Abstract
A vehicular heat management system includes a refrigerant circulation line configured to generate hot energy or cold energy depending on a flow direction of a refrigerant, a heater core side coolant circulation line configured to transfer refrigerant heat generated in the refrigerant circulation line to a heater core to heat a passenger compartment, and a battery side coolant circulation line configured to receive coolant heat of the heater core side coolant circulation line via a coolant and then circulate the coolant through a battery to preheat the battery.
Claims13
A vehicular heat management system, comprising:
- a refrigerant circulation line configured to generate hot energy or cold energy depending on a flow direction of a refrigerant;
- a heater core side coolant circulation line configured to circulate a coolant through a heater core;
- a battery side coolant circulation line configured to circulate the coolant through a battery;
- a first heat exchanger configured to cause the refrigerant of the refrigerant circulation line and the coolant of the heater core side coolant circulation line to exchange heat with each other so that refrigerant heat generated in the refrigerant circulation line is transferred to the heater core side coolant circulation line;
- a second heat exchanger configured to cause the coolant of the heater core side coolant circulation line and the coolant of the battery side coolant circulation line to exchange heat with each other so that coolant heat of the heater core side coolant circulation line is transferred to the battery side coolant circulation line;
- and
- a third heat exchanger configured to cause the refrigerant of the refrigerant circulation line and the coolant of the battery side coolant circulation line to exchange heat with each other so that cold energy of the refrigerant generated in the refrigerant circulation line is transferred to the battery side coolant circulation line.
