ABSTRACT:
A method and apparatus for controlling an air conditioner having a variable speed compressor to circulate a refrigerant in a refrigerating circuit. The control apparatus and method generates a rotational speed pattern which can be directly changed by a predetermined value through a controller operable by the user. The compressor rotational speed is also based on the rotational speed used in a previous operation of the compressor to take into account the time lag occurring between the time the air conditioner is operated and the time the conditioned air is actually circulated in the room. Basing compressor speed on previous operations of the compressor minimizes large fluctuations in room temperature due to inaccuracies in temperature detection.
