Description
technical field [0001] The invention relates to a three-door direct-cooling mechanical refrigerator and its refrigeration system, 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 different temperature requirements of users. The preservation temperature for fresh meat is -18 degrees Celsius, for fish and shrimp is 0 degrees Celsius, for cooked food is 8 degrees Celsius, for green leafy vegetables is 12 degrees Celsius, and for tropical fruits is 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 no more than 100L, and the operating time is short. Co...
