Abstract: An air conditioner and a method of controlling the same are disclosed. The air conditioner includes a controller configured to determine a target evaporation pressure based on information sensed by an outdoor temperature sensor. The controller determines whether the determined target evaporation pressure is changed, based on a difference between a value sensed by an indoor temperature sensor and a set temperature of an indoor space and a value sensed by an indoor humidity sensor.

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 is provided. The air conditioner may include a compressor, a condenser, an evaporator, a receiver storing a portion of a refrigerant passing through the condenser, an accumulator receiving refrigerant stored in the receiver and refrigerant passing through the evaporator to separate gas refrigerant from refrigerant introduced therein and supply the gas refrigerant to the compressor, and a bypass line supplying refrigerant from the receiver to the accumulator. The receiver and the accumulator may be integrally formed or provided as separate parts coupled each other. An outlet end of the bypass line may be connected to an upper portion of the accumulator. Such an arrangement may prevent refrigerant from flowing backward from the accumulator into the receiver.
