Application

The cooling of wet curtain fan is to use the principle of water evaporation and cooling, coupled with related equipment for ventilation to achieve cooling purposes. Although this method is cheaper than air conditioning, it also needs to be equipped with corresponding equipment. Microfog cooling is to spray water into greenhouse in the form of micron or 10 micron fog particles, which can evaporate rapidly. It can absorb a large amount of heat in the air by utilizing the large latent heat of water evaporation, and then discharge moist air outdoors to achieve the purpose of cooling.

Advantage
