Data centers and other mission-critical facilities are among the most energy-intensive built environments: nearly all the electricity they draw ends up as heat that must be removed. Heat recovery captures that waste heat and reuses it—pre-cooling incoming air, reheating supply air, or feeding adjacent loads—directly lowering PUE and operating cost. This hub collects our articles on heat recovery and advanced cooling for servers, energy storage, EV charging and power electronics.

Frequently Asked Questions
What is data center heat recovery?
It is the capture and reuse of heat removed by the cooling system—typically via air-to-air or liquid-coupled heat exchangers—to pre-condition incoming air or supply nearby thermal loads, reducing the energy needed for cooling.
How much can heat recovery save in a data center?
Savings depend on climate and layout, but sensible heat recovery on the exhaust airstream commonly cuts cooling energy by 20–40%, improving PUE materially in both free-cooling and compressor-based designs.
Which heat exchanger suits data center cooling?
For hot exhaust air, polymer (enthalpy) plates resist corrosion and recover both sensible and latent heat; for high-temperature liquid loops, plate or brazed exchangers and rear-door/liquid-coupling approaches are common.
Does heat recovery work with liquid cooling?
Yes. Liquid-cooled racks reject heat at higher temperatures, which is ideal for heat reuse (e.g., to adjacent offices or water loops) and pairs well with liquid-coupled recovery at the facility level.
