Abstract

In expander cryogenic units in addition to gas cooling, the work is also produced. The usage of expander work improves some energetic performances of cryogenic systems. The character of the change of the ratio of the expander work to that of compressor in a simple expander cycle is analyzed. The findings can be applied for more complex cycles of refrigerators and liquefier. The results of thermodynamic researches of ways to use the expander work in cryogenic units are given. Based on exergic balances in case of use of expander work, the expressions for the maximal additional amounts of cryogenic units products are obtained.
