摘要
-40^-80℃的超低温被广泛应用于食品加工、石油化工、生物制药、科学实验等领域。文章主要介绍了超低温制冷系统及其所用制冷剂和压缩机的研究进展,通过对国内外的技术分析比较,指出未来超低温制冷装置的发展可从自复叠制冷系统优化、制冷剂替代采用天然工质、压缩机变频技术和CO2压缩机性能等方面进行进一步研究。
Ultralow temperature of-40 ℃--80 ℃is mainly used in the fields such as food processing,petrochemical industry,biological pharmacy and scientific experiments.The ultralow temperature refrigeration system and the research progress with refrigerant and compressor were introduced.Based on the comparison with the current research at home and abroad.the future development of ultralow temperature refrigeration unit can be optimized from the autocascade refrigeration system,and the natural refrigerants as a substitute can also be concerned,further studies for the compressor inverter technology and other aspects of CO2compressors＇ performance.
