Abstract
In this paper, a Trombe wall is simulated with 4 blocks of degreaser and 4 blocks without PCM. This wall is located in a room with dimensions of 3 by 4. This study performed two placements of PCM and non-PCM blocks in a period of 600 min. Trombe wall thickness has also changed in the range of 10 to 40 cm. The results showed that at a wall thickness of 10 cm in case A, from 300 to 420 min, all PCM blocks and in case B, they became solid at a time of 240 to 480. By increasing the wall thickness of the Trombe, the number of blocks that solidify completely in 600 min is reduced and by 10 cm in wall thickness in case A from 300 to 420 min, all PCM blocks and in case B in time 240 to 480 are solid. And the Trombe wall temperature decreased. Using 10 and 20 cm thick walls cannot provide the required room temperature for up to 600 min. The neural network showed that if the wall thickness reached 40 cm, 50% of PCMs would remain inside the wall without any phase change.
