COMMISSIONING OF A COUPLED EARTH TUBE AND NATURAL VENTILATION SYSTEM

摘要

The environment and energy performance of an actual coupled earth tube and natural ventilation system in a gymnasium was measured during the post-acceptance step in winter and summer at natural ventilation states. Since the measurement result at design weather condition has not been obtained, the authors calculated the natural ventilation air volume and the indoor temperature in winter, summer and intermediate season at a windless state by the use of CFD (Computational Fluid Dynamics) coupled analysis method with natural ventilation.
