Heat pump system for vehicle

A heat pump system for a vehicle comprising a refrigerant line for cooling or heating an interior of the vehicle by using a refrigerant discharged from a compressor,

• wherein the refrigerant line comprises:
• an outdoor condenser configured to condense the refrigerant by exchanging heat between the refrigerant and outdoor air;
• and
• an indoor heat exchanger arranged in an air conditioning case to exchange heat between the refrigerant discharged from the compressor and air, and
• wherein the refrigerant discharged from the compressor Selectively flows to the indoor heat exchanger or the outdoor condenser.

• an indoor heat exchanger arranged in an air conditioning case to exchange heat between the refrigerant discharged from the compressor and air;
• and
• a receiver dryer configured to separate and store gaseous refrigerant and liquid refrigerant,
• wherein the refrigerant flow is controlled such that in a cooling mode the receiver dryer is located downstream of the outdoor condenser in the refrigerant flow direction and in a heating mode the receiver dryer is located downstream of the indoor heat exchanger in the refrigerant flow direction.
