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.
