An integrated air conditioner with a fan casing is provided to reduce flowing resistance of air discharged therefrom, and to achieve increase of wind flow rate and reduction of noise owing to air discharged therefrom. The fan casing includes a fan-housing unit having a volute space in which a blower fan is rotatably mounted and an outlet space combined with the volute space. The volute space of the fan-housing unit is provided at an inner top surface of the volute space with a concave recess leading to an upper surface of the outlet space such that the overall inner surface of the volute space takes a shape of Archimedes' spiral. The fan casing also includes a front panel attached to a front face of the fan-housing unit, which is provided with an air intake opening and a turning plate bent forward. The turning plate defines an outlet duct by combination with the outlet space to direct room air in the volute space to a front air outlet through the outlet space.
