Abstract
An air conditioner for an automotive vehicle having an air conditioner compressor driven with a crankpulley of an internal combustion engine, with an electromagnetic clutch energized, and linked with an evaporator for cooling and dehumidifying the intake air and an air mixing door located upstream of a heater core for heating the intake air. In such a conventional air conditioner there is provided, in addition to a manipulating lever located on a control panel and first switch indicated by A/C switch for actuating the clutch of the air conditioner compressor, a first engagement mechanism linked with said manipulating lever and engaged with a lever attached to the air mixing door for adjusting the degree of opening of the air mixing door so as to determine the quantity of air passing through the heater core according to the position to which the manipulating lever is moved in the heating direction with the first switch turned off, a second switch connected in parallel with the first switch which turns on in response to a temperature signal from a temperature sensing means adjacently located downstream from the evaporator, and a second engagement mechanism linked with the manipulating lever and with the second switch for adjusting the on-and-off time period of the second switch according to a position to which the manipulating lever is moved in the cooling position, with the first switch turned on, whereby the air conditioner compressor is actuated efficiently so that an engine fuel can be saved remarkably.
