Common is the common household refrigerator freezer, is accused of temperature range in -
18 degrees Celsius to 10 degrees Celsius of refrigerator, and cryogenic refrigerator temperature control is lower, can achieve -
To - 40 degrees Celsius
150 degrees Celsius, or even to reach a lower temperature.
due to the nature of cryogenic refrigerator temperature is very low, it can only be used in some special industry or use, below we simply to introduce you to some, hope to help everyone's cognition.
1.
Physics and biology research
it is well known that many research projects shall be carried out at very low temperatures, such as superconductor research, biological research.
Superconductors are those at a special low temperature resistance suddenly close to even reach zero electric conductor, according to the experience of the previous studies showed that they need to be in low temperature condition to show the characteristics of the superconductor, some electrical conductor superconducting incredibly even under low temperature, in addition, biology is sometimes need low temperature environment.
Therefore, the application of cryogenic refrigerator to scientific research is inevitable.
2.
Medical
we know that most of the body from the medical diseases are caused by bacteria or viruses, bacteria and viruses are strong adaptability of microbes, research on the survival of microorganisms in low temperature environment is one of our medically important topic.
Through the study of low temperature environment we can know the survival of microorganisms of maximum limit, to help us deal with disease, protect people's health.
At the same time, ultra-low temperature freezer can also help us save blood, drugs, etc. , greatly extended the use of their time and increase the inventory of hospital.
3.
Chemical
chemical study also inseparable from the low temperature, a lot of chemical substances in different environmental temperature often some special happens.
Such as composed of protein enzyme will happen in the low or high temperature environment the change of the molecular structure, lose its own special chemical and physical properties, therefore, chemical research also cannot leave the ultra-low temperature freezer.
4.
Fishing
fishery is a maritime industry, ocean fishing because of far distance land, fishing cycle is long, therefore requires some can provide ultra-low temperature environment of the refrigerator to save fish, prevent deterioration.
Such as deep sea fish, such as tuna gather at low temperature cold preservation, refrigeration, etc.
cryogenic refrigerator are seldom used in our daily life, its particularity, the purpose of it.
