Evaporative air cooler use a fan to draw in outdoor fresh air, where it passes over water-moistened pads, it cools air through the evaporation of water, then swamp coolers release this cool moisturized air into the space, the temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation), this immediately cools the air.
Water air cooler vs air conditioner:
