The invention discloses a three-door direct cooling mechanical refrigerator and a refrigeration system thereof. The refrigeration system comprises a compressor, a condenser, a capillary, first, second and third electromagnetic valves, a freezing chamber evaporator, first and second freshness keeping chamber evaporators, a refrigerating chamber evaporator, and a one-way valve; the inlet of the condenser is connected with the outlet of the compressor; the inlet of the capillary is connected with the outlet of the condenser; each electromagnetic valve is provided with first, second and third openings; the first opening of the first electromagnetic valve is connected with the outlet of the capillary; the second freshness keeping chamber evaporator is connected between the second opening of the first electromagnetic valve and the inlet of the one-way valve; the inlet of the freezing chamber evaporator is connected with the third opening of the first electromagnetic valve; the outlet of the freezing chamber evaporator is connected with the inlet of the first freshness keeping chamber evaporator; the outlet of the freshness keeping chamber evaporator is connected with the third opening of the second electromagnetic valve; and the refrigerating chamber evaporator is connected between the first opening of the second electromagnetic valve and the third opening of the third electromagnetic valve.
Description
technical field [0001] The invention relates to a three-door direct-cooling mechanical refrigerator and a refrigeration system thereof, in particular to a refrigeration system for a three-door direct-cooling mechanical refrigerator with quick-freezing capability and a three-door direct-cooling mechanical refrigerator with the refrigeration system refrigerator. Background technique [0002] The three-door direct-cooling mechanical refrigerator can meet the different temperature requirements of users. The preservation temperature of fresh meat is -18 degrees Celsius, fish and shrimp is 0 degrees Celsius, cooked food is 8 degrees Celsius, green leafy vegetables is 12 degrees Celsius, and tropical fruits are 10 degrees Celsius. Celsius, so it is loved by users. However, at present, ordinary three-door direct-cooling mechanical refrigerators have no quick-freezing function, and the freezing space is small, generally not exceeding 100L, and in addition, the running time is short....
