The cycles are considered from the simplest (Joule Thomson) to the most complicated ones for the very large refrigeration plants and, finally, those operating at temperatures lower than 4.5 K..The focus then turns to the operation, ability and limitations of the main components, including room temperature cycle screw compressors, heat exchangers, cryogenic expansion turbines, cryogenic centrifugal compressors and circulators. The book also describes the basic principles of process control and studies the operating situations of helium plants, with emphasis on high level efficiency...A major issue is helium purity, and the book explains why helium is polluted, how to purify it and then how to check its purity, to ensure that all components are fille | | 出版日期 | Book 2020 | | 關(guān)鍵詞 | Materials for cyrogenic engineering; Heat exchangers for cyrogenics; Helium refrigeration and liquefac | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-030-51677-2 | | isbn_softcover | 978-3-030-51679-6 | | isbn_ebook | 978-3-030-51677-2Series ISSN 0538-7051 Series E-ISSN 2199-3084 | | issn_series | 0538-7051 | | copyright | Springer Nature Switzerland AG 2020 |
