Abstract
In an electric control method and apparatus for an automobile air conditioning system, an air-blend door is arranged between an evaporator and a heater within an air duct to control an amount of the cooled air flowing through the heater into a passenger compartment and to control an amount of the cooled air directly flowing into the compartment, and a refrigerant compressor for the evaporator is connected to a prime mover of the automobile when the air-blend door is opened to allow the cooled air flowing through the heater in a limited range and is disconnected from the prime mover when the air-blend door is further opened to allow the cooled air flowing through the heater beyond the limited range.
