1. An automotive air conditioning system comprising:
- a heater for heating air sent out into a passenger compartment;
a face outlet provided on a downstream side of the heater as viewed along the flow of air for sending out air toward faces of occupants in the passenger compartment;
a foot outlet provided on the downstream side of the heater as viewed along the flow of air for sending out air toward feet of the occupants in the passenger compartment;
a target air-outlet temperature (TAO) calculating unit for calculating a target air-outlet temperature (TAO) for air sent out into the passenger compartment;
an outlet mode setting unit for setting at least a bilevel mode in which the face outlet and the foot outlet are opened at the same time and a foot mode in which the face outlet is closed, whereas the foot outlet is opened;
a heating source for heating a heating medium supplied to the heater; and
a control unit configured to control operation of the heating source such that the heating capacity of the heater for the target air-outlet temperature (TAO) during an operation in the bilevel mode becomes larger than the heating capacity of the heater for the target air-outlet temperature (TAO) during operation in the foot mode.

Abstract
In a hybrid vehicle air conditioning system in which coolant is supplied to a heater core from a vehicle running engine, for heating, a demand of the operation of the vehicle running engine is controlled to obtain respective set coolant temperatures TWS2 for target air-outlet temperature TAO of air sent out into a passenger compartment during a bilevel mode operation and TWS1 for the target air-outlet temperature TAO during a foot mode operation by setting the set coolant temperature TWS2 higher than the set coolant temperature TWS1.

7. An automotive air conditioning system comprising:
-
a heater for heating air sent out into a passenger compartment; a face outlet provided on a downstream side of the heater as viewed along the flow of air for sending out air toward faces of occupants in the passenger compartment; a foot outlet provided on the downstream side of the heater as viewed along the flow of air for sending out air toward feet of the occupants in the passenger compartment; a target air-outlet temperature (TAO) calculating unit for calculating a target air-outlet temperature (TAO) for air sent out into the passenger compartment; and an outlet mode setting unit for setting at least a bilevel mode in which the face outlet and the foot outlet are opened at the same time and a foot mode in which the face outlet is closed, whereas the foot outlet is opened; the heater being adapted to adjust the heating capacity thereof directly on their own, and comprising further; a control unit configured to control operation of the heater such that the heating capacity of the heater for the target air-outlet temperature (TAO) during the bilevel mode operation becomes larger than the heating capacity of the heater for the target air-outlet temperature (TAO) during the foot mode operation. - View Dependent Claims (8)
