JP2531287B

PURPOSE:To prevent a floating of blown conditioned air by a method wherein a detected data from a heat exchanging temperature sensing means is inputted as an input signal during a heating operation and in the event that the detected data is more than a set value, means is provided for outputting an instruction to vary a set angle of the horizontal vane downwardly in respect to the first driving means. CONSTITUTION:A heat exchanging temperature sensing means 33 is provided for sensing a temperature of a heat exchanger 7. Then, during a heating operation, the detected data from the heat exchanging temperature sensing means 33 is inputted to a control means 34 as an input signal. In the event that the detected data is more than the set value, an instruction for varying the set angle of the horizontal vane 10 by one step only in respect to the driving means 12 is outputted from the control means 34. With such an arrangement, a floating of the blown conditioned air can be eliminated and a comfortable indoor dwelling environment can be improved.
