Abstract: The air conditioner may include 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 states of a compressor and a fan motor, to sense 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. Damage to the air conditioner may be prevented due to abnormality of the compressor or the fan motor.

Abstract: An air conditioner and a method for controlling the same for securing reliability and increasing efficiency are provided. The air conditioner and the method of controlling the same detect freezing occurring in the heat exchanger of the outdoor unit, determine a time of the defrosting operation according to a freezing degree such that the defrosting operation is performed, thereby preventing cooling/heating operation efficiency and capability due to a frequent defrosting operation from being deteriorated. The air conditioner and the method of controlling the same according to the present invention provide comfort of a predetermined level to the user to solve deterioration of convenience, and remove freezing due to a defrosting operation to thereby improve efficiency during cooling/heating operations.

Abstract: An air conditioner and a method of controlling an air conditioner are provided. The air conditioner may include a compressor, an accumulator that recovers a liquid refrigerant contained in a refrigerant flowing into the compressor, an outdoor heat exchanger that performs heat exchange of air using the refrigerant, an outdoor unit fan that supplies outside air to the outdoor heat exchanger and discharges heat-exchanged air, a refrigerant charging pipe connected to a refrigerant pipe and allowing the refrigerant to the 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 that sets an operation mode so as to operate in a cooling operation or a heating operation upon setting of a refrigerant charging mode, sets 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 calculates an amount of refrigerant in order to stop the refrigerant charging when a predetermined reference value is reached.
