Cooling control method for refrigerator

A cooling control method for a refrigerator, wherein the refrigerator comprises:

• a refrigerator body in which a refrigerator compartment and at least one freezer compartment arranged below the refrigerator compartment are defined;
• a door body arranged on the front side of the refrigerator body for a user to open or close the refrigerator compartment and the at least one freezer compartment;
• a refrigeration system comprising a compressor and configured to supply cold capacity to the refrigerator compartment and the at least one freezer compartment;
• a branch air supply device comprising a fan and provided with a refrigerating air outlet which is in controlled communication with the refrigerator compartment and a freezing air outlet which is in controlled communication with the at least one freezer compartment, so as to supply the cold capacity supplied by the refrigeration system into the refrigerator compartment and/or the at least one freezer compartment in a controlled manner;
• and the cooling control method comprises the following steps:
• measuring an actual temperature of the at least one freezer compartment, and setting a freezing parameter of the at least one freezer compartment according to the actual temperature of the at least one freezer compartment;
• when the actual temperature of the at least one freezer compartment is higher than a preset freezing startup temperature, measuring an actual temperature of the refrigerator compartment, and setting a refrigerating parameter of the refrigerator compartment according to the actual temperature of the refrigerator compartment;
• when the actual temperature of the refrigerator compartment is higher than a preset refrigerating startup temperature, and a difference value between the actual temperature of the at least one freezer compartment and the preset freezing startup temperature is higher than a first preset threshold, resetting the refrigerating parameter and the freezing parameter, wherein the refrigerating parameter and the freezing parameter each include a first parameter, a second parameter and a third parameter;
• and
• operating, according to a set of the refrigerating parameter and the freezing parameter, the compressor, the fan and the branch air supply device in a preset state corresponding to the set.
