  "textContent": "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.",
