2. Description of the Prior Art
A conventional air conditioning system installed on the floor of an upper storey has a wind exhausting faceplate provided close to and connected with an indoor engine by a wind duct, so that cold air can be sent out through the wind outlets of the wind exhausting faceplate. As the wind guiding plates of the wind outlets are fixedly formed integral, cold air around the wind outlets is stronger than that far from them, unable to cool a room evenly. Therefore, a plurality of wind exhausting faceplates have to be provided at different locations on a ceiling and connected by comparatively long wind ducts. Under this condition, cold air conveyed through different-length wind ducts cannot evenly maintain its original cold temperature, failing to supply a room with even cold air.

At least one wind exhausting faceplate is connected with the return-wind box by a wind duct, having wind exhausting openings, with a cold wind chamber assembled above the wind exhausting openings and having a wind inlet connected with the wind outlet of the return-wind box by a wind duct. At least one motor fan is assembled with the wind exhausting faceplate.
A second feature of the invention is a return-wind box provided with at least one wind outlet. A return-wind faceplate is assembled at the lower side of the return wind box, having at least one return-wind inlet. At least one evaporator is assembled on the return-wind faceplate. At least one wind exhausting faceplate is connected with the return-wind box by a wind duct, having wind exhausting openings, with a cold wind chamber assembled above the wind exhausting openings and having a wind inlet connected with the wind outlet of the return-wind box. At least one motor fan is assembled on the return-wind faceplate.
A third feature of the invention is a return-wind box provided with at least a wind outlet. At least one evaporator is installed in the return-wind box to face the wind outlet of the return-wind box. A faceplate is assembled at the lower side of the return wind box, having a return-wind inlet and at least one wind exhausting opening, with cold wind chamber positioned above the wind exhausting opening and having a wind inlet communicating with the wind outlet of the return-wind box. At least one motor fan is installed in the cold wind chamber to face the wind exhausting opening of the faceplate.
