Filtration system: Pad also has ventilation and corrosion, dust and dirt in the air with excellent filtering effect, is non-toxic and odorless clean humidifiers, oxygen cooling of environmentally friendly materials, it is also used for air purification and filtration media. Cooling principle wet curtain wall; wet curtain wall common to negative pressure ventilation cooling mode. Negative pressure ventilation and cooling mode, the suction fan for the room dirty, hot air pumped, and installed in the opposite suction fan wet curtain wall is used for air intake. Fresh outdoor hot air passes through the wet curtain wall was wet hole, with water filtration and heat exchange cooling. The origin of the name; because it is usually mounted on the wall factories, cafes, greenhouse wet screens, similar to wet curtain wall market, so called wet curtain wall outside the solar radiation intensity: 900W / M2 calculate the required ventilation After the amount of wet curtain factory, in determining the wet curtain area to be considered a proper balance between the wet curtain of efficiency, resistance and economy. The more wet curtain installation, of course, the better the cooling effect, ventilation resistance is also smaller, but higher investment; and vice versa. Therefore, we recommend selection based on experience following the curtain wind speed: 100 mm Wet curtain: 1.2-1.5 m / s wet curtain market _ China and China Qingzhou temperature control equipment (certified) _ Zhucheng wet curtain Chinese citizens from Qingzhou temperature control equipment factory available.
