Abstract: An air conditioner including an outside unit, which includes 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.

Abstract: An air conditioner is provided. The air conditioner may include a compressor to compress a refrigerant, at least one oil sensor disposed in the compressor to detect oil stored in the compressor, an oil separator to separate the oil from the refrigerant discharged from the compressor, a first collection tube to collect the oil separated by the oil separator into the compressor, a second collection tube disposed at a height different from a height of the first collection tube, an oil valve disposed in the second collection tube, and a controller to control the oil valve on the basis of information detected by the oil sensor.

Abstract: An oil separator and an air conditioner using the same are provided. The air conditioner may include at least one indoor unit connected to an outdoor unit by a refrigerant tube. The outdoor unit may include a compressor and an oil separator including a plurality of oil recovery tubes introducing oil into the compressor. The oil separator may include a housing, a suction tube guiding oil-mixed refrigerant into the housing, a discharge tube discharging refrigerant separated from the oil-mixed refrigerant, and first and second recovery tubes discharging oil separated from the oil-mixed refrigerant. At least one of the first or second recovery tubes may include an oil valve guiding a movement direction of the oil.
