ABSTRACT:
An air conditioning apparatus for a vehicle for air conditioning only a zone adjacent a person sitting on a seat. A bottom duct 62 has inlets 60 which are located laterally of a sitting part 50 of the seat, and a top duct 70 has an outlet 72 located above a head rest portion 58 of the seat. Arranged in the bottom duct 62 is a blower fan 74, evaporator 78 and heater 80. The rotation of the fan 74 causes the air to be sucked into the duct 62 via the inlets 60, and is subjected to the heat exchange with the evaporator 78 and the heater 80 to obtain a desired temperature of the air. The air is discharged downwardly from the top outlet 72 to the bottom inlet 60, so that air flows for air conditioning are crated along an area only around the person sitting on the seat.
