Dynamic simulation of a 1.8K refrigeration unit for the LHC

A new simulation toolkit has been successfully developed at the European Organization for Nuclear Research (CERN) and applied to existing cryogenic installations as, for example, the 1.3kW @ 4.5K cold-box of the Compact Muon Solenoid (CMS) experiment and the central CERN helium liquefier.

Descripción
Sumario:A new simulation toolkit has been successfully developed at the European Organization for Nuclear Research (CERN) and applied to existing cryogenic installations as, for example, the 1.3kW @ 4.5K cold-box of the Compact Muon Solenoid (CMS) experiment and the central CERN helium liquefier. The simulator is based on different interconnected simulation tools and provides simulations of cryogenic systems with their control and supervision. In this paper, we present an application to a complete 2.4kW @ 1.8K refrigeration unit for the LHC. It includes the cryogenic centrifugal compressors coupled to the warm compression station.
