3. Linac3 - Reasons for HVAC consolidation
Ref. ECR L3-U-EC-0001 (EDMS )
Reasons for ventilation consolidation:
The increase of the equipment dissipated heat loads;
The obsolescence of existing ventilation units and related components;
Ventilation and smoke extraction functions not separated;
Reasons for new technical room (IPR approved in September 2018) :
Reduced available height of existing room, not compatible with the increase of the flow rate and with the installation of standard dimensions air handling units;
Reduced admissible load, not compatible with heavier air handling units;
Presence of asbestos in the sealing of joints of the slabs;
Lack of water tightness.

5. Linac3 - Available drawings
3D models used for integration of new ductwork:
ST _01 HVAC 3D model
ST _01 Building Linac3 modified by CV

6. Linac3 - New ductwork
Due to space constraints and lack of passages, new ductwork is installed in the same volume occupied by the existing one;
Horizontal distribution:
Ceiling mounted in tunnel and hall zones (no interference with overhead crane)
Ceiling mounted in triangle zone;
Vertical distribution: existing vertical niches;
No return ducts will be installed: existing technical room will become a return plenum;

7. Linac3 - Main ductwork changes
At underground of triangle zone: one air outlet grill to be re-displaced (now hidden behind the stairs)
