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.

A structure of an air conditioning apparatus comprising: (a) a casing having at least one air inlet at one end thereof and at least one air outlet at the other end thereof, air outside the casing being introduced into an internal space of the casing via the at least one air inlet and formed into an air stream within the internal space and the air stream formed within the casing being supplied into a limited space via the at least one air outlet; (b) a blower unit installed at the one end of the casing adjacent to the at least one air inlet for blowing the introduced air toward the other end of the casing to form the air stream; (c) first means disposed downstream of the blower unit for cooling the air stream; (d) a heater unit disposed downstream of the first means for heating the air stream passed through the first means to supply a heated air stream to the limited space via the at least one air outlet, the heater unit having an elongated rectangular shape in section including a pair of opposed first and second walls and a pair of opposed elongated third and fourth walls, the elongated third and fourth walls of heater unit being disposed substantially parallel to the air stream exiting from the first means so as to minimize air resistance against the air stream with a bypass air stream passage being defined by the second wall and a first wall of the casing; (e) a first air mixing door member having a pivotal end located at a portion of the internal space adjacent to and upstream of the first wall of the heater unit for adjusting an amount of the air stream to be passed through the heater unit; and (f) a first partitioning member disposed between a position at which the first air mixing door member is placed in a maximum cooling mode within the internal space and a substantial half portion of the third wall of said heater unit so that a first air stream passage is formed so as to face toward an upstream first half portion of the third wall and a second air stream passage is formed so as to face toward a downstream second half portion of the third wall, the bypass air passage placed between the second heater unit wall and the first wall of the casing also being formed.
