| Abstract Scope |
Phase change materials (PCM) use the latent heat of the phase change to control temperatures within a specific range. Thus, when combined with a construction material, the PCM has the potential to contribute to increased thermal comfort, reduced energy consumption for heating/cooling and change in peak energy load. The PCM transits between the solid and liquid states through the absorption and emission of heat, thus, its encapsulation is necessary to avoid causing mechanical damage to the construction material. The aim of this study has been to develop a technique for encapsulating vegetable fats in Ca-alginate shells and to evaluate the characteristics of the capsules with a view to a future application in civil construction. Core/shell capsules, with approximately 3 mm in diameter, were analyzed by DSC, TG/DTA, SEM and profilometer. The results indicate that the encapsulated PCM has the potential for incorporation in several construction materials. |
