Abstract: An air conditioning apparatus for a rear seat of a vehicle includes a centrifugal fan disposed at a downstream air side of an evaporator. The centrifugal fan is a backward curved fan having a plurality of blades each of which is curved backward relative to a rotation direction of the centrifugal fan. In the centrifugal fan, because a main component of velocity vector is in a radial direction of the centrifugal fan, a dynamical-pressure component of air blown from the centrifugal fan can be effectively changed to a hydrostatic-pressure component. Thus, during a cooler mode where air is simultaneously blown from first and second air outlets toward the rear space of the passenger compartment, a pressure of air blown from the first and second air outlets can be increased, and an amount of air blown toward the rear space of the passenger compartment can be sufficiently increased.

Abstract: A deodorizing filter for adsorbing malodorous particles in air is disposed at a downstream air side of a circumferential wall of an inside/outside air switching rotary door which opens and closes inside and outside air intake ports. A gap having a predetermined distance is provided between the deodorizing filter and the circumferential wall of the rotary door. The deodorizing filter is rotated integrally with the rotary door. When the rotary door is rotated to open both the outside and inside air intake ports at their intermediately opened positions, the inside air flowing from the inside air intake port directly flows into an outlet side of an inside/outside air switching box, and the outside air introduced from the outside air intake port passes through the gap and the deodorizing filter and flows into the outlet side of the inside/outside air switching box.
