Thanks to CTOnews.com netizens Fat Cat, for the clue delivery! CTOnews.com, January 17, according to the official news of Xinfei Electric Appliance, the research and development team of Xinfei has developed the world's first air-cooled ultra-low-temperature refrigerator, achieving a refrigeration temperature breakthrough of-120 ℃.

According to reports, with the development of biopharmaceutical, biomedical and life sciences and the improvement of people's living standards, the market demand for cryogenic refrigerators is showing a trend of vigorous development. At present, the cryogenic refrigeration products sold in the market are based on cascade steam compression refrigeration technology or non-azeotropic mixed refrigerant throttle refrigeration technology. Due to technical defects such as import of key components and materials, non-environmental protection of refrigerants, complex system and so on, it is difficult to exceed-80 ℃ no matter which refrigeration technology is adopted.

At the beginning of 2020, Xinfei R & D team gave full play to its advantages in the product design of new refrigeration technologies and joined forces with Xi'an Jiaotong University to set up a new refrigeration equipment technology research institute to carry out research and development of ultra-low temperature refrigerators based on inverse Brayton air refrigeration technology.

This technology carries out reverse Brayton cycle refrigeration through high-speed turbine, adhering to the concept of energy saving and environmental protection, and uses natural working fluid (air, nitrogen, etc.) as a non-phase change refrigeration cycle, successfully breaking the refrigeration temperature below-120 ℃. The research and development of cryogenic refrigerator lasted three years, from scratch, from recognition to application, from the design of each drawing to the manufacture of each part, tackling many technical problems, and completed the research and development process of-86 ℃ and-120 ℃ cryogenic project from principle verification, test prototype to product prototype.

The cryogenic refrigeration products developed by ▲ Tuyuan Xinfei cryogenic project can meet the market demand for cryogenic environment in the fields of medical treatment, military industry, scientific research institutions and laboratories. With the rapid growth of special storage needs such as vaccines, personal cord blood storage and plasma storage, the market will become larger and larger, and each region will become large-scale.

CTOnews.com learned that after the development of the cryogenic project, Xinfei will build the world's first air refrigeration cryogenic refrigerator production line, becoming the first global leading cryogenic product manufacturer with core technology and manufacturing capabilities of air refrigeration core components.
