The application range of low-temperature control technology is very wide, ranging from biological research, rocket aircraft, public security fire protection, to daily life refrigerators, refrigerators, greenhouse planting... In short, low-temperature technology is indispensable in all aspects. At present, low-temperature technology has penetrated into many relevant disciplines and application fields, and become an indispensable and important force to promote the development of science and technology, economy, military and life. Peugeot takes you to understand these unknown applications.
1. Liquefaction and separation of gases
The liquefaction and separation of gases is the most important application range of cryogenic technology. For example, the liquefaction and separation of air accounts for almost one third of all activities in the field of cryogenic engineering
2. Superconducting applications
Another very important application of cryogenic technology is combined with superconducting applications. Since the transition of materials from normal state to superconductive state is from "disorder" to "order", superconductivity can only occur at a certain low temperature. So far, all superconducting devices can only work in low temperature environment, and the development of cryogenic technology, especially cryogenic technology in liquid helium temperature region, is driven by superconducting technology, which determines the close relationship between cryogenic technology and superconducting technology.
3. Medical
Cryogenic technology is also widely used in medical and health care. In the early stage, it is mainly used for skin, oral cavity, gynaecology and other diseases on the "surface" of skin and mucous membrane.. Later, with the continuous accumulation of treatment experience and the rapid improvement of the level of frozen medical devices, cryotherapy has been able to operate on tumors and cancers of the respiratory system, urogenital system, digestive system, skeletal system, brain and nervous system and other internal organs.
4. Energy
The application prospect of low-temperature technology in energy is clear. The energy structure based on oil and coal is not only threatened by resource depletion, but also brings increasingly serious environmental pollution and greenhouse effect. Natural gas can alleviate the problem of environmental pollution, especially by replacing coal and vehicle fuel in a large amount. It is an economical and effective scheme to use liquefied natural gas for large-scale storage and long-distance transportation of natural gas.
It turns out that low temperature is so widely used in these large fields. With the development of technology, the development of low temperature technology will be better and better in the future.
