Precision Cooling

Data Center Adaptive Control — Achieve 20-35% PUE improvement through ASHRAE compliant thermal envelope optimization, free cooling, VFD fan control, and hot/cold aisle containment.

Optimization Strategies

Each can be implemented independently; together they deliver maximum savings.

01

Supply Air SP Raise (ASHRAE Compliant)

Raises supply air temperature setpoint within the ASHRAE compliant thermal envelope (18-27°C inlet). Each degree of setpoint increase reduces compressor energy by 2-5% while maintaining equipment reliability.

20-25% savings by raising SP from 13°C to 18-22°C

02

Free Cooling (Economizer)

Leverages outdoor air or water-side economizers when ambient conditions permit. Direct and indirect free cooling modes maximize compressor-free hours, dramatically reducing annual cooling energy.

Eliminates compressor operation during favorable conditions

03

VFD Fan Speed Control

Variable frequency drives on CRAC/CRAH fans modulate airflow to match actual IT load. The cubic fan law means a 20% speed reduction delivers a 51% power reduction, yielding significant savings.

51% fan power reduction at 80% speed (cubic law)

04

Hot/Cold Aisle Containment

Physical separation of hot and cold airstreams prevents bypass air mixing. Containment enables higher return air temperatures, improving chiller delta-T and allowing higher supply setpoints without hot spots.

Enables higher SP raise and improves cooling efficiency
