greenhouse cooling fan and water pad position, effect distance less 40m is better
General cooling can reach 4-10 degrees, the higher the temperature, the more obvious the cooling effect of "water curtain wall + negative pressure extraction fan" cooling principle, through the negative pressure extraction fan will be indoor hot air, odor, dust and other outdoor discharge, at this time the indoor air pressure becomes low, indoor and outdoor air pressure difference forces the outside air through the "wet curtain" into the indoor, When the outside air passes through the water curtain, it will fully contact with the water film on the wet curtain (about 20 square meters of wet curtain film spread area of 100mm thick per square meter). The heat in the air will be absorbed by the water film instantly, and then change the temperature and humidity of the air intake, so that the indoor temperature is rapidly and significantly reduced.
