cooling pad & exhaust fan system are made up of cooling pad,exhaust fan,water circulation and control device. With the theory of temperature drops when water evaporates,cooling pad & exhaust fan are installed in a closed house.When fans suction draft,there'll be negative pressure in this house.When air come through the cooling pad,water will evaporates.In this case, tempreture in house will drop between 4 degrees and *0 degrees.This system is widely used  in greenhouse,poultry house,industrial workshop,especially at the places which need to make tempreure drop and gain mouisture.It's comsuption of power is 1/*0 of air conditioner,installation cost of this system is about 1/7 of air conditioner
