Abstract:

The study centered on a comparison between phase change materials (PCM) and water integration with evacuated tube collectors (ETC). Temperature behavior in ETC filled with PCM and water separately was studied. Charging and discharging of PCM and water in ETC were studied. The amount of heat transferred from both systems was evaluated. During charging of PCM integrated with ETC, a steeper thermal stratification was observed as compared with water. The heat stored in PCM (ETC) was significantly higher; however, the heat discharge from PCM (ETC) was very slow as compared with that of water (ETC). Heat transfer efficiency was significantly higher in water (ETC) as compared with the PCM (ETC).

Keywords:
