  • HEAT PUMP SYSTEM FOR A VEHICLE
    Publication number: 20250313063
    Abstract: A heat pump system for a vehicle may be capable of performing cooling or heating of an interior of the vehicle by using a natural refrigerant and efficiently adjusting the temperature of a battery module by using one chiller where a refrigerant and a coolant exchange heat. The system includes an air conditioner unit with a compressor, a first heat-exchanger, a second heat-exchanger, a first expansion valve, and a third heat-exchanger that are connected through the refrigerant line to circulate a refrigerant through the refrigerant line. The system also includes a chiller connected to the refrigerant line through the first connection 10 line. The chiller is configured to adjust a temperature of a coolant by heat-exchanging the coolant with the refrigerant supplied from the air conditioner unit.
