Abstract: A heat pump system for a vehicle is capable of performing cooling or heating of a vehicle interior by using a natural refrigerant in compliance with environmental regulations, and by efficiently adjusting the temperature of the battery module by using a single chiller where a refrigerant and a coolant heat-exchange each other. The heat pump system is capable of maximizing the cooling and heating performance by operating in the supercritical cycle, in which the pressure and temperature of the refrigerant is higher than a critical pressure and temperature, by applying R744 refrigerant, which is a natural refrigerant utilizing carbon dioxide.

Abstract: A heat pump system for a vehicle is provided so that the thermal energy generated from the refrigerant when condensing and evaporating the refrigerant is selectively heat-exchanged with the coolant. The vehicle interior temperature is adjusted by using the heat-exchanged low-temperature or high-temperature coolant. The heating efficiency of the vehicle is improved by selectively using the ambient air heat, the waste heat of the electrical component, and the waste heat of the battery module at the time of heating the vehicle interior. The heating efficiency of the vehicle is further improved by increasing the overall travel distance of the vehicle by efficiently adjusting the temperature of the battery module so that the optimal performance of the battery module may be achieved.
