Cooling fan (evaporative air conditioners) cooling principle is: when the fan operation into the
lumen produce negative pressure, and make a cake layer air through the porous wet surface
wet curtain shade of dry air force a ball temperatures drop to close to the air ShiQiuWenDu
cake layer, namely the cooling fan export dry ball than outdoor temperature dry ball low
temperature 5-12℃(dry heat area up to 15℃).the dry hot air, the temperature difference is
larger and the cooling effect of the more good. Due to the introduction of indoor air from outside
always. (by this time is called the pressure system) so can maintain indoor air fresh; At the same
time because this machine use evaporation cooling principle, therefore it has a cooling and
humidification double function (relative temperature up to around 75%), textile, knitting etc
workshop use, not only can improve when the temperature conditions, but also can purify air,
reduce needle broken wires in the process of this rate and improve the needle textile product
quality. Cooling fan (evaporative air conditioners) around the use of special material with wet
curtain honeycomb, with a great surface area, through the water cycle system to damp curtain
constantly increasing humidity In the wet curtain cooling fan with low noise high in energy
saving fan, when the fan operation, cold wet curtain of the fan produce negative pressure, and
make a cake layer air flowing through the porous wet wet curtain into the machines, because the
evaporation of water wet curtain absorb heat, forcing all the damp curtain of air cooling. At the
same time as the water on the wet curtain to damp curtain air flows through evaporation, and
increase the humidity in the air, so the cold wind damp curtain cooling machine has increased
wet double function
