Cooling and Ventilation Group

The Cooling & Ventilation group (CV) is responsible for the design, installation, commissioning, operation and maintenance of the cooling systems, pumping stations, air conditioning plants and fluid distribution systems for the whole of CERN’s accelerator complex, its experimental areas and some of the special cooling systems of the LHC experiments’ sub-detectors as well as for strategic technical installations such as the Computer Centre. 

In order to fulfil its mandate, the group performs computational fluid dynamics (CFD) simulations, along with studies on fluid dynamics, heat transfer, ventilation, smoke behavior and the propagation of gases and radio nuclides. The results of these studies are used to optimize existing installations and design future installations.

Ingo Ruehl is the Group Leader of the EN-CV Group in charge of procurement and operation and maintenance of cooling, ventilation and air conditioning systems for the accelerators and experimental areas. EN-CV also operates the fluids distribution systems for the Laboratory (drinking water, compressed air, etc.)
