AIR CONDITIONER FOR AUTOMOBILE

PURPOSE:To enable upper and lower temperature distributions and a draft distribution to be controlled at will for comfortable air conditioning by using each mode door for both an air flow damper and a jet port change-over damper to operate each mode door steplessly according to thermal load. CONSTITUTION:In a duct casing 1 are incorporated a blower motor 2, an evaporator 3 and a heater core 4 respectively for a reheat air mix type air conditioner. Then, respective mode doors such as deforster door 8, vent door 9, floor door 10, etc., are used for both an air flow damper and a jet port change-over damper. And the respective mode doors 8-10 are operated steplessly according to thermal load. Also, the respective mode doors 8-10 are controllably opened and closed through a side link 21 by an actuator 22 according to the air conditioning mode. Then, on the basis of the respective detecting signals from an atmosphere sensor 26 and a sun beam sensor 31 is determined a desired jet temperature by a controller 25 to control comfortably upper and lower temperature distributions and a draft distribution.
