Abstract: Disclosed is a method of controlling an air conditioner including a step of sensing the capacitance of condensed water through any one of a plurality of electrode pads to sense the level of the condensed water during cooling, and a step of operating a drainage pump based on the level of the condensed water sensed through any one of the electrode pads to drain the condensed water stored in the condensed water storage part. A water level detecting device of the air conditioner more accurately senses the level of condensed water based on the capacitance of the condensed water, thereby effectively controlling the drainage pump.

Abstract: The air conditioner includes a sensing unit for sensing a breakdown or an operation state of a motor. The state of the motor is sensed using a non-contact type sensor, whereby it is possible to easily monitor the states of a compressor and a fan motor without modifying conventional air conditioners, to sense the progress of the abnormality of the compressor and the fan motor or whether the compressor and the fan motor have broken down, and to estimate the expected lifespan of the compressor or the fan motor based on the state thereof using the monitored results. Consequently, it is possible to prevent the damage to the air conditioner due to abnormality of the compressor or the fan motor.

Abstract: Provided are an air conditioner and a control method thereof. The air conditioner includes a compressor, an accumulator recovering a liquid refrigerant contained in a refrigerant flowing into the compressor, an outdoor heat exchanger performing heat exchange of air using the refrigerant, an outdoor unit fan supplying outside air to the outdoor heat exchanger and discharging heat-exchanged air, a refrigerant charging pipe connected to a refrigerant pipe and allowing the refrigerant to be additionally introduced from the outside, a refrigerant charging valve installed in the refrigerant charging pipe to open and close the refrigerant charging pipe, and a controller setting an operation mode so as to operate in a cooling operation or heating operation upon setting of a refrigerant charging mode, setting an operation frequency of the compressor in accordance with a load of an indoor unit upon the setting of the refrigerant charging mode to allow the compressor to operate at the set operation frequency during the refrigerant charging, and calculating the amount of refrigerant to stop the refrigerant charging when a predetermined reference value is reached.
