In high-density colocation, raising cold-aisle setpoint (within the ASHRAE/TC9.9-like envelope) generally reduces chiller/CRAH energy, but is bounded by (conceptual)?
Choices
- (A) Diesel generator head only
- (B) Server/mfg inlet temperature+humidity limits, redundancy, and failure modes+ASHRAE class
- (C) Domestic 140°F always
- (D) Blower door
Correct answer: (B)
Server/mfg inlet temperature+humidity limits, redundancy, and failure modes+ASHRAE class
Explanation
TC9.9: T/RH+operational envelope+free cooling+water vs air.
