Problems solved by technology

[0010] In addition, in this patent publication, only a cooling system with a multi-stage compressor and a refrigerant cycle for a freezer at -40 to -20°C and a freezer at -15 to 5°C is disclosed
However, there is no disclosure concerning the 3-stage cooling system of the present invention using a quick-freezing chamber at -40 to -30°C, a freezing chamber at -20 to -15°C and a refrigerating chamber at 0 to 5°C
Naturally, nothing is disclosed about the supply, circulation and / or recovery of the refrigerant to maximize thermal efficiency, e.g. transfer, absorption and / or discharge of thermal energy from the refrigerant

Embodiment Construction

[0038] The present invention relates to a three-stage cooling and energy-saving defrosting system using a quick-freezing chamber at -40 to -30°C, a freezing chamber at -20 to -15°C, and a refrigerating chamber at 0 to 5°C. The system includes the following three stages Cooling step: 1) The quick-freezing step at -40 to -30°C in the quick-freezing chamber, in which the liquid-phase refrigerant ejected from the electronic valve (S3) far away from the condenser after two-stage compression is evaporated, and then the ultra-low temperature liquid phase The refrigerant is further evaporated in sequence until the quick-freezing chamber is lower than -40°C; 2) The freezing step of -20 to -15°C in the freezing chamber, wherein the electronic valve (V1) is closed after the electronic valve (V1) is recovered from the quick-freezing chamber. The refrigerant injected by the valve (R1) evaporates, and can further evaporate the liquid-phase refrigerant ejected from the electronic valve (S2) f...
