ABSTRACT:
In a unit case of a vehicle air conditioning apparatus, air mix chamber is not provided. Cooled air cooled by an evaporator and heated air heated by a heater core are directly introduced to a face opening and a foot opening of the case and then mixed in a face duct and a foot duct. The case has a guide for directing a flow of the heated air or the cooled air. The guide, the foot opening and the face opening are arranged such that the amount of heated air passing through the foot opening is larger than that of the cooled air and the amount of cooled air passing through the face opening is larger than that of the heated air in a bi-level mode. Accordingly, a temperature of air blown from a foot outlet into a passenger compartment is different from that of air blown from a face outlet.
