The circulating water pump in the machine continuously pumps the water out of the water tank and sprays it evenly on the evaporation filter through the water distribution system. When the hot air enters the special honeycomb hair net covered with cooling, the cooling water is transformed from liquid into gaseous molecules. Absorb a large amount of energy in the air. When the outdoor air is inhaled through the evaporation net, the dust and odor in the air are brought into the water tank. After the automatic filtration system, the clean, cool, oxygen-enriched air is sent into the room, and the indoor air is continuously circulated to force the indoor air. Fully convection, exhaust the turbid air with odor and high dust temperature indoors to the outside.
