Why It Matters

Data centers run 8,760 hours a year and reject enormous heat. Ventilation and cooling dominate the energy bill, so any recovery compounds into large savings because the duty never stops.

Typical Energy Savings

A rotary enthalpy wheel combined with free cooling can cut annual cooling energy by roughly 30 percent. Even a sensible plate core removes a large share of the fresh-air conditioning load.

Recommended Technology

• Rotary enthalpy wheel for high effectiveness and humidity control
• Air-to-air plate core where isolation is preferred
• Economiser cycle to maximise free cooling hours

What to Watch

• Maintain strict separation if using plate cores near clean air paths
• Size for part-load, since that is where most hours are spent
