Abstract
A heat pump system for a vehicle may include a compressor, a first condenser, a receiver dryer, a second condenser, a first expansion valve, an evaporator, a first refrigerant connection line, a chiller, a second expansion valve, and a gas injection device. The flow of the refrigerant is controlled based on at least one mode for a temperature adjustment of a vehicle interior or for a temperature adjustment of a battery module. As a result, the heat pump system is capable of cooling or heating a vehicle interior by using a high-temperature coolant and a low-temperature coolant. Additionally, the heat pump system is capable of improving a heating performance by employing a gas injection device selectively operating at the time of cooling or heating a vehicle interior to increase the flow amount of the refrigerant.
