Rong Sheng refrigerator:
Rong Sheng has always been the benchmark of the refrigerator industry, guiding the continuous upgrading of the technical level of the refrigerator industry in China. Twenty-five years ago, Rong Sheng successfully developed the first household refrigerator with two doors and two temperature zones in China. In 200 1 year, Rong Sheng Refrigerator launched a super energy-saving refrigerator, with a daily power consumption of only 0.48 kWh, setting a record for the lowest power consumption in the industry. In 2003, Rong Sheng won the exclusive bid for the "United Nations Energy Saving Star Refrigerator Award" jointly established by the United Nations GEF and the State Environmental Protection Administration with a minimum daily power consumption of 0.42 kWh. Since then, through continuous technological innovation, new breakthroughs have been made in energy-saving level. The second, third and fourth generation "Energy-saving Star" series refrigerators have been listed one after another, and the power consumption has also dropped from 0.42 degrees to 0.35 degrees, 0.33 degrees, 0.28 degrees and 0.25 degrees, which has always maintained the leading position in the global refrigerator energy-saving technology level. Over the past 25 years, Rong Sheng refrigerator has persisted in the accumulation of innovative technology and has been leading China refrigerator. Rong Sheng's three-door, multi-door, opposite-door and other high-end refrigerators combine many leading technologies at home and abroad, including the invention patent "discrete multi-cycle technology", colorful photosynthetic fresh-keeping technology, double refrigeration and double-cycle technology, and Vc fresh-keeping magic treasure. It is a master of preservation technology and is called "original ecological preservation refrigerator". A fresh-keeping experiment conducted by the College of Food Science of South China Agricultural University also showed that the fresh-keeping effect of the original ecological refrigerator in Rong Sheng was several times higher than that of ordinary refrigerators.
Omar refrigerator:
Based on the evaporator in the freezer, a freezer evaporator is added, and the added freezer evaporator is arranged on the surface around the inner cavity of the freezer. The refrigerant coming out of the capillary tube first passes through the evaporator inside the freezer, then flows through the evaporator around the freezer, and then reaches the freezer evaporator. When the refrigerator is turned on, there are evaporators inside and around the freezing chamber, and a three-dimensional cold air curtain is formed inside the freezing chamber, so the refrigeration is faster and stronger. When the refrigerator is turned off, the temperature of the evaporator around the freezing chamber is below -30℃, which can absorb the heat from the insulation layer. When the refrigerator is turned on again for refrigeration, it will quickly take away the heat absorbed by the evaporator around the freezing chamber, so the start-stop time ratio is reasonably designed (the temperature of the heat transfer plate in the evaporator around the freezing chamber will rise to-when the refrigerator stops). The invention meets the requirements of refrigeration and heat preservation at the same time, and the low cost is more conducive to energy saving of the refrigerator, and the temperature of the freezing chamber is more uniform, which is more conducive to food preservation.
