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 exchangerand quantity of heat release Q_htrof a water heateris calculated, which allows the power consumption W_total to be minimized, and a compressorand the water heaterare operated based on the result of the calculation.
