Commercial Air Conditioning
A scientific approach to cooling
DAIKIN HAS DELIVERED two EWAH-TZ chill- ers with a total cooling capacity of 1312kW to the European Organisation for Nuclear Research (CERN) in Switzerland.
CERN is the largest physics laboratory in the world and the research facility has just renewed its contract with Daikin for the supply, commis- sioning and maintenance of chiller units.
Daikin has been a partner for the CERN lab since 2012 providing units with a total cooling ca- pacity of over 31 megawatts, including screw in-
verter, centrifugal and scroll chiller technology. CERN laboratories sit across the Franco- Swiss border near Geneva and were founded in 1954. CERN hosts nearly 13,000 visiting scien- tists and engineers representing 399 universi-
ties and research facilities per year.
CERN is also home to the Large Hadron Col-
lider (LHC), the most powerful particle accelera- tor ever built.
Daikin chillers are used to meet CERN’s needs in terms of process cooling. This includes cooling
for data centres, for various experiments cur- rently conducted at CERN and for the air condi- tioning systems to cool the underground tunnel where the Large Hadron Collider sits.
The Large Hadron Collider in particular – for the size and the function – requires cooling on an unusually high scale, plus absolute precision in terms of temperature control.
Daikin has been the chiller supplier of choice by CERN, thanks to the wide range of solutions offered, from small capacity scroll compressor units, low noise emission units to high efficiency inverter driven products and high capacity cen- trifugal chillers.
“THE LAB REQUIRES ABSOLUTE PRECISION IN TERMS OF TEMPERATURE.”
Head of the cooling & ventilation group at CERN, Anders Andersen, said Daikin chillers have proven to be reliable.
“We have been working with Daikin for sev- eral years now, so we have a lot of experience with them. They able to satisfy the needs of CERN applications,” he said.
