Swamp coolers work best where the air is hot and dry, like in Arizona. In areas where humidity is generally high like Washington DC, Florida or the Dakotas, the swamp coolers don’t work as well because the air is already humid so the dripping pads are less effective at lowering the tem...
Artwork: How an evaporative cooler works. 1) Hot, dry air is sucked in through a grille. 2) The air passes through a pad soaked with cool water. 3) Some of the water evaporates, cooling the air and making it more humid. A fan blows the cooled, humid air back into the room. 4)...
Note: Evaporative coolers and mini personal air coolers do not produce a cooling effect that can be expressed in BTU. They use water evaporation instead of the refrigerant-based system to provide a cooling effect. You can also check a similar BTU calculator for heating here. We hope this help...
