Abstract:
An air conditioner is provided. The air conditioner may include a compressor, a condenser, an expansion device and an evaporator. The condenser or the evaporator may include a heat exchange tube formed of an aluminum material and allowing refrigerant to flow therein, and a fin connected to the heat exchange tube, the fin being formed of the same metal material as that of the heat exchange tube so as to prevent potential corrosion of the heat exchange tube.
Abstract:
An air conditioner is provided. A location of, an angle between, or a distance between, a heat exchanger and a blower may be varied based on whether or not the air conditioner is operating. A number of drivers for moving the heat exchanger and/or the blower may be reduced and reliability of the driver be enhanced. Size of the air conditioner may be reduced, and efficiency may be improved.

Abstract:
A motor control apparatus and method are provided. The motor control apparatus may include a power supply device supplying power to a motor, a power control device selectively blocking current supplied to the motor depending on whether or not the current supplied from the power supply device to the motor is greater than a reference current value, a controller that controls an intensity of the current supplied from the power supply device to the motor, and a load torque detector that detects a load torque generated by the motor as the motor rotates. The controller controls a maximum value of the current to be supplied to the motor so that the maximum value is less than the reference current value when the maximum value of the load torque detected by the load torque detector is greater than a maximum motor output due corresponding to the reference current value.
Abstract:
An indoor unit of an air conditioner is provided. A width of the indoor unit of the air conditioner may be varied based on whether or not the indoor unit of the air conditioner is operated.
Abstract:
A device and method for reducing vibration in a compressor are provided. The device for reducing vibration in a compressor may include a compressor controlled to be operated at a target operating velocity after starting; a power supply that supplies power to the compressor; and a controller that controls the power supply so that a magnitude or a phase of the power supplied to the compressor is changed. The controller may control the power supply so that vibration generated in the compressor is offset by an exciting force generated in the compressor within a predetermined time interval multiple times when the compressor starts or when the compressor stops during a target operation velocity operating of the compressor.
