An LG fridge with DoorCooling cools faster and more energy-efficiently compared to a fridge with a normal cooling system. A cold airflow keeps the temperature consistent and prevents warm air from entering the fridge. LG DoorCooling distributes this cold air throughout the entire fridge. This way, your products are evenly cold everywhere. With LG DoorCooling fridges, your food stays fresh longer and you lose less energy when you open the door.
