The product is a refrigerator with unique bio-fresh compartment and energy-saving design. The bio-fresh compartment maintains a temperature close to 0°C and maximum humidity through the three-circulation refrigerating system, cool air circulation system, and moisture control device. This controlled environment effectively suppresses the growth and reproduction of microorganisms (bacteria, yeast, and molds), allowing food to stay fresh two to three times longer than under conventional conditions. The energy-saving design features a high energy-saving compressor and three-circulation refrigerating system for improved refrigerating efficiency and energy-saving benefits.
