외기를 이용한 냉방시스템 제어 전략의 에너지 절감 타당성 검토

The purpose of this study is to verify feasibility of cooling system using outdoor air by applying control strategies that are night purge, temperature control, and enthalpy control using Energy Plus in office building. Cooling energy and fan energy are mainly analyzed to consider additional fan energy consumption. As a result, the whole energy consumption of night purge and temperature control increase by fan energy. On the other hand, the whole energy consumption of enthalpy control shows energy saving. The result indicates that cooling energy as well as fan energy has to be considered to evaluate the effectiveness of outdoor air cooling system.
