Abstract: A novel Trombe wall design that incorporates highly thermally conductive materials along with nano-enhanced phase change material is presented. Performance analysis is conducted using finite element method simulations. A comparative study of NePCM and PCM in a room with a Trombe Wall revealed minor differences in thermal performance during January, February, and December, but a significant discrepancy in March due to higher solar radiation levels. The enhanced latent heat storage capability of NePCM contributed to a more sustained temperature increase during periods of intense solar radiation. Over seven months, NePCM demonstrated a 16% higher average energy gain compared to PCM, attributed to its improved thermal conductivity and heat transfer efficiency. These findings indicate that nano-enhanced phase change materials are more effective than their non-nano counterparts. The results indicate a substantial impact of the system, raising room temperatures to 22°C during the day and resulting in significant energy savings.
