What does it mean to keep the refrigerator fresh at constant temperature?

Patented preservation technology. Refrigerator constant temperature preservation usually refers to the patented preservation technology of refrigerators in Rong Sheng. Preservation means that there are three kinds of fresh-keeping lamps in the vegetable room. Red light, blue light and yellow light synthesize colorful light with specific intensity and flicker frequency in the refrigerator, simulating sunlight to irradiate fruits and vegetables. Colorful light is closest to sunlight and has the best preservation effect, which allows fruits and vegetables to continuously synthesize nutrients through photosynthesis to achieve the preservation effect.
