Equipped with a 32-bit ARM core chip and FOC control algorithm, it has a rapid temperature control response with an error of less than 1%, precisely scheduling the compressor and fan to ensure the refrigerator operates efficiently. Intelligent automatic defrosting management, precisely regulating the defrosting cycle to prevent ice accumulation on the evaporator, avoiding a decrease in cooling efficiency and an increase in energy consumption, and ensuring the stable operation of the refrigerator. Energy-saving and low-consumption optimization, intelligently adjusting the cooling cycle and compressor speed, with the Stop mode consuming power as low as microampere level, which complies with the national standards and saves electricity over the long term. Industrial-grade components are used, with 105℃ high-temperature resistant capacitors, suitable for various environments with a wide temperature range, and a low secondary repair rate, ensuring stability, durability, and outstanding cost performance. High-precision temperature control technology is linked with multiple sensors to achieve ±0.5℃ constant temperature control, reducing temperature fluctuations, extending the freshness period of food, and avoiding frosting and food spoilage.
