Özet

The main objective of this study is to experimentally investigate the effect of placing phase change material (PCM) inside the horizontal mantled hot water tank on thermal energy storage (TES) performance. Six cylindrical paraffin tubes made of glass of 1 liter were placed inside the mantled hot water tank storage tank side by side vertically, respectively. At the end of this study, it was found that using paraffin inside the hot water tank increased the TES capacity and amount of hot water obtained from the tank. The amount of obtained hot water didn’t increase proportionally with the increase of the amount of paraffin, as the volume of the tank was constant. Because the amount of hot water in the tank decreased with increasing the amount of paraffin. The stored energy in the paraffin wasn’t transferred to the water efficiently. In order to obtain the highest volume of hot water, 4 tubes paraffin should be placed inside the tank. Discharging period duration could be increased 17 minutes with 4 tubes paraffin. Each added 1-liter paraffin reduced the temperature in the tank by nearly 1 °C.
