공기연령을 이용한 지하도상가 공조시스템 설계 기법에 관한 연구

In this study, local air-age characteristics of underground shopping center was studied by numerical analysis for the design of HVAC system. The air-age characteristics of underground shopping center was investigated with the main parameters such as inlet air quantities of store and pathway, adoption of local ventilation system, and so on. The air quality is improved 20% in air-age and 80% in air distribution by increasing inlet air quantity of store. Also, air distribution is improved 17.4% by adopting local ventilation system. From the results, the recommended HVAC system capacity of underground shopping center is 0.7 and 0.15 ccm/㎡ with local ventilation system.
