Compares the complex heat transfer coefficient at different ventilation rate and different geometric parameters of an AFW and the shading effect of blind with different angles of the louvre. Points out that adopting effective shading facility is more obvious in raising energy saving efficiency than increasing the ventilation rate or changing the geometric parameters of an AFW.
