Group spaces by schedule and exhaust quality, mechanical rooms and lounges on their own loops, so each exchanger runs near its design point instead of averaging across very different loads. Demand-controlled ventilation, trimming outdoor air to occupancy, raises the recovered-energy fraction because the streams stay balanced. Coordinate recovery with the building management system so free cooling and heat recovery share the load by season. Security and fire compartments also shape duct routing, which is where run-around coils help when supply and exhaust shafts are far apart. Most airport programs pair an energy audit with a phased rollout to limit disruption to live terminals.<\/p>\n<h2>Questions fr\u00e9quemment pos\u00e9es<\/h2>\n<p><strong>Which recovery type suits a large terminal?<\/strong><br \/>Rotary wheels suit very large single airflows where footprint matters, while plate exchangers are preferred when supply and exhaust must stay strictly separated.<\/p>\n<p><strong>How is frost handled in cold climates?<\/strong><br \/>Use purge sectors on wheels or pre-heat and defrost bypass on plates, sized to the winter design day rather than the annual average.<\/p>\n<p><strong>What payback can airports expect?<\/strong><br \/>Most terminal retrofits recover capital in roughly two to four years, faster where heating degree days and operating hours are high.<\/p>\n<div class=\"yc-related\">\n<h3>Articles connexes<\/h3>\n<ul>\n<li><a href=\"https:\/\/www.26yc.com\/fr\/why-bess-pv-inverter-counter-flow-air-to-air\/\" title=\"Why Energy Storage Cabinets and PV Inverters Use Counter-Flow Air-to-Air Heat Exchangers\">Why Energy Storage Cabinets and PV Inverters Use Counter-Flow Air-to-Air Heat Exchangers<\/a><\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Why terminals are energy hotspots Airports are among the most energy-intensive buildings in the commercial sector.
