Slide2POWERING for CO2 Colling plant VELO+UT
Power available on VELO platform today:
~40 kWESD106: 16A MonoESD109: 16A Mono ESD205: 16A Tri
(~18kW)EXD1305: 16A MonoEXD1307: 16A MonoEXD1306: 10A Tri EXD1311: 10A Tri
(~21kW)
Need for future CO2 cooling systems:(Burkard email to Heinrich-> IBL Atlas specif)UPS: 70kW !!
UPS1: 63A Tri + 16A Tri + 16A MonoUPS2: 16A MonoEXD: 58kW63A Tri16A Tri16A Mono
Possibility if UPS1+2 really need:
-use a part of both 100kVA ‘Online’ (less used after LS2)? -installed new: 2x20kVA (maxi) possible near the 10kVA MSS+DSS in place-find new area for 1x100kVA ?
-use ‘local’ UPS (have few old ‘Online’ APC 10kVA)-> ok with redundancy
Do Velo+UT
need the same ‘cooling power’ of IBL ? (same electrical power)Do we want also +/- the whole system on UPS ?
Slide3POWERING for CO2 Colling plant VELO+UT
Velo platformReuse the EXD13 switchboard (58kW power to be checked, need new breakers, new cables: + 5
kCHF?) Reuse ESD power for ‘local UPS’ 10kVA ?but need additional UPS power
PZ AlcoveInstall a new EXD switchboardBreaker ABB 250A: 5kCHF
150mm2 cables with installation:4.5kCHFCable trays:1.75kCHFSwitchboard: 10-12kCHFTotal: 20-25kCHF
for Both (if Uninterruptible power confirm)Install new UPS, new switchboard, new cables
Compare different location in term of ‘electrical cost’
Conclusion: cost difference difficult to estimate today (depend on UPS solution)
PZ Alcove ~ 20
kCHF
more but finally could be not a high % of total electrical cost
