The multi-cycle refrigerator is similar to the "parallel" refrigeration system. The temperature of the refrigerator compartment and the freezer compartment can be arbitrarily adjusted or lowered according to the preference of the consumer. The temperature in the refrigerator can be freely set according to the needs of the consumer. It takes a few degrees to be a few degrees. In addition, it is impossible in any case to connect the refrigerator to the freezer compartment alone. The discrete multi-cycle technology makes it easy to achieve independent switching of refrigeration and freezing due to its independent refrigerating and freezing cycle, which is more energy efficient.
