Replication Data for: A numerical study of the R744 primary cooling system for ATLAS and CMS LHC detectors

A new R744 refrigeration system is needed to cool down the detectors, namely ATLAS and CMS, of the Large Hadron Collider (LHC) at CERN in Geneva. A R744-R744 cascade system is planned having a primary 2-stage compression loop and an oil-free, pumped secondary loop. To guarantee a stable and reliable operation of the plant, on one hand, two demonstration plants are built: System A for the evaluation of its control logic and System B for the analysis of the behavior of the refrigerant regarding the height difference (78m). On the other hand, simulations are done in Dymola tool. Two data sets extracted from the demonstration plant (System A) on-site as well as the results of the simulations are stored here.
