be realized, and the humidity of indoor air can also be increased.
