PURPOSE:To improve the comfortability and energy-saving by a method wherein deflecting plates, which direct the air toward the floor at small air flow rate and toward the floor and the ceiling at large air flow rate, are provided in a wall heating equipment main body. CONSTITUTION:A step motor 6 is driven inproportion to air flow rate so as to change the opening angle alpha of the deflecting plates 5 and 5' in such a manner that the opening angle alpha is turned to be small at small air flow rate and turned to be large at large air flow rate. Consequently, the air at small air flow rate is blown-off toward the floor, resulting in minimizing the sum of senses of discomfort based upon the air velocity around human body and upon the vertical temperature difference within a room. The air at large air flow rate is blown- off toward the floor and the ceiling, because the opening angle alpha being increased, resulting in enabling to keep the vertical temperature within the room constant without the increase of the air velocity around human body. In such a manner as described above, the improvement of comfortability and of energy- saving can be realized. |
