  • Air conditioner with fan speed controlled by oscillating louver position
    Patent number: 5385031
    Abstract: A rotational speed of a fan is maintained at a preset one when an angle of a flap is at a maximum air-flow angle, increased by a specified value when the angle of the flap has been changed by a specified angle in the direction away from the position of the maximum air-flow angle, and decreased by a specified value when the angle of the flap has been changed by a specified angle in the direction toward the position of the maximum air-flow angle. It is possible to prevent any occurrence of condensation and air-flow pulsating noise without needing any complex control such as load response control and yet without requiring any complicate construction in the flap.
