Abstract: An air conditioner includes an outdoor unit including a compressor for compressing a refrigerant and an outdoor heat exchanger for exchanging heat between the refrigerant and outside air. A ventilation device is connected to a plurality of refrigerant pipes, and configured to direct outside air into an indoor space, and indoor air to the outside. The ventilation device includes a case, a main heat exchanger, a recovery heat exchanger, and a refrigerant distributor. The refrigerant distributor is configured to direct the refrigerant between the main heat exchanger and the recovery heat exchanger.

Abstract: An air conditioner includes an outdoor unit including a compressor for compressing a refrigerant and an outdoor heat exchanger for exchanging heat between the refrigerant and outside air. A ventilation device is connected to the outdoor unit through a liquid refrigerant pipe, a high-pressure refrigerant pipe, and a low-pressure refrigerant pipe. The ventilation device supplies the outside air to an indoor space, and discharges indoor air to the outside. The ventilation device includes a case, a main heat exchanger, a recovery heat exchanger, a refrigerant distributor, and a re-heat heat exchanger. A liquid refrigerant pipe valve is disposed in the liquid refrigerant pipe for controlling an amount of refrigerant.

Abstract: An air conditioner includes an outdoor unit having a compressor and an outdoor heat exchanger. A ventilator connected to the outdoor unit by refrigerant pipes allows outside air to pass through a heat exchanger and flow into an indoor space, and allows indoor air to pass through the heat exchanger and flow to an outdoor space. The ventilator includes a supply passage through which the outside air flows into the indoor space, and a discharge passage through which the indoor air is discharged to the outdoor space. The ventilaro also includes a main heat exchanger in the supply passage and a recovery heat exchanger in the discharge passage. A refrigerant distributor supplies the refrigerant from the outdoor unit to the main heat exachager or the recovery heat exchanger, vice-versa. A reheat exchanger in the supply passage heats the air flowing therethrough.
