Others (1/5): Backup chiller for IT, TT and

VELO cooling stations

DESCRIPTION An air chilled fridge unit (32 kW cooling capacity) shall be provided as a backup for the IT, TT and VELO cooling systems, in order to supply mixed water at 13°C in case of breakdown or maintenance of the standard network. The chiller will be located on top of the barracks and equipped with automatic valves.

Others (2/5): SPD/PS detectors air cooling

DESCRIPTION The electronic acquisition cards for the SPD and PS, dissipating a total heat power of about 4.4 kW shall be cooled down with a

dried and filtered air flow at 6 bar pressure. All components of the cooling system shall be positioned into a zone of the protected area still to be defined according to technical

and integration matters.

Others (3/5): Muon on-detector air cooling

DESCRIPTION The on-detector electronic, fitted with the Muon chambers in stations M1-M5 shall be cooled by means of a forced air circulation. The air will be taken form the bulk by a fan, and exhausted to the bulk, the cooling capacity being assured by the cavern ventilation system.

The heat dissipated by on-detector electronic is 3.5 kW for station M1, 3 kW for stations M2 and M3 and 2 kW for stations M4 and M5.
