Abstract:

A dynamic test of the heat-collecting efficiency of different types of collectors was carried out to study the heat-collecting efficiency of flat solar air heaters. The results showed that the temperature at the air outlet and theheat collecting efficiency of the solar air heater with a perforated absorber flat plate were apparently higher than those of the solar air heater with a nonporous corrugatedabsorber plate. Therefore, the former solar air heater was proved to be able toabsorb more radiant heat energy from the sun to increase the heat convection between the absorber flat plate and the air.

Key words: solar air collector; heat-collecting efficiency; dynamic test
