| Abstract | ||||
| The solar chimney is a simple and practical tool that is applied to enhance space natural ventilation. This paper reports an experimental work to investigate effects of number of solar chimneys, chimney height, air gap width, and chimney orientation on natural ventilation in a space. Temperatures and velocities profiles were recorded through both chimney channel and room connected to channel under different parametric conditions. The results show that improvement in natural ventilation could be achieved using multi solar chimney. Also, using one, two, or three chimneys could reduce the room center temperature by 6%, 10%, and 12 % respectively, and using two and three chimneys instead of one chimney increased ventilating flow rate to 13% and 33% respectively. | ||||
