Abstract
A heat pump system for a vehicle may control a temperature of a battery module by using one chiller in which a refrigerant and a coolant are heat-exchanged, and may increase a flow rate of the refrigerant by applying a gas injection device that selectively operates in a heating or dehumidifying mode of a vehicle, thereby maximizing heating performance.
Claims19
A heat pump system for a vehicle, comprising:
- an air conditioner circulating a refrigerant through a refrigerant line;
- a coolant circulation apparatus circulating a coolant through a coolant line;
- a chiller connected to the coolant circulation apparatus through the coolant line, the chiller being connected to the refrigerant line through a refrigerant connection line, and the chiller configured to heat-exchange a selectively introduced coolant with a refrigerant supplied from the air conditioner to control a temperature of the coolant;
- and
- a gas injection device provided in the air conditioner and increasing a flow rate of the refrigerant circulating in the refrigerant line by bypassing a portion of the refrigerant passing through an internal condenser to a compressor,
- wherein a heat-exchanger provided in the air conditioner is connected to the coolant circulation apparatus through the coolant line so that the coolant is supplied from the coolant circulation apparatus.
