IMPROVEMENT OF NATURAL VENTILATION IN BUILDING USING MULTI SOLAR CHIMNEYS AT DIFFERENT DIRECTIONS

Summary

Laboratory tests on a room ventilated by one to three solar chimneys, varying chimney count, height, air gap and facing direction while measuring air speeds and temperatures. Adding chimneys strengthens natural ventilation: compared with a single chimney, three raise the airflow by about a third and lower the room-centre temperature further.
