Abstract: It is introduced, a solar
circular collector, arrange in parallel where blower is
connected in cooperation with main fold of mild steel
pipe having small thickness .Collector design in such a
way that air flow in each absorber tube is uniform. Four
assamblies of collector is opened in air outlet unit
where air received. The experiments are conducted for
varying flow rate of air during a day time, and also
using solar radiation of clean day through the seasons.
The efficiency of solar air heater is decrease in time
periods of afternoon and increase at the morning and
evening, its due to fact that the heat gain during
afternoon is decrease due to increase in ambient
temperature and also at the same time duration solar
radiation received on collector surface is high.
Moreover, the heat transfer performance of the solar air
heater with single circular glass-covers air passes is
analyzed, and the heat transfer method for calculation
are applied.
