Evaporative air coolers, also known as swamp coolers, are devices that use the natural process of evaporation to cool the air in a space. These coolers draw warm air through water-saturated pads, where the water evaporates, resulting in a decrease in air temperature. The cooled air is then circulated into the environment, providing a refreshing and energy-efficient cooling solution. Evaporative air coolers are particularly effective in dry climates, and they are commonly used in homes, offices, and outdoor areas as an environmentally friendly alternative to traditional air conditioning systems. They are known for their cost-effectiveness and ability to add moisture to the air.
