Difference between Full Surrounding Air Flow and Double Circulation in Samsung Refrigerator

Thank you for your interest in Samsung products! The difference between single-cycle refrigeration and double-cycle refrigeration of Samsung refrigerator is as follows:

Single cycle refrigeration: the refrigeration system has only one evaporator, which drives the refrigerator and freezer to refrigerate. When the refrigerator is running, two boxes are cooled at the same time. The temperature of this refrigerator is generally controlled by the thermostat or temperature sensor of the refrigerating room, and the freezing temperature cannot be adjusted independently.

Double-cycle refrigeration: The refrigeration system has two evaporators, which are respectively installed in the cold storage room and the freezing room. The flow direction of the refrigeration liquid is controlled by electromagnetic valves to achieve the effect of independent refrigeration in the cold storage room and the freezing room. The temperature of the refrigerating chamber and freezing chamber of this refrigerator can be controlled independently, thus reducing the refrigeration area, making the refrigerator more energy-saving and stronger in refrigeration capacity.
