ABSTRACT:
A structure of an air conditioning apparatus applicable to a vehicle compartment is disclosed. In the air conditioning apparatus, a heater core for heating an introduced air is disposed in a heating unit casing so as to be in parallel to an air stream passage derived from an air cooling unit or inclined through a predetermined air suppression angle with respect to the air stream so that air resistance of the heater core against the air stream is minimized and a higher cooling characteristic can be achieved. In addition, a door member disposed on an upstream end surface of the heater core for mixing cooled and heated air is substantially aligned with an extension line of an air output side surface of the heater core in a maximum cooling mode of operation of the apparatus. Furthermore, a space within the heating unit casing for a main air stream passage derived from the air cooling unit is sufficiently secured so that a dimension of the heating unit can be saved to meet a requirement for mounting the air conditioning apparatus into a predetermined position of a limited space of the vehicle compartment.
