The first refrigerating system is used for providing cold energy for the second refrigerating system to cool a refrigerant in the second refrigerating system, so that the second refrigerating system can reduce the cryogenic compartment to below minus 45 ℃. In general, the first refrigeration system includes a first compressor, a first condenser, a first pressure reducing member, a first evaporator, and a first return pipe connected end to end in sequence, so that a first refrigerant in the first refrigeration system circulates along the following paths: first compressor → first condenser → first pressure reducing member → first evaporator → first return pipe → first compressor.

The low-temperature and high-pressure refrigerant flows to at least one of the refrigerating capillary tube 7161, the freezing capillary tube 7162 and the auxiliary capillary tube 7163 by the reversing valve 715. The refrigerant flowing through the refrigerant storage capillary 7161 is reduced in pressure, expanded, and changed to a low-temperature and low-pressure state. The refrigerant of low temperature and low pressure absorbs heat in the refrigerating evaporator 7171 to become a state of high temperature and low pressure, and thus cools the refrigerating compartment of the refrigerating apparatus. The refrigerant flowing through the refrigerant capillary 7162 is reduced in pressure and expanded to a low-temperature and low-pressure state. The refrigerant of low temperature and low pressure absorbs heat in the freezing evaporator 7172 to become a state of high temperature and low pressure, and thus cools the freezing chamber of the refrigeration apparatus. The refrigerant flowing through the auxiliary capillary 7163 is reduced in pressure, expanded, and changed to a low-temperature and low-pressure state. The low-temperature and low-pressure refrigerant absorbs heat in the auxiliary evaporator 7173 to become a high-temperature and low-pressure state, and thus cools the cryogenic compartment of the refrigeration apparatus. Finally, the high-temperature low-pressure gas refrigerant is compressed again into a high-temperature high-pressure state while passing through the first compressor 711.

It should be noted that the above states of the refrigerant, i.e., the high temperature, the low temperature, the high pressure, and the low pressure of the refrigerant, are states after the refrigerant enters the corresponding component or flows out of the corresponding component, compared to states before the refrigerant flows into the corresponding component.

The second refrigeration system 720 operates as follows:

the refrigerant flowing out of the second compressor 721 is in a high-temperature and high-pressure state, is cooled while passing through the second condenser 722, and is in a low-temperature and high-pressure state. When the low-temperature and high-pressure refrigerant flows through the second depressurizing means 724, the pressure is reduced and expanded, and the refrigerant is changed to a low-temperature and low-pressure state. The low-temperature and low-pressure refrigerant absorbs heat in the second evaporator 725 to become a high-temperature and low-pressure state, and thus cools the cryogenic compartment of the refrigeration apparatus. The high-temperature low-pressure gas refrigerant is compressed into a high-temperature high-pressure state again when flowing through the second compressor 721.
