There are air outlets under the cooling zone in the fridge, which is called AirFALL Cooling technology. AirFALL Cooling can cool the food items of the door bins. At the same time, when the food on the shelf blocks the back air outlets, the air flow of AirFALL Cooling will increase, which can maintain the stable circulation of the cooling air of the refrigerator compartments. All of these lead to Natural Encircle Ai-Flow so as to make evener and more stable internal temperature, and keep food fresh longer.
