VEHICLE HEAT MANAGEMENT SYSTEM

A vehicle heat management system includes a refrigerant circuit, a heating circuit, and a battery temperature regulation circuit. The refrigerant circuit circulates a refrigerant to regulate a temperature inside a passenger compartment through the refrigerant circuit. The heating circuit circulates a liquid that exchanges heat with the refrigerant through the heating circuit. The heating circuit regulates the temperature inside the passenger compartment. The battery temperature regulation circuit regulates a temperature of a battery by introducing a liquid that exchanges heat with the refrigerant to the battery.
