Supermarket commercial refrigeration has realized the advantages of double preservation, energy saving and power saving. Breakthrough
successfully explored the limits of energy saving and preservation technology, and made another attempt to continuously innovate the core technology of supermarket commercial refrigeration. Upgrading the discrete multi-circulation system, adopting independent refrigeration and circulation systems in commercial refrigeration refrigeration, freezing, greenhouse and other compartments, supermarket commercial refrigeration has achieved breakthroughs in the advantages of double preservation, energy saving and electricity saving. Nano water mist fresh-keeping technology keeps 85% of the optimal food storage humidity for a long time, which greatly extends the food fresh-keeping time.
refrigerant mainly exists in supermarket commercial refrigeration evaporator and condenser, a refrigeration equipment. Choosing a heat exchanger with a suitable structure can not only ensure the heat exchange effect of the system, achieve the best energy efficiency ratio, but also reduce the amount of working fluid as much as possible. Supermarket commercial refrigeration directly affects the demand for refrigerant production. There is basically no regulation on the charging amount or charging ratio in the norms and regulations at home and abroad, and the size of the refrigerant charging in supermarket commercial refrigeration. I think it should be on the agenda at least in China now. While formulating energy efficiency specifications for refrigeration and heat pump products, the maximum charging ratio limit of commercial refrigeration products in supermarkets should be formulated to promote various technologies that can reduce charging.
analyzed the unit refrigeration charge value, supermarket commercial refrigeration system sample using different evaporators. The statistical value of the filling ratio is arranged as a flooded evaporator > falling film evaporator > plate evaporator > dry evaporator. It is recommended to use plate heat exchangers in supermarket commercial refrigeration systems less than 300 kilowatts; in refrigeration (heat pump) equipment greater than 300 kilowatts, the full-liquid evaporator has the largest refrigerant charge, and it is recommended to use a smaller one. The membrane supermarket commercial refrigeration evaporator replaces the flooded evaporator, and the dry evaporator technology should be studied and perfected.
see the current supermarket commercial refrigeration market, various product types are different, Italian, French, Japanese, multi-door, side-by-side … … compressor is the heart of commercial refrigeration, the upgrade of the heart is supermarket commercial refrigeration The premise of the whole machine upgrade, relying on the global integration advantages, refrigerated showcase has strategic cooperation with well-known domestic compressor manufacturers such as Huayi, Jiasi Bella, etc., using its exclusive high-efficiency compressors for refrigerated showcase, and it is truly realized Improve the energy efficiency of the whole machine.
