The application efficiency of the Dynamic Rotating Latent-Energy-Storage Envelope (DRLESE) system is highly contingent upon dynamic rotation timings. To gain optimal timings, six different timings were examined by employing liquid fraction, thermal storage and release, surface temperature heat flow. numerical transfer method was employed verified an experiment. Results indicated that initial occurs in forenoon, when inner aligns with sol-air temperature. Subsequently, achieving secondary possible afternoon equals PCM (Phase Change Material). Under these optimized significant enhancements performance DRLESE observed. By optimizing indoor effective release can reach up to 3182.9 kJ/Day effectiveness percentage exceeding 99.99%, flow increased 5.86%–12.26%.

The use of phase change materials (PCMs) has become an increasingly common way to reduce a building’s energy usage when added the building envelope. This developing technology demonstrated improvements in thermal comfort and efficiency, making it viable solution. current study intends provide comprehensive review published studies on utilization PCMs various constructions energy-efficient roofs, walls, ceilings. research question holds massive potential unlock pioneering solutions for maximizing usefulness reducing cooling demands, especially challenging high-temperature environments. Several issues with have been revealed, most significant which is their reduced effectiveness during day due high summer temperatures, preventing them from crystallizing at night. However, this investigates how can delay peak temperature time, number hours indoor exceeds range. Additionally, improve efficiency by mitigating need systems hours. Thus, selecting right PCM temperatures both critical challenging. Insulation density, specific heat, conductivity all play role heat transfer under extreme conditions. introduces several quantification techniques paves future advancements accommodate practical technical related materials.

Composite phase-change materials (PCMs) exhibit significant potential for enhancing the thermal performance of building walls. However, previous studies have generally lacked detailed investigations PCM-integrated walls under cold climate conditions. Therefore, in order to evaluate and wall adaptability hollow bricks with composite PCMs climates, a brick model was created by filling PCMs. Then comparative test conducted between PCM-filled conventional non-PCM-filled bricks. The experimental method index evaluation resulted following: (1) Compared bricks, showed an increase approximately 0.99 °C inner surface temperature 3.85 midsection temperature. This demonstrates that can retard rate drop, significantly insulation improvement contributes enhance indoor comfort reduce energy consumption. (2) difference interior exterior surfaces is 23.54 °C, which 5.62 higher than indicates filled possess superior heat storage capacity, effectively reducing loss, aligns principles green design. (3) flow on lower, average reduced 8.57 W/m2. suggests ability moderate flux fluctuations through “peak-shaving valley-filling” effect, contributing consumption enhanced occupant comfort.
