PROBLEM TO BE SOLVED: To relax unevenness of the temperature distribution inside of a room wherein heating operation is performed. SOLUTION: A fan 17 for blowing air along a ceiling surface 10 is arranged near the ceiling surface 10 inside of the room 1 wherein the heating operation is performed, and a rectifying member 25 for rectifying downward flows to the parallel downward flows along a side surface 20 inside of the room 1 is arranged in an upper part near the side surface 20 inside of the room wherein the downward flows are generated by air-blow by the fan 17. When the air blown by the fan 17 and flowing along the ceiling surface 10 reaches the upper part near the side surface 20 inside of the room 1, the air changes direction to fall. In the air during a fall, a temperature grade is formed so that temperature becomes higher as it separates far from the side surface 20. COPYRIGHT: (C)2004,JPO
