Abstract: A non-freezing meat fresh-preservation control method, a controller and a refrigerator are provided. The non-freezing meat fresh-preservation control method comprises: S1 (101), acquiring a current temperature of meat food in a compartment of a refrigerator in real time; S2 (102), judging whether the current temperature of the meat food is greater than or equal to a first temperature threshold t0, and if yes, performing S3 (103); S3 (103), controlling the compartment to perform a cooling operation; S4 (104), judging whether the meat food is frozen during the cooling operation, and if yes, performing S5 (105), S5 (105), controlling the compartment to perform a heating operation; and continuing the performance of the S1 (101) after the performance of the S5 (105) is completed. The non-freezing meat fresh-preservation control method provided by the present disclosure may prolong the fresh-preservation period as much as possible while ensuring that the meat food is not frozen.
