摘要： The present invention discloses an improved air conditioning system which can supply fresh air prepared separately. A first preferred embodiment of the present invention provides an air conditioning system including an outdoor unit, an indoor unit installed in a ceiling, and means connected to the indoor unit for supplying fresh air stored separately to the indoor unit. A second preferred embodiment of the present invention provides an air conditioning system including an outdoor unit, an indoor unit, air supply and air discharge ducts, and means connected to the air supply duct for supplying fresh air stored separately to the indoor unit. In the second embodiment, the indoor unit includes a fan, an indoor heat exchanger, and a guide duct for guiding flow passages of the external air and room air, and, if necessary, further including a preheat exchanger arranged to surround the guide duct for indirect heat exchange between the external air and the indoor air.

摘要： Air conditioning system including an outdoor unit, a compact indoor unit, air supply duct, air discharge duct, and preheat exchanger. An indoor heat exchanger in the indoor unit has a space therein in communication with a room, a fan in the indoor unit provided in the space draws air and discharges through the indoor heat exchanger. A ventilation guide duct in the indoor unit on an underside of the indoor heat exchanger has a partition wall for separating external air supplied from an outside of the room, and room air, for guiding the external air to the room through the fan, and the room air to the outside of the room. The air supply duct and the air discharge duct have one ends connected to the ventilation guide duct for guiding the external air to the room, and the room air to the outside of the room, respectively. The preheat exchanger is provided in the middle of the air supply duct and the air discharge duct, for indirect heat exchange of the external air and the room air passing through the air supply duct and the air discharge duct.
