AIR CONDITIONER

PROBLEM TO BE SOLVED: To propose an air conditioner using drain water as humidifying water of a humidifier in order to reduce the discharge amount of drain water. SOLUTION: In the air conditioner 1, sucked air is cooled and dehumidified in an evaporator 9, heated by a heater 10, then humidified by the humidifier 11 having a humidifying water tank 19, and blown off to the outside. Drain water produced in the evaporator 9 is collected into a drain pan 31, and after impurities are removed via a demineralizer 15, the drain water is supplied to the humidifying water tank 19 of the humidifier 11. Since the drain water is used as the humidifying water, the discharge amount of drain water can be reduced. Further, since the drain water is evaporated after eliminating the impurities, the impurities are not accumulated in the humidifier 11. COPYRIGHT: (C)2008,JPO&INPIT
