Basics of Low-temperature Refrigeration | | A. Alekseev
; | | Date: |
29 Jan 2015 | | Abstract: | This chapter gives an overview of the principles of low temperature
refrigeration and the thermodynamics behind it. Basic cryogenic processes -
Joule-Thomoson process, Brayton process as well as Claude process - are
described and compared. A typical helium laboratory refrigerator based on
Claude process is used as a typical example of a low-temperature refrigeration
system. A description of the hardware components for helium liquefaction is an
important part of this paper, because the design of the main hardware
components (compressors, turbines, heat exchangers, pumps, adsorbers, etc.)
provides the input for cost calculation, as well as enables to estimate the
reliability of the plant and the maintenance expenses. All these numbers are
necessary to calculate the economics of a low temperature application. | | Source: | arXiv, 1501.7392 | | Services: | Forum | Review | PDF | Favorites | |
