Air conditioning apparatus having electric heating member integrated with heat exchanger

摘要

An air conditioning apparatus for a vehicle includes a heat exchanger for heating air to be blown into a passenger compartment of the vehicle using hot water as a heating source, a plurality of electric heating members formed integrally with the heat exchanger, and a control unit for controlling electric power supplying to the electric heating members and an amount of air blown from a blower. The control unit controls the amount of air blown from the blower based on a heat-radiating amount from the electric heating members and a target temperature of air blown into the passenger compartment. Thus, even when number of the electric heating members to be turned on is changed, the temperature of air blown into the passenger compartment can be set to the target temperature by controlling the amount of air blown from the blower. As a result, the passenger compartment can be effectively quickly heated using the electric heating members.
