Evaporative coolers, also known as swamp coolers, are devices that use the natural process of evaporation to cool the air. They work by drawing hot, dry air through moistened pads, where the air is cooled as the water evaporates. This cooled air is then circulated into the living space, providing a refreshing and cost-effective alternative to traditional air conditioning systems. Evaporative coolers are commonly used in dry climates where humidity levels are low, as they rely on dry air to effectively cool the environment.
