Abstract

A solar chimney pilot plant as a power conversion unit has been designed, built and tested in Tanta with 24 m chimney height and 1600 m2 collector area. Temperature distributions for transparent cover, air inside the collector, absorber surface and two points in the soil at different depth from the surface  have been measured along the radius of the collector at different distances from the center of the collector. Air velocity and temperature at chimney entrance also have been measured. Temperature of transparent cover, air inside the collector and absorber surface are affected directly by solar radiation and they reach to their peak with peak of solar radiation, while temperature of soil at upper layer reaches to its peak with sunset and the temperature of soil at lower layer does not change during measuring period but these temperatures have different values at different measuring position along the radius of the collector. Air velocity increases with increasing temperature difference between air at chimney entrance and the ambient which reaches to a mean value of  5 m/s in the period between 8 AM and 4 PM at  mean temperature difference of 23.5oC and mean solar radiation of 812 W/m2.
