Abstract
An air conditioning apparatus includes a casing having intake and blow-out ports, a partition member dividing an interior of the casing, a heat exchanger and a centrifugal fan. The centrifugal fan includes a hub and a bladed wheel having a plurality of rearward blades and sucks air existing in the heat exchanger compartment into the fan compartment through the fan entrance. The bladed wheel is mounted in the fan compartment such that a rotary shaft of the bladed wheel is oriented along an opening direction of the fan entrance and an opening direction of the blow-out port. The hub connects blow-out port side ends of the plural rearward blades and is configured to be rotated about the rotary shaft. The hub has an outer diameter smaller than an outer diameter of the rearward blades.
