Energy and Exergy Analyses of A Novel Model Trombe Wall System Using Natural Zeolite‐Perlite Composite Plates

ABSTRACT In this study, the experimental performance of a model Trombe wall application using perlite‐enhanced natural zeolite composite plate a thermal mass was evaluated. The production and basic parameters of the perlite‐added natural zeolite plate were given, energy and exergy analyses were carried out with the data obtained from the test results, and the results were compared with similar ones in the literature. For the first time in the literature, a Trombe wall model using a natural zeolite‐perlite composite plate as the thermal mass was experimentally evaluated and subjected to energy and exergy analyses. The experiments revealed that the composite Trombe wall (CTW) achieved a maximum indoor temperature of 38°C, with a notable 11.5°C temperature difference between indoor and outdoor conditions. Energy efficiency of the system varied from 21% to 70%, while exergy efficiency ranged from 0.05% to 1.10%. These results suggest that the CTW system, utilizing natural zeolite‐perlite composite plates, is a promising solution for enhancing energy efficiency and thermal comfort in buildings. This study aims to contribute to future research on energy efficiency in nearly zero‐energy buildings (nZEBs) and related structures.
