공항 HVAC & 에너지 회수: 터미널 에너지 사용 절감

Why terminals are energy hotspots

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.

Why recovery matters here

터미널 건물은 화장실, 라운지, 콩코스스를 통해 엄청난 양의 조화 공기를 배출하면서 동시에 동일한 양의 외기를 흡입합니다. 회수가 없으면 그 에너지는 낭비됩니다. 어떤 회전식 열회수 휠 또는 한 판형 열교환기 는 두 스트림이 건물을 떠나기 전에 그 사이에서 현열(그리고 엔탈피 매체를 사용하면 잠열) 에너지를 이동시킵니다.

Technology choices

• 로터리 휠 는 설치 면적이 중요한 매우 큰 풍량(수만 m3/h)에 적합합니다.
• Plate exchangers 는 급기와 배기가 엄격히 분리되어야 할 때 선호됩니다.
• 런어라운드 코일 루프는 급기와 배기 덕트가 멀리 떨어져 있을 때 사용됩니다.

투자 회수

에너지 비용과 탄소 목표가 상승함에 따라 대부분의 공항 리모델링 프로젝트는 2~4년 내에 자본을 회수합니다. 시스템 감사로 시작한 후, 연평균이 아닌 설계 외기 조건에 맞춰 열교환기를 산정하십시오.

Terminal design favors zoned recovery rather than one large core. 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.

자주 묻는 질문

Which recovery type suits a large terminal?
Rotary wheels suit very large single airflows where footprint matters, while plate exchangers are preferred when supply and exhaust must stay strictly separated.

How is frost handled in cold climates?
Use purge sectors on wheels or pre-heat and defrost bypass on plates, sized to the winter design day rather than the annual average.

What payback can airports expect?
Most terminal retrofits recover capital in roughly two to four years, faster where heating degree days and operating hours are high.
