A sequence of tests was performed on these models for the two air circulation models （forced and natural） in order to compare their thermal performance. The results are presented in terms of useful energy, stored energy and thermal efficiency of each model.展开更多
文摘An experimental study was conducted on three models of solar collectors having an absorber made of concrete designed and built in the TPL （Thermal Process Laboratory）. A sequence of tests was performed on these models for the two air circulation models （forced and natural） in order to compare their thermal performance.
