Effect of Air Velocity and Solar Radiation Intensityon Performance of the Trombe Wall Heating System

These days, the heating system of the Trombe wall is known as one of the important passive solar energy saving technology, this system reduces the consumption of other energy sources. Optimum performance of the Trombe wall is influenced by parameters like solar radiation intensity, glass type, air flow convection on channel. In this article, the effect of air velocity variation on the glass and the Trombe wall temperature due to the thermal radiation intensity are analyzed. The results show that the glass temperature rise and the Trombe wall temperature decline are occurred by the air flow velocity increase. Results show that with increasing velocity from 0.14 to 1.2 m/s, the wall temperatureis decreased to 0.81. Whiles the glass temperature is enhanced 0.083 by the same velocity variation.
