An experimental air heater having a selective black thin-channel absorber and one glass and two Teflon glazings was designed, fabricated, and tested. The performance of the heater proved to be superior to many current state-of-the-art air heaters. A steady-state performance model was formulated. An energy balance was performed on each element and the resultant set of nonlinear equations was solved iteratively to predict the collector's performance. The maximum discrepancy between the predicted and experimental performance characteristics was less than 2 percentage points. Sensitivity studies were done to study the effect of various design parameters on the collector's performance, and the results of those studies are presented.
