<p>PURPOSE:To improve a stability in control and further improve a comfortable feeling in an air conditioning operation by a method wherein when a far infra-red ray input value from a light emitting means is more than the first set value, a person is detected, an air blowing duct is stopped at that position and in turn when the input value is lower than the second set value, a moving action of the person is detected and the air blowing duct is controlled in such a way as it is rotated toward the moving direction of the person and when a signal for sensing a person moving in an opposite direction is received, the air blowing duct is forcedly rotated in an opposite direction by a specified angle, thereafter the air blowing duct is stopped for a specified time interval. CONSTITUTION:In the event that far infra-red ray input values from a pair of light emitting means H1 and H2 to a light emitting means J are higher than the first set value, a person sensing signal is outputted from a person sensing means 101. After that operation, if the far infra-red ray input value from one light emitting means is lower than the second set value, a person moving signal is outputted by means 102 for sensing the movement of the person. When the person sensing signal is outputted by a duct control means 103, the air blowing duct 16 is stopped at that position and when the person moving signal is outputted, a duct driving means 2 is controlled in such a way as the air blowing duct 16 is rotated toward the moving direction of the person.</p> |
