Abstract

The invention provides an I-type double-circulation refrigeration control method for a variable-frequency refrigerator. A double-circulation refrigeration system of the variable-frequency refrigerator is subjected to refrigeration control through a single-chamber refrigeration operation module and a double-chamber double-circulation operation module; the double-circulation refrigeration system of the variable-frequency refrigerator comprises a variable-frequency compressor, a dew removal pipe, a condenser, a filter, an air return pipe, a liquid storage device, an electromagnetic valve, two refrigeration branches, a controller and two refrigeration chambers; each of the two refrigeration branches comprises a capillary tube and an evaporator, and the two evaporators are respectively arranged in the two refrigeration chambers; when only one refrigeration chamber has the refrigeration requirement, the single-chamber refrigeration operation module is operated; and when the two refrigeration chambers both have refrigeration requirements, the double-chamber double-circulation operation module is operated. Balanced cooling of the two refrigeration chambers can be effectively guaranteed, the condition that one certain refrigeration chamber is too cold or too hot is avoided, and the method is more suitable for two refrigeration chambers with similar capacity, temperature and size, such as wine cabinets and cigar cabinets and other products with high precision requirements.
