Abstract:
A vehicle air conditioning apparatus is provided that can extend the mileage of a vehicle by reducing the power consumed by the operation of a compressor and a heater. When a required quantity of heating Q_req is acquired, the minimum power sharing ratio between quantity of heat release Q_hpof a water-refrigerant heat exchanger  22  and quantity of heat release Q_htrof a water heater  32  is calculated, which allows the power consumption W_total to be minimized, and a compressor  21  and the water heater  32  are operated based on the result of the calculation.

Claim (Index 1):
A vehicle air conditioning apparatus comprising:\n a compressor configured to compress and discharge refrigerant; a heat medium heating radiator configured to release heat from the refrigerant and heat the heat medium; an air cooling heat exchanger configured to absorb the heat into the refrigerant and to cool air blowing to a vehicle interior; an outdoor heat exchanger provided outside the vehicle interior and configured to release the heat from or absorb the heat into the refrigerant by performing a heat exchange between the refrigerant and outdoor air; a heat medium circuit configured to allow the heat medium heated by the heat medium heating radiator to flow through; an air heating radiator configured to release heat from the heat medium flowing through the heat medium circuit and to heat the air blowing to the vehicle interior; and a heat medium heater configured to be able to heat the heat medium flowing through the heat medium circuit by electric power, wherein: a heating operation is performed by releasing the heat from the refrigerant discharged from the compressor in the heat medium heating radiator and absorbing the heat into the refrigerant after the heat release in the outdoor heat exchanger; a heating and dehumidifying operation is performed by releasing the heat from the refrigerant discharged from the compressor in the heat medium heating radiator and absorbing the heat into the refrigerant after the heat release in the air cooling heat exchanger and the outdoor heat exchanger; and the heat medium heater can heat the heat medium flowing through the heat medium circuit, the vehicle air conditioning apparatus further comprising: a heat medium temperature estimating part configured to estimate a temperature of the heat medium that is heated by the heat medium heating radiator and flows through the heat medium circuit; an insufficient-quantity-of-heat calculation part configured to calculate an insufficient quantity of heat during one of the heating operation and the heating and dehumidifying operation, based on a result of an estimation by the heat medium temperature estimating part; and a heat medium heater control part configured to control the heat medium heater, based on the insufficient quantity of heat calculated by the insufficient-quantity-of-heat calculation part.
