Evaporative coolers, also known as swamp coolers, are a type of air conditioning system that cools the air through the evaporation of water. They work by drawing warm air through a damp pad or filter, which causes the water to evaporate and lower the temperature of the air. This cooled air is then circulated back into the room. Evaporative coolers are an energy-efficient and eco-friendly alternative to traditional air conditioning units, as they use less electricity and do not rely on harmful refrigerants. They are particularly effective in dry climates, where humidity levels are low.
