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 the 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 the 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 for controlling the operation of the heating source;
wherein the control unit controls the 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 an 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 the 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 the 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 for controlling the operation of the heating source;
whereinthe control unit controls the 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)
