멀티존 변풍량 터미널 유닛의 풍량 제어 방안에 관한 연구

The increasing social interests for energy saving has highlighted the need for more buildings with variable air volume (VAV) systems. In order to control the VAV system at multi-zone, it is essential to control terminal unit installed in each zone. This research proposes control method with ventilation requirement of VAV terminal unit in multi-zone. And the conventional and proposed control algorithms were compared through a TRNSYS simulation program. The proposed VAV terminal unit control method satisfies all the conditions of indoor thermal comfort and indoor air quality. An energy comparison with the conventional control method showed that, the method satisfies not only the indoor thermal comfort and IAQ, but also reduces the energy consumption.
