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.
