Abstract
A vehicle includes an engine, an engine cooling system configured to cool the engine with a coolant, an air conditioning apparatus, a heat exchanger that exchanges heat between the coolant and a refrigerant, and an ECU that controls the air conditioning apparatus. The air conditioning apparatus includes a compressor that compresses the refrigerant, and the compressor is driven in response to an air conditioning request to air condition a passenger compartment. Even in the absence of the air conditioning request, the ECU causes the compressor to be driven to heat the coolant by radiation of heat from the refrigerant.
