Abstract: A control method for discharging condensed water from a movable air conditioner is provided. No manual operation is necessary to empty the condensed water container. When the condensed water level is higher than a predetermined water level, the conditioner enters into a strong drainage mode operation. Condensing temperature increases and a pump for spraying is activated. The evaporating and draining speed increase as well. Evaporated condensed water will be discharged outdoor as air discharged from the condenser by the exhaust pipe; the rest of the condensed water will flow downward from the condenser to a water tank. When condensed water level bellows the predetermined water level, the conditioner exits the strong drainage mode and enters into a normal operation mode. The heat exchange efficiency of the condenser is also improved by utilizing the condensed water spray circulation system.
