Cooling Principle of cooling pad:：
The cooling pad is made from special paper with honeycomb structure, and its operation principle is a physical phenomenon “evaporating water, taking in heat”.That’s to say, acted by the gravity, the water flow up-down to form a water film on the surface of the wave-like fiber paper. When the outdoor dry and hot air is drafted by fan through the wet cooling pad, the water in the water film will take in the heat and evaporate, taking away large amount of heat, cooling the air to make the inner door air fresher, cooler and wetter.
Negative-pressure cooling principle: Its operation principle is a physical phenomenon “evaporating water, taking in heat”. Installing fans in one side of a closed workshop and equipping cooling pads in the other. The fan will draft the hot air away, and negative-pressure will be in the room to make a pressure gap between inside and outside, then, the air outside through the cooling pad will be cooled, exchanging the heat with the inside air to make the inner door air fresher, cooler and wetter.
