The ACP50E is an evaporative air cooler that cools the air by means of evaporation. When water evaporates into the air the result is a mixture of air and water molecules. This chemical change requires heat which is taken from the water molecules resulting in a spot cooling effect the temperature drop. The air is passed through a special honeycomb cooling pad which expands the evaporation surface and improves the cooling effect while doubling as an air filter. The evaporative coolers must be used in rooms or spaces with good ventilation otherwise the room will get saturated with humidity and the effect of cooling will stop..
