A detector detects a remaining power of a battery. A calculator calculates a demand load of air-conditioning based on at least one of a preset temperature set for air in a passenger compartment of an electric vehicle and an outside temperature of air outside of the electric vehicle. A switching portion switches a mode of air-conditioning between a battery mode and an engine mode based on the calculated demand load and the detected remaining power of the battery. The battery mode causes the battery to supply electric power for air-conditioning, and the engine mode causes an engine of the electric vehicle to supply combustion energy for air-conditioning.

A controller reduces a rotational speed of a Rankine cycle from a predetermined normal rotational speed during an operation of a compressor in a predetermined state when the controller determines that a predicted refrigerant flow quantity, which is predicted by assuming that the compressor is operated in a sole operation of the Rankine cycle at the predetermined normal rotational speed of the Rankine cycle, exceeds a predetermined flow quantity. The predetermined state is a state that satisfies a predetermined condition, which relates to the sole operation of the Rankine cycle.
