[0003] This type of fresh-keeping cabinet generally has air outlet at the top and return air at the bottom, and there is a cooling difference from top to bottom. Therefore, merchants will place some temperature-sensitive ingredients or drinks that need to be refrigerated quickly on the upper layer, and place some ingredients that do not require low temperatures on the lower layer. However, in actual application, the temperature zoning is not obvious enough. If the refrigeration power is too large, the ingredients below that do not need to be too low in temperature, such as some fruits and vegetables, will be frozen. If the refrigeration power is too small, the refrigeration speed of the drinks above will be slow, which cannot meet customer needs. The refrigerated fresh-keeping cabinets on the market with clear refrigeration zones use zoned refrigeration technology, which makes the overall cost too high and does not conform to the low-cost concept of commercial refrigerators.
