Features: 1) Corrugated paper has high intensity structure, corrosive resistance, long service life 2) Fine percolating and absorbing water to ensure drip wet the wall 3) Specific stereoscopic structure. It can provide the largest evaporative surface for heating exchanging between weather and air 4) Outer frame can be alternative of aluminum alloy, PVC and galvanized board
Cooling system is with its cooling pad paper. There is a thin layer of water film on surface of wave-like fiber paper. When outdoor dry and hot air is drawn by fan through the wet cooling pad paper, the water of water film will absorb the heat in air and evaporate, taking away large amount of heat. Thus, the temperature of air going through the wet cooling pad paper is reduced. Through such treatment, the wet and cool air comes in house. After mixing with indoor hot air, exhausted by fans, and during cooling, the waste and dust in outdoor air are cleaned, which increases the amount of oxygen in air, makes indoor air fresher, and improves air quality in working environment.
