- Airports are among the most energy-intensive buildings in the commercial sector. Vast terminals run 24/7 with high fresh-air requirements, large glass facades, and constantly moving passenger loads. Heating and cooling the ventilation air alone can account for 40-60% of a terminal's HVAC energy. Air-to-air heat recovery is the single highest-return measure to cut that load.
- Terminal buildings exhaust enormous volumes of conditioned air through lavatories, lounges, and concourses while simultaneously drawing in equal volumes of outside air. Without recovery, that energy is thrown away. A rotary heat recovery wheel or a plate heat exchanger transfers sensible (and, with enthalpic media, latent) energy between the two streams before they leave the building.
- Rotary wheels suit very large airflows (tens of thousands of m3/h) where a compact footprint matters. Plate exchangers are preferred when supply and exhaust must stay strictly separated. Run-around coil loops are used when supply and exhaust ducts are far apart.
- In heating-dominated airports, frost formation on the exhaust side is a real risk. See our guide on frost protection for heat recovery for purge sectors and preheat strategies.
- With energy costs and carbon targets rising, most airport retrofit projects recover their capital in 2-4 years. Start with a system audit, then size the exchanger to the design outdoor condition rather than the annual average.
