Abstract
An air conditioner is provided that includes a compressor that compresses a refrigerant; an accumulator that supplies the refrigerant to the compressor; a condenser that condenses the refrigerant discharged from the compressor; an expansion valve that expands the refrigerant having passed through the condenser; an evaporator that includes a heat exchange pipe through which the refrigerant having passed through the expansion valve flows, and that evaporates the refrigerant flowing through the heat exchange pipe; a gas-liquid separation pipe that connects a first point and a second point located between a first end and a second end of the heat exchange pipe; and a bypass pipe a first end of which is connected to the gas-liquid separation pipe and a second end of which is connected to the accumulator. The gas-liquid separation pipe includes a first portion a first end of which is connected to the first point and a second end of which is connected to one end of the bypass pipe; and a second portion that extends from the first point between the first end and the second end of the first portion, and is connected to the second point.
