The refrigerator single circulation system with only two temperature areas of the refrigerating chamber and the freezing chamber can be realized.

Refrigerators with variable temperature zones are generally three-cycle systems, and the three-temperature zone refrigerators described above are difficult to realize with a single cycle system. This is because the evaporator in the existing single circulation system is arranged at the lower position of the box body, if the temperature change chamber is at the lower left or lower right part, the temperature change chamber is near the evaporator, because the evaporator can continuously work for a period of time to provide cold energy for three chambers, and the temperature change chamber is difficult to realize the function of the refrigerating chamber due to the influence of cold energy conduction of the evaporator.

And the three-cycle refrigeration system comprises a refrigerating chamber, a temperature-changing chamber and a freezing chamber which are respectively provided with an evaporator, and the evaporators corresponding to the set temperature of each chamber stop working. In this way, the three-temperature-zone refrigerator can be realized, but the three-cycle refrigeration system also has many disadvantages, such as complex control program, complex refrigeration system, significant cost increase, and the like.

The sterilization function of the refrigerator sold in the market at present is generally in a refrigerating chamber, and bacteria and viruses are generally considered to survive only at a higher temperature in the past, such as the temperature of a freezing chamber is below minus 18 ℃, and the low temperature is not beneficial to the survival of the bacteria and the viruses. However, since the emergence of new crown epidemic situation, new crown virus is detected by the cold chain food outer package imported from many places, which lets people know that: the virus remains viable at low temperatures, which also subverts the previously ubiquitous idea. Therefore, it becomes necessary to provide a sterilization apparatus in the temperature-variable chamber.
