An air cooler, also known as an evaporative cooler, is a portable device designed to lower the temperature of a room or small area by using the natural process of water evaporation. Unlike traditional air conditioners, air coolers do not use refrigerants or complex machinery, making them more energy-efficient, eco-friendly, and cost-effective
The air cooler operates by drawing in warm air from the environment using a built-in fan. This air passes through a wet cooling pad or filter, which is kept moist by water from an internal tank. As the warm air moves over the damp pad, the water evaporates, absorbing heat from the air and cooling it down. The fan then blows this cooler, more humidified air back into the room, creating a refreshing breeze
