OPTIMIZING PCM CAPSULE SHAPE FOR ENHANCED BUILDING ENVELOPE THERMAL MANAGEMENT

Building energy consumption may be greatly decreased by integrating passive latent heat thermal energy storage systems with phase change materials (PCM). These systems may successfully adjust interior temperatures by utilizing PCM's thermal storage properties, which reduces the need for active heating and cooling systems. By reducing peak energy loads and enhancing overall thermal management, this technique improves energy efficiency and advances sustainable building design. This research examines the thermal performance of walls in buildings in Miskolc, Hungary. The thermal performance of different capsule shapes containing phase change materials embedded in the building envelope was evaluated. The nonlinear governing equations were resolved by applying the finite volume method. This work provides strong evidence that the ideal shape of a phase change material capsule may be systematically determined by constructing a thorough mathematical model. The method of determining is closely related to the thermal characteristics of the phase change material, the geometry of the capsule, and the environmental conditions. The chosen capsule shape will optimize thermal efficiency and performance in various application scenarios thanks to this model's accurate optimization, which considers the intricate interactions between these elements.
