Abstract: An air conditioner is provided that may include a defrosting bypass valve disposed at a defrosting bypass pipe having a first end connected to a middle point of the outdoor heat exchanger and a second end connected to an inlet pipe of a compressor, and a processor configured to open and close the defrosting bypass valve according to a temperature of a refrigerant in an outdoor heat exchanger. At a beginning of a defrosting operation, the processor may open the defrosting bypass valve to bypass a portion of the refrigerant in the outdoor heat exchanger to the inlet pipe of the compressor, and if the temperature of the refrigerant in the outdoor heat exchanger exceeds a predetermined temperature, the processor may close the defrosting bypass valve, thereby achieving defrosting performance at an early stage of the defrosting operation.

Abstract: An air conditioner and a method of controlling the same are provided. The air conditioner includes an outdoor unit provided with a compressor, an outdoor temperature sensor, an outdoor humidity recognition part, and a control part. The outdoor temperature sensor is installed on the outdoor unit to sense outdoor temperature. The outdoor humidity recognition part is installed on the outdoor unit to recognize outdoor humidity information. The control part controls an operation of the compressor, based information sensed from the outdoor temperature sensor and the outdoor humidity recognition part. When the outdoor temperature has a preset value, the control part determines target evaporation temperature such that the target evaporation temperature is decreased as outdoor humidity increases, and the control part drives the compressor at an operation frequency corresponding to the determined target evaporation temperature.

Abstract: An air conditioner and a method of controlling the same are provided. The air conditioner includes an outside unit, which is provided with a compressor and an evaporator, an outside temperature sensor attached to the outside unit to sense outside temperature, an outside humidity recognition part attached to the outside unit to recognize information about outside humidity, a low pressure sensor that senses an evaporation pressure of the evaporator, and a control part that controls an operation of the compressor, based on both information about dew-point temperature sensed from the outside temperature sensor and the outside humidity recognition part and information about the evaporation pressure sensed from the low pressure sensor. The control part changes an operation frequency of the compressor according to whether the evaporation pressure is not lower than a preset reference low pressure, to prevent frosting of the evaporator.
