The integration of phase-change materials (PCMs) into thermal energy storage systems offers significant potential for reducing consumption and improving comfort, crucial issues achieving sustainable building stocks. Nevertheless, the performance PCM-based is strongly influenced by container geometry. Among various forms incorporating PCMs applications, macroencapsulation most versatile is, therefore, widely used. Herewith, this paper analyzes impact macrocapsule geometry on PCM performance. Thermal properties material were first tested using Differential Scanning Calorimetry at five heating/cooling rates to evaluate its influence temperatures enthalpy. Then, an experimental setup evaluated four geometries enclosed behavior during charging discharging processes. characterization revealed that slowest-tested rate minimized supercooling effect. Analysis across different showed sectioning contact surface improved heat transfer efficiency fully mobilizing times. Conversely, double-layered designs hindered transfer, presenting challenges in completing discharging. These findings suggest optimizing a necessary direction further research, which may include adjusting operating temperature range layers or redesigning misalign surfaces.
