Abstract
A vehicle heat management system includes a refrigerant circuit, a battery temperature regulation circuit, and an electric part cooling circuit. The refrigerant circuit circulates a refrigerant to regulate a temperature inside a passenger compartment through the refrigerant circuit. The battery temperature regulation circuit regulates a temperature of a battery by introducing a liquid that exchanges heat with the refrigerant to the battery. The electric part cooling circuit circulates a liquid cooled by a radiator circulates through the electric part cooling circuit, and is capable of cooling a first and second pieces for driving a vehicle. In a first mode, the liquid cooled by the radiator cools the first piece of equipment, the refrigerant of the refrigerant circuit cools the second piece of equipment, and the liquid which has exchanged heat with the refrigerant is introduced in parallel to the battery and the second piece of equipment.
