摘要
This paper deals with the performance of solar chimneys at different inclination angles and for various gaps between glass and absorber plate for the location Tiruchirappalli (78(circle)69'E, 10(circle)81'N). During experiments, the highest rate of ventilation was found to be about 0.32m(3) at a solar radiation intensity of 1000W/m(2). Compared with vertical chimneys, the height of an inclined chimney is 25% less than the structure height and there is no variation in efficiency between them.
