In addition to cleanroom technology and the resulting requirements for ambient air, “clean” cooling is also becoming increasingly important in building services engineering.
In addition to the effects of the EU's F-gas Regulation, a growing number of people are becoming aware of the risks to the environment posed by the continued use of PFAS, HFO, and TFA.
The use of natural refrigerants is gaining in importance, although new challenges for building services engineering must also be taken into account.
InfraSolution has designed and implemented two CO2 refrigeration systems for CERN. These systems provide a temperature of -55 °C at a depth of 90 m below the earth's surface for the ATLAS and CMS detectors in France and Switzerland.
This additional cooling is necessary to meet the increased demands of the next generation of measurement technology. However, being so close to the triple point, it also places high demands on the measurement technology and control behavior of the related components.
In our presentation, we provide insights into the decisive steps of technical implementation and project management.
