Negative-Pressure Air Agriculture Ventilation Barn Exhaust Fan for Greenhouse
cooling system is made up with Paper porous wet curtain, water circulation system, fan .When the unsaturated air flows through the porous wet curtain surface a large amount of moisture evaporates and the sensible heat in the air changes from the sensible heat reflected by temperature to the latent heat of evaporation thus reducing the temperature of the air itself. Fan draught will pass through the wet curtain cooling cold air flowing into the room, so as to achieve cooling effect.
