Abstract
An air conditioner includes an air inlet, an air outlet, a heat exchanger, and a suction source for sucking-in air through the inlet and then discharging the air through the outlet after passing the air across the heat exchanger. Vanes are provided for opening and closing the inlet. A drive mechanism rotates the vanes about respective horizontal axes such that the vanes become opened by progressively greater amounts in a direction away form the suction source to expose progressively larger areas of the air inlet. This achieves a substantially uniform rate of air flow throughout the height of the air inlet.
