Abstract
An air conditioner includes an air inlet, an air outlet, a fan for circulating air from the inlet to the outlet, and a heat exchanger for heating or cooling the circulated air. Inlet and outlet doors are provided which can be moved between opened and closed states. In their closed states those doors prevent dust and other foreign substances from entering the air conditioner. Motors are provided for opening and closing the doors, and detectors sense whether the doors have been fully opened or closed. A controller operates the motors on the basis of a user-selected mode of operation, and the detected door positions.
