4 changes in the world of refrigerators: fluoride-free, frost-free, seamless, full-space freshness

       American accountant McKinsey once said that time is the soil of all achievements in the world. Following the trajectory of refrigerator development, the world’s refrigerator industry has undergone four major changes over the decades. From fluoride-free refrigerators, frost-free refrigerators, seamless refrigerators, to the four changes of all-space freshness refrigerators, each major technological innovation has opened up a new era of healthier, high-end freshness storage for people.
　　As a product closely related to food and drink, a good refrigerator’s first task is to be healthy, and to this end, the industry has been exploring forward for many years. In 1931, R-12 Freon was discovered and this refrigerant has been used by the industry for more than 50 years since then, however, in the 1970s and 1980s, it was discovered that Freon leaks could cause a chemical reaction with ozone, leading to a reduction in the amount of ozone and threatening human health, so the search for a safe and harmless refrigerant was on. Research and development of new technology was imminent.
　　In 1993, Haier refrigerators put an end to this by bringing China’s first super fluoride-free energy-saving refrigerator through its original fluoride-free technology. The following year, its super energy-efficient fluoride-free refrigerator appeared at the World Earth Day Exhibition in the USA, becoming the only environmentally friendly product from a developing country. Data provided by the US EPA showed that the refrigerator’s potential to damage the ozone layer had been reduced by 87%; energy efficiency would rise to over 50%.
　　Haier refrigerators continued to promote fluoride-free in the following years, achieving fluoride-free production of the entire refrigerator system in 1997 and becoming the first Chinese company to achieve fluoride-free replacement of the entire line. At the same time, its research and achievements in fluoride-free and energy-saving technologies were also at the forefront of the world, with electricity consumption increasing from 0.8 degrees/day to 0.68 degrees/day, exceeding the European A-class energy consumption standard.
　　From frost refrigerators to frost-free refrigerators, technology to change people’s fresh storage life after solving the problem of refrigerant to achieve fluoride-free, people’s focus on refrigerator innovation began to shift to the ingredients storage itself, promoting the evolution and iteration of preservation technology. From the early days of refrigerators, the popular refrigerators on the market at that time generally used direct cooling. However, this resulted in a thick layer of frost in the freezer, which had to be removed manually on a regular basis, making it quite cumbersome. Due to uneven refrigeration, it was not uncommon for ingredients to be frozen in some places and not in others, which was not ideal for freshness.
　　User demand is the vane of the market. After continuous innovation, the industry launched the main frost-free air-cooled refrigerator, however, due to the limitations of the technology, the market products only to achieve a slight frost or part of the frost-free. And, air-cooled technology is mostly used in high-end products, has not been able to get a wide range of popular. Until 2010, Haier refrigerator launched the first three-door frost-free refrigerator, the industry into the “full frost-free era”. Since then, Haier refrigerator first full frost-free technology for the whole series of applications, to promote the gradual popularization of air-cooled refrigerators. Today, the market share of this category has reached 96.1%, becoming the absolute mainstream of the market. Since then, users have also said goodbye to the tedium of manual defrosting and entered a new era of more convenient and efficient fresh storage.
　　As economies around the world continue to progress, people’s income levels are also growing. From the data of the past 20 years, the per capita income of the United States rose from 15,000 yuan to 27,000 yuan, an increase of 80%, and the per capita income of China rose from 800 yuan to 5,600 yuan, an increase of 600%. Under this trend, the consumer side of home appliances also shows a trend of high-end.
　　As a result, built-in products become the future wind. Embedded refrigerator will refrigerator and cabinet between the retention of heat dissipation spacing from 10CM shrink to 2CM. after that, in order to completely realize zero embedded, even flat embedded, after and because of the bottom front heat dissipation technology, centrifugal variable track hinge technology research and development, solve the refrigerator both sides need to stay with heat dissipation spacing, embedded in the cabinet after the refrigerator door body can not be fully open and other problems. On this basis, the improvement of foaming technology and bottom cooling technology compressed the thickness of the box to 60cm, matching the standard depth of the global cabinet market, realising a pure flat and seamless home integration experience, which also marked the user experience officially into the “seamless era”.
        As the traditional refrigerator freezer area can not accurately control moisture, ingredients do not add distinction to the storage makes the freshness period is short, rapid loss of nutrients, fruits and vegetables, such as a few days to wilt, spoilage and other situations frequently. To this end, the industry focused on the attack, the introduction of a series of new technologies. Among them, the whole space preservation technology, to do the dry and wet storage, so that the freezer area dry area humidity for 45%, wet area humidity for 90%, for different ingredients to provide differentiated storage environment, to achieve long-term storage of fruits and vegetables do not change colour, dry goods do not return to moisture health storage effect.
　　Review the refrigerator industry in recent decades, refrigerator step by step, in each node adhere to the user-centric, with a constant stream of new technology, subverting one after another traditional, for the user healthy diet life continued to inject new momentum.
