Minutes of the B513 Planning Meeting, 9th
May
Present: Tony Cass, Anne Funken, Jukka Lindroos, Dick Minchin, Dave Underhill
Chilled water capacity |
2400kW |
Less equipment overhead |
550kW |
Less cooling needed to counter solar heating of the machine room |
210kW |
Leaves available cooling capacity of |
1640kW |
Of which office air conditioning takes |
500kW |
Leaving cooling capacity for equipment areas of |
1140kW |
ii. Jukka will measure the air flow in B513 offices to determine the exact cooling requirements. These measurements should cover both the ground floor corridors and also the 1st/2nd floor corridors on the Jura side which are cooled by the machine room air flow.
a. Adding an additional chiller in the cooling station. Space could be made available by removing one of the humidifiers (these are not so essential for today’s equipment.) The cost for this option was estimated at about 350KCHF after the meeting.
b. Utilising spare chilled water capacity from the booster. This option has not been further investigated.
Removal of sprinkler and “Cray cooling” pipes from the vault |
16000CHF |
Transfer of chilled water pumps from the MG room and removal of associated pipework |
5000CHF |
Removal of MG room false floor |
7500CHF |
Demolition of old air conditioning units and removal of separating wall |
14000CHF |
Removal of wooden walls for S/421-423-425-427 |
3300CHF |
ii. The last item is not required for the present. The removal of the MG room air conditioning units will depend on Jukka Lindroos’ studies (see 1.2.2.v above).
