the primary condenser 20 is used for condensing the gas discharged by the compressor 10;
the gas-liquid separator 30 is used for performing gas-liquid separation on condensed substances discharged by the primary condenser 20, so that liquid refrigerant enters the refrigeration evaporator assembly 50, and gaseous refrigerant enters the secondary condenser 40;

the refrigerating evaporator assembly 50 is used for exchanging heat with air in a refrigerating chamber to evaporate the refrigerant discharged by the gas-liquid separator 30 into refrigerating gas;
the freezing evaporator assembly 60 is configured to exchange heat with air in the freezing chamber, so that the refrigerant discharged from the secondary condenser 40 is evaporated into a freezing refrigerant gas.
Specifically, the compressor 10 exhausts air and then passes through the first-stage condenser 20, most of the refrigerant with higher boiling point in the mixed working medium in the gas-liquid separator 30 is in a liquid state, most of the refrigerant with lower boiling point is in a gaseous state, one path of the refrigerant with high boiling point in the liquid state passes through the refrigeration evaporator assembly 50, returns to the mixing cavity in the compressor 10 through the air return pipe, enters the second-stage cylinder, and is discharged out of the compressor 10; one path of the gaseous low-boiling point refrigerant enters the primary cylinder 11 of the compressor 10 through the secondary condenser 40 and the freezing evaporator assembly 60, is discharged into the mixing chamber 13 through the primary cylinder 11, is mixed with the refrigeration path intake air, and is discharged into the primary condenser 20 through the secondary cylinder 12. In the whole cycle, the high-temperature refrigeration area is mainly refrigerated by a high-temperature refrigerant, the system efficiency is high, meanwhile, the heat exchange temperature difference is small, the irreversible loss is small, and the overall efficiency of the refrigeration system is high. Meanwhile, most of low-boiling-point cryogenic refrigerant enters the freezing chamber, so that the rapid freezing of the freezing chamber is realized, and the cryogenic function is realized. In addition, refrigeration and freezing are simultaneously carried out, so that the influence of the back rise of the refrigeration and freezing temperature of the existing series-parallel system is avoided, and the temperature fluctuation is greatly reduced.
Alternatively, the gas-liquid separator 30 may employ a separation method including at least one of gravity settling, baffling separation, centrifugal force separation, wire mesh separation, ultrafiltration separation, and packing separation.

Specifically, the refrigeration regenerator 51 combines (winds) the refrigeration capillary tube and the suction pipe of the compressor 10 together to perform heat exchange sufficiently, and the refrigeration regenerator 51 can fully evaporate the residual liquid refrigerant from the refrigeration evaporator body 52 in the suction pipe of the compressor 10 in addition to liquefying more liquid refrigerant in the refrigeration capillary tube, so as to prevent the liquid refrigerant from returning to the compressor 10 and causing liquid impact.
Optionally, the freeze evaporator assembly 60 comprises a freeze evaporator body 62 and a freeze regenerator 61, wherein,
the first air inlet of the freezing heat regenerator 61 is connected with the secondary condenser 40, the first air outlet of the freezing heat regenerator 61 is connected with the air inlet of the freezing evaporator body 62, and the air outlet of the freezing evaporator body 62 is connected with the second air inlet of the freezing heat regenerator 61; and a second air outlet of the freezing heat regenerator 61 is connected with the primary cylinder 11.

When the refrigerating and freezing compartments need to be cooled, the compressor 10 operates to cool the refrigerating and freezing compartments at the same time, and each compartment is provided with a temperature sensor for detecting the temperature in the compartment. When the temperature of one of the chambers reaches the set temperature stop point and the other chamber needs to refrigerate, the fan of the chamber stops working, the evaporating temperature of the evaporator can be sharply reduced due to the stop of the fan, the pressure in the mixing cavity can be reduced, the flow of the other path of refrigerant is increased, the evaporating temperature is reduced, the refrigerating chamber is quickly cooled, the stop point is quickly reached, and the compressor stops working at the moment.
