Energy-saving operation: By coordinating the working rhythm of components such as compressors and fans, the motherboard helps optimize the overall machine's operating efficiency. While meeting cooling demands, it may also play a certain positive role in controlling power consumption. Multiple safety protections: Circuit designs often include over-voltage and over-current protection mechanisms. When an abnormal situation is detected, the motherboard may initiate a protection program, helping to reduce the risk of component damage caused by accidents. Low-noise operation support: By controlling the speed of the variable frequency compressor and the operation of the fan, the motherboard helps make the refrigerator run relatively quietly. Stable and durable design: motherboards typically use industrial-grade electronic components and are treated with surface protection. This helps improve their resistance to voltage fluctuations and humidity, aiming to provide long-lasting and stable performance.
