SWITZERLAND: Daikin has supplied a further eight water-cooled chillers to the CERN nuclear research facility for the High-Luminosity Large Hadron Collider which is due to be operational from 2029.

The Large Hadron Collider (LHC) is the most powerful particle accelerator ever built. The accelerator sits in a tunnel 100m underground at CERN, the European Laboratory for Particle Physics, on the Franco-Swiss border near Geneva, Switzerland. The 27km long accelerator is used to boost beams of particles to high energies before they are made to collide with each other. The process gives the physicists clues about how the particles interact and provides insights into the fundamental laws of nature.

The High-Luminosity LHC, which should be operational from the beginning of 2029, will allow physicists to study known mechanisms in greater detail, such as the Higgs boson, and observe rare new phenomena that might reveal themselves. For example, the High-Luminosity LHC will produce at least 15 million Higgs bosons per year, compared to around three million from the LHC in 2017.

The heat generated by the increased Luminosity of the Large Hadron Collider will be dissipated by four Daikin EWWH-VZ water-cooled inverter screw chillers on R1234ze and four EWWS-J water-to-water heat pump on R513A. Total cooling capacity is 3.8MW.
