Is the fresh-keeping refrigerator an IQ tax? What is the main difference between it and an ordinary refrigerator?

I think the fresh-keeping refrigerators of big brands are not IQ taxes, but have certain technical content. Not long ago, my family changed to Rongsheng Ion Odor Purifier Series 609, and I experienced the excellence of fresh-keeping refrigerators instantly. The freshness-preserving function of your old refrigerator will be reduced to rubbish in seconds! Let me briefly introduce to you some of the differences between Rongsheng Ion Deodorizing Series 609 and ordinary refrigerators. First of all, the principle of keeping freshness in Rongsheng Ion Purifier Series 609 is to use moist natural wind + 360° ALL Around Cooling to make the cooling air inside the refrigerator more even, reduce the temperature difference in the cabin, and keep the food at the same temperature. In a more stable and balanced environment, coupled with the fully upgraded multi-channel micro-hole air supply, the cooling between shelves is more even, and it can also well replenish the humidity in the refrigerator, such as peaches, mangoes and other fruits. , if placed in an ordinary refrigerator, the skin will easily lose water and become wrinkled, but it has remained fresh and moist for several days in Rongsheng's refrigerator, and tastes the same as when it was first put in. Very good too. In addition, the Rongsheng Ion Purifier Series 609 not only has a great freshness-keeping function, but is also very energy-saving. It has reached the national first-class energy efficiency. After calculation, the electricity consumption per day is less than 1 kilowatt hour. There is no need to worry about the impact of a refrigerator of more than 600 liters on every day. The monthly electricity bill is a burden. Compared with my previous ordinary refrigerator, it not only allows the food to be stored longer, but also consumes less electricity. I recommend you check out the Rongsheng Ion Deodorizing Series 609 and do some homework. See if you like it!
