Abstract: An automobile air-conditioning system in which a single ventilation unit for supplying the conditioned air to a compartment is divided into two parts, and the air passing through each part is adapted to be controlled respectively. The compartment is divided into at least three air-conditioning zones of the front right, front left and rear seat zones so that a plurality of air outlets may supply air to the respective air-conditioning zones. The air respectively temperature-controlled is selectively supplied to each of the air outlets.

Abstract: In an air conditioner control method and apparatus, an air flow direction control device is arranged to be adjusted to at least first and second positions in which an air flow is directed respectively to first and second portions in a compartment, and the air flow direction control device is adjusted to its first and second positions in response to each lapse of first and second periods of time which are respectively calculated to maintain the air flow direction toward the first and second portions in the compartment in relation to any deviation between the actual temperature in the compartment and a desired temperature, the air flow direction control device being maintained at the adjusted position during each of the calculated first and second periods of time.
