Cooling problems• Server manufacturers specify inlet air temperatures
• Conventional controls don’t measure it
• Overcooling
• Inefficiency
• Hot spots
![Page 3: Intelligent Energy Management Made Simple](https://reader036.vdocuments.us/reader036/viewer/2022081520/5681680b550346895ddd91a3/html5/thumbnails/3.jpg)
Cooling control is difficult• Open plan design
- All cooling units affect all areas
• Redundant cooling units - Can lead to “fighting”
• Custom control software is expensive and unreliable- Can’t have a PhD commission every datacenter

How we do it• Measure inlet air temps
• Supervisory control
• Learning algorithms
• Installed in days
Wireless Module
Temperature Probes

Case Study 1 – Franchise Tax Board
• The Data center:- 10,000 SF- 12 CRAH’s (22 tons each)- 40% built out
• The solution:- 50 wireless inlet server temperature sensors- 4 VFDs installed- Re-arranged tiles- Reset setpoints of CRAHs- Automatic start-stop of CRAHs

Case Study 1 – Energy Savings• Software shut off 6-8 CRAH units
- All temperatures within ASHRAE recommended range
• 310,000 kWh/year saved- 245,000 kWh/year fan savings- 65,000 kWh/year chiller savings
• $27,900/year saved ($0.09/kWh)
• 58% reduction in fan energy usage
• 13.4% reduction of total datacenter energy usage

Case Study 2 – Energy Savings
• 300,000 kWh/year saved- 218,000 kWh/year verified fan savings- 82,000 kWh/year estimated chiller savings
• $27,000/year saved ($0.09/kWh)
• 80% reduction in fan energy usage
• 17% reduction of total datacenter energy usage
