Achieve Next-Level Cooling Optimization with Room AFM Best Practices

Room-level Airflow Management (AFM) refers to the optimization of cooling infrastructure. It’s the only way to realize energy savings from any AFM improvements you made at the rack, raised floor and row levels. Everything up to this point is an expense without room-level cooling optimization.

CEG’s Room-level AFM strategies and solutions will improve your facility’s energy efficiency, resulting in reduced operating costs, improved cooling capacity and IT equipment reliability, and the ability to defer capital expenditures.

AFM Best Practices at the Room Level

Raised Floor
K

Reduce AC unit fan speeds. Variable Frequency Drives (VFD) and Variable Speed Drives (VSD) allow you to adjust fan speeds based on your facility’s unique operating conditions.

K

Manage humidification for energy savings. Humidity control should be applied as part of an overall IT environment strategy that also includes optimization of air management, IT load planning and infiltration minimization.

“Power in, heat out always.” Every kW of power consumed by computer room equipment becomes a kilowatt of heat the needs to be removed. Therefore, it’s important to monitor the power being demanded by IT equipment (the IT load) to properly match it with the cooling being supplied by cooling units (cooling capacity and volume).

Variable Frequency Drives and Variable Speed Drives can be added to fixed speed fans.
~
Adjusting fan speeds to meet changing load requirements is the easiest way to manage operation costs.
~
A 20% reduction in fan speed results in a 20% reduction in airflow, but a 50% savings in fan energy.

VFD & VSD

Too much or too little humidity directly contributes to reduced equipment downtime.
~
Humidification is best done at room level, not by individual cooling units.
~
CEG offers evaporated and steam humidification solutions.

Humidity Control

Match cooling capacity with IT load. Solutions that monitor power and cooling infrastructure will help create this balance.

AI and Machine Learning can help visualize AFM improvements in the rack, row and raised floor, and provide advisement on room-level cooling optimization.
