PURPOSE: An air conditioner with ventilation, heating and cooling functions is provided to minimize stratification of indoor air by uniformly flowing heated air and cooled air by convection. CONSTITUTION: An air conditioner with ventilation, heating and cooling functions comprise a casing(131) and a supply duct. The casing is divided into a first area and a second area. A heat source supply unit and a heat exchange unit are separately installed in the first and second areas. The supply duct is installed in the first area, and discharges heated or cooled air to a lower or upper part of the casing through a supply fan. External air flowed from the outside is heat-exchanged with heated indoor air and supplied to the first area. First and second supply ducts(139a,135a) are installed in the casing. |
