The air cooler works by evaporating water. Water absorbs heat from the air as it evaporates, thus cooling the environment. The air enters the device, passes through wet filters, and is cooled before being returned to the room.
How much water does an air cooler consume?
Water consumption depends on the size of the device and the operating time. Typically, an air cooler needs regular refilling of the water tank, which can take anywhere from a few hours to a full day, depending on the size of the tank and operating conditions.
