OVERCOOLED MEAT FRESH-PRESERVATION CONTROL METHOD, CONTROLLER, AND REFRIGERATOR

摘要

A control method for meat supercooling preservation, a controller and a refrigerator are provided. The control method comprises: S1 (101), acquiring a current temperature of meat in a compartment of a refrigerator in real time; S2 (102), determining whether the current temperature of the meat is greater than or equal to a first temperature threshold t0, and if yes, performing step S3 (103); S3 (103), controlling the compartment to perform a cooling operation; S4 (104), determining whether the meat has been cooled down to a phase transformation point temperature t1 during the cooling operation, and if yes, performing step S5 (105), the phase transformation point temperature t1 being the temperature of a critical point at which the phase transformation of the meat occurs; S5 (105), starting timing once the temperature has been cooled down to the phase transformation point temperature t1, and performing step S6 (106) after the timing reaches a first preset time period; and S6 (106), controlling the compartment to perform a low-temperature stable operation according to a third target temperature T3, the third target temperature T3being a freezing point temperature of the meat. The control method for meat supercooling preservation provided by the present disclosure may prolong the freshness-preservation period as much as possible while ensuring that the meat is not frozen.
