Air conditioner

An air conditioner, comprising:

• an outdoor unit including a compressor configured to compress a refrigerant and an outdoor heat exchanger configured to exchange heat between the refrigerant and outside air;
• and
• a ventilation device connected to a plurality of refrigerant pipes, and configured to supply the outside air into an indoor space, and discharge indoor air to an outside,
• wherein the ventilation device comprises:
• a case defining a supply flow path through which the outside air is supplied to the indoor space, and a discharge flow path through which the indoor air is discharged to the outside;
• a main heat exchanger disposed in the supply flow path, and configured to exchange heat between air flowing in the supply flow path and the refrigerant;
• a recovery heat exchanger disposed in the discharge flow path, and configured to exchange heat between air flowing in the discharge flow path and the refrigerant;
• and
• a refrigerant distributor connected to the plurality of refrigerant pipes, the refrigerant distributor being configured to supply the refrigerant from the outdoor unit to each of the main heat exchanger and the recovery heat exchanger, discharge the refrigerant from each of the main heat exchanger and the recovery heat exchanger to the outdoor unit, and direct the refrigerant between the main heat exchanger and the recovery heat exchanger.
