Abstract
When front and rear air conditioning units perform dehumidification heating operation, and when a battery is to be cooled, a refrigeration cycle circuit performs cooling operation and supplies a liquid-phase refrigerant to front and rear evaporators and a battery cooling heat exchanger. A heating circuit supplies a high temperature liquid heated by an electric heater to front and rear heater cores. Air cooled by the front and rear evaporators is warmed by the front and rear heater cores and supplied to a passenger compartment. A battery cooling liquid cooled by the battery cooling heat exchanger is delivered to the battery and cools the battery.
