Title: Air conditioning apparatus having electrical heating member

Abstract: In an air conditioning apparatus for a vehicle, plural electrical heating members are integrated with a heater core for heating air. The air conditioning apparatus includes a first control unit for determining number of the electrical heating members to be operated, and a second control unit for controlling electrical power supplied to each of the electrical heating members based on the number determined by the first control unit. The second control unit preferentially supplies electrical power to an electrical heating member plated at a side of a foot opening through which air blown toward a lower side of a passenger compartment. Thus, the lower side of the passenger compartment can be preferentially quickly heated by heat generated from the electrical heating members.
