Abstract
An integrated air conditioning system includes an outdoor unit, an indoor unit, and a ventilation device. The ventilation device includes a housing including an inlet flow path, and an outlet flow path, a total heat exchanger in which air flowing through the inlet flow path and air flowing through the outlet flow path exchange heat with each other, a first heat exchanger disposed on the inlet flow path to receive a refrigerant from the outdoor unit, a second heat exchanger disposed upstream of the first heat exchanger on the inlet flow path and connected to the first heat exchanger to be supplied with refrigerant discharged from the first heat exchanger, a first expansion device to expand the refrigerant supplied to the first heat exchanger from the outdoor unit, and a second expansion device to expand the refrigerant discharged from the first heat exchanger and supplied to the second heat exchanger.
