Title: VEHICULAR AIR-CONDITIONING SYSTEM
Abstract:
[Problem] To suppress the decrease in the comfort of occupants while suppressing the increase in the fuel consumption of an internal combustion engine in a vehicular air-conditioning system. [Solution] This vehicular air-conditioning system (1) is equipped with: an indoor air-conditioning unit (10); a seat air-conditioning unit (50); and a heating switching unit (115d) switching between seat heating operation and non seat heating operation. The vehicular air-conditioning system is also equipped with: a required heating value calculation unit (100a) that calculates a required heating value (Qr) of the internal combustion engine; and a necessary heating value determination unit (100b) that determines a necessary heating value (Qn) for the internal combustion engine which reflects the required heating value. Furthermore, the vehicular air-conditioning system is equipped with an operation control unit (100c) that controls the operation of the internal combustion engine so that the operating efficiency during the operation of the internal combustion engine decreases with an increase in the necessary heating value and increases with a decrease in the necessary heating value. The required heating value calculation unit is configured so as to reduce the required heating value during the seat heating operation relative to during the non seat heating operation.
