How should I categorize the cooling required for IT equipment in data halls. Considering that the cooling in the actual building is provided by air cooled chillers, which are listed in Table 6.8.1-3 of ASHRAE 90.1. Can I assume that, they are not process load and determine the COP based on table G3.5.3. Regarding the number of chillers does it need to be as identical as proposed building.
