Abstract
Sub-Kelvin cooling technologies are a critical technology for advanced deep space astrophysical observations. The configuration with adiabatic demagnetization refrigerator (ADR) precooled by Stirling-type pulse-tube cryocooler (SPTC) /Joule-Thomson cryocooler (JTC) is most attractive one for such space applications. In order to meet the demands of future national space science missions, the Technical Institute of Physics and Chemistry (TIPC, CAS) and the Shanghai Institute of Technology Physics (SITP, CAS) have carried out collaborative research. After separately optimizing SPTC, JTC, ADR, and efficient coupling of the three, a sub-Kelvin SPTC/JTC/ADR hybrid refrigeration system is proposed, built, and tested. The hybrid refrigeration system can achieve a no-load minimum temperature of 661 mK and maintain a temperature of 0.9 K without load for 3.78 h, setting the basis for the development of future space-application-targeted sub-Kelvin refrigerator.
期刊介绍:
The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling.
As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews.
Papers are published in either English or French with the IIR news section in both languages.
