Abstract
An air conditioning apparatus for a vehicle includes a front air-conditioning unit for adjusting a temperature of air blown toward a front seat side in a passenger compartment, and a rear air-conditioning unit for adjusting a temperature of air blown toward a rear seat side in the passenger compartment. In the front air-conditioning unit, a ratio between an amount of air passing through a front heater core and an amount of air bypassing the front heater core is adjusted by an air mixing door, and the temperature of air blown toward the front seat side in the passenger compartment is adjusted by the rotation of the air mixing door. On the other hand, in the rear air-conditioning unit, a flow control valve for controlling a flow rate of hot water flowing into a rear heater core is provided, and the temperature of air blown toward the rear seat side in the passenger compartment is adjusted by the flow control valve. Thus, the air conditioning apparatus has a downsized rear air-conditioning unit while preventing air-conditioning capacity for the passenger compartment from being lowered.
