The refrigerator mainboard is the control core of the entire machine, unifying and coordinating various components of the refrigerator to ensure all modules operate in an orderly manner. It organizes the overall operating logic of the machine, preventing conflicts that may arise from independent operation of different parts, ensuring the overall operation order of the refrigerator, and maintaining the basic working state of the equipment. Based on changes in the internal temperature data, the mainboard issues corresponding commands to control the compressor to start and stop. It adjusts the working state of the equipment according to the actual cooling needs of the compartment, preventing unnecessary compressor operation and matching the basic refrigeration cycle rhythm of the refrigerator. Taking into account the refrigerator's cooling conditions and the status of each temperature zone, the mainboard regulates the running speed of the internal and external fans. It balances the circulation of cold air inside the compartment, improves uneven temperature distribution in the refrigerator, and makes the internal temperature more uniform. Equipped with multiple fixed operation programs, it can adapt to different usage scenarios such as daily use, rapid cooling, and holiday mode. The device's operation state can be switched with one click, meeting the diversified storage needs of household food items.
