This article describes the development of a CFD 2D model of a new type of ventilated active façade which includes a PCM (Phase Change Material) in its outer layer. The model was carried out using the software Fluent. The numerical results were compared against experimental data obtained by...

Numerical modelling is commonly used to design, analyse and optimise tube-in-tank phase change thermal energy storage systems with fins. A new simplified two dimensional mathematical model, based on the effectiveness-number of transfer units technique, has been developed to characterise...

This work focuses on the preparation of AC (activated carbon) through a physical activation method using peat soil as a precursor, followed by the use of the AC as an inorganic framework for the preparation of SPCM (shape-stabilized phase change material). The SPCM, composed of n-octadecane as...

The application of thermal energy storage (TES) system with phase change material (PCM) is an effective way for energy conservation and greenhouse gas (GHG) emission reduction. Global warming is increasing along with the energy consumption. Many researchers are concerned about this present...

In order to really assess the potential of Phase Change Material (PCM) wallboards, a renovated office building has been monitored during approximatively one year. A room was equipped with PCM wallboards in the lateral walls and in the ceiling. Another room, identical to the first one, was not...

The quest towards energy conservative building design is increasingly popular in recent years, which has triggered greater interests in developing energy efficient systems for space cooling in buildings. In this work, energy efficient silver–titania HiTES (hybrid nanocomposites-based cool...

A series of MicroPCMs with gelatin-gum arabic shell, polyurethane shell and styrene-based copolymer shell were fabricated via complex coacervation, interfacial polymerization and suspension polymerization, respectively. Furthermore, a novel MicroPCMs with styrene-divinylbenzene copolymer as...

Three kinds of macro-encapsulated phase change materials (MacroPCMs) were fabricated, i.e., MacroPCMs with a single core–shell structure, MacroPCMs containing microencapsulated phase change materials (MicroPCMs), and composite macrocapsules of MicroPCMs/expanded graphite prepared by...

Thermal energy storage (TES) has the capability to absorb, store and release heat based on dynamic surrounding environmental conditions. Sensible energy storage captures or releases heat with changes in material’s temperature while latent heat is associated with a phase change at an isotherm...

Microencapsulation of phase change materials (PCMs) is an effective way of enhancing their thermal conductivity and preventing possible interaction with the surrounding and leakage during the melting process, where there is no complete overview of the several methods and techniques for...
