The invention discloses a double-layer-padding noiseless passive evaporative cooling ventilation air conditioning system used for a rural residence. The double-layer-padding noiseless passive evaporative cooling ventilation air conditioning system comprises a ventilation-cooling chimney arranged outside the residence, a cold air inlet window, and an air exhaust window, wherein the cold air inlet window and the air exhaust window are separately arranged on two opposite side walls of the residence. The ventilation-cooling chimney is connected with the cold air inlet window. The double-layer-padding noiseless passive evaporative cooling ventilation air conditioning system used for the rural residence has the characteristics of being low in energy consumption, good in cooling effect and capable of obviously improving the air quality in the residence.
