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.
Claims12
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 the outdoor unit through a liquid refrigerant pipe, a high-pressure refrigerant pipe, and a low-pressure refrigerant pipe, and configured to supply the outside air to 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;
- a refrigerant distributor connected to the liquid refrigerant pipe, the high-pressure refrigerant pipe, and the low-pressure refrigerant pipe, 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, and discharge the refrigerant from each of the main heat exchanger and the recovery heat exchanger to the outdoor unit;
- and
- a re-heat heat exchanger disposed in the supply flow path, connected to the high-pressure refrigerant pipe, and configured to heat air flowing through the supply flow path,
- wherein a liquid pipe control valve is disposed in the liquid refrigerant pipe and configured to control an amount of refrigerant supplied from the outdoor unit to the refrigerant distributor.
