Chiller Configuration Original required configurations: – Configuration A: Three redundant chillers each with a capacity of 50% of total power. – Configuration B: One chiller 100% power chiller with redundant compressors + 2 low power chillers (one of them air cooled). Final configuration by J&E Hall: – Two full power chillers (one with air cooled condenser for warm operation). – The two full power chillers cost half the price of any of the original required configurations. – One chiller has been ordered. The second (redundant) chiller is planned to be ordered in a later stage of the project. 20 October, 2011Thermosyphon cooling workshop §55
