Abstract

There have not been many previous studies on the thermal parameters of oyster shell walls, especially when it comes to the calculation and analysis of unsteady heat transfer. In this study, the thermal parameters of oyster shells were first determined using a Hot Disk experiment. Secondly, a single-room calculation model of the enclosure’s structure was established. Using a methodology based on unsteady convolution calculation combined with a Maple mathematical software model, a proposal was made to analyze the indoor temperature response of the enclosure structure under thermal excitation caused by external disturbance. This method was used to develop indoor temperature response images of five different structures, including oyster shell walls, and to rank their respective thermal insulation performances. The results of the analysis show that the structure of the oyster shell wall enclosure displayed excellent thermal insulation performance. It was found to have a similar performance to the 30 mm thick EPS board thermal insulation structure. Third, BECS energy consumption software was used to simulate the outdoor thermal excitation response under five different enclosures to obtain the respective insulation performances of each structure. Finally, the oyster shell walls have demonstrated an overall high thermal insulation performance.
