1. An air conditioner, comprising:
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-passing having passed through the condenser;
an evaporator has that includes a heat exchange pipe through which the refrigerant having passed through the expansion valve flows, and evaporates 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 the other 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, wherein the gas-liquid separation pipe comprises:
a first portion a first end of which is connected to the first point and a second end of which is connected to the first end of the bypass pipe; and
a second portion that extends from the first portion between the first end and the second end of the first portion, and is connected to the second point;
a header into which the refrigerant having passed through the bypass pipe flows;
a pipe that is installed between the header and the accumulator, and provides a passage for the refrigerant between the header and the accumulator; and
a valve that is installed in the pipe, and opens and closes the passage of the pipe, and wherein the gas-liquid separation pipe comprises:
a first gas-liquid separation pipe; and
a second gas-liquid separation pipe which is spaced apart from the first gas-liquid separation pipe with a portion of the heat exchange pipe interposed therebetween, wherein the bypass pipe comprises:
a first bypass pipe connected to the first gas-liquid separation pipe; and
a second bypass pipe connected to the second gas-liquid separation pipe, and wherein the header comprises:
a first header into which the refrigerant having passed through the first bypass pipe flows; and
a second header into which the refrigerant having passed through the second bypass pipe flows.
