Abstract
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.
Claims11
A vehicle heat management system for a battery of a vehicle, the vehicle heat management system comprising:
- a refrigerant circuit including a compressor that compresses refrigerant in the refrigerant circuit a condenser that exchanges heat between circuits and an evaporator;
- a heating device, different from the refrigerant circuit that includes a heater that provides heat to liquid in the heating device and a heater core that warms air to be introduced into a passenger compartment of the vehicle by exchanging heat with liquid of the heating device, and that is coupled with the refrigerant circuit via the condenser;
- and a battery temperature regulation circuit that is coupled with the refrigerant circuit via a chiller to circulate the liquid that cooled by exchanging heat with the refrigerant circuit, and configured to be connected with the heating device to circulate the liquid circulating through the heating device into the battery temperature regulation circuit, wherein the heating device is configured to heat liquid, by the heater, warmed by exchanging heat, via the condenser, with the refrigerant compressed by the compressor in the refrigerant circuit when liquid in the heating device is not given enough heat from the refrigerant circuit, wherein air warmed by the heater core of the heating device is introduced into the passenger compartment of the vehicle, wherein the heating device is configured to warm liquid, in the battery temperature regulation circuit connected with the heating device, by exchanging heat, via the condenser, with the refrigerant compressed by the compressor in the refrigerant circuit, and wherein at extremely low temperatures, the refrigerant circuit stops, and the heating device circulates, in the battery temperature regulation circuit connected with the heating device, liquid heated by the heater.
