What is ultra-low temperature refrigeration?

Ultra-low temperature refrigeration is a technology that improves the performance of a substance by lowering its temperature. It can cool the temperature of a substance to tens of degrees below zero or even lower, reaching the temperature that can be shown in the current temperature table, below -273.15℃ (zero degrees). The physical principle of ultra-low temperature refrigeration is to transfer it from a low temperature environment to a high temperature environment by compressing the refrigerant, and then compressing and expanding the refrigerant to achieve the cooling of the low-temperature object.

Ultra-low temperature refrigeration technology is mainly used in the following fields:

Ultra-low temperature refrigeration is widely used to preserve biological samples, drugs, vaccines, cells, etc. It can inhibit biological activity and effectively slow down the metabolic reaction of organisms.

Ultra-low temperature refrigeration is also widely used in aerospace and defense fields. It can make certain metal materials and fuels, such as liquid hydrogen, more stable, and improve the performance of weapons such as rockets and missiles.

Ultra-low temperature refrigeration can also facilitate the storage and transportation of energy. For example, the use of superconducting materials and ultra-low temperature refrigeration can improve the energy efficiency of certain electronic devices.

In short, ultra-low temperature refrigeration technology plays an important role in many fields. Through continuous innovation and technological improvement, more emerging applications may emerge in the future.
