“…Typically classified into three families: organic, inorganic and eutectic [4,5], PCMs have shown good stability and compatibility with the cement-based construction materials [6], thereby offering a rational and intelligent management of the energy use in buildings. From apart the environmental and economical benefits of PCMs technology, the thermal comfort of the occupants can be significantly improved [7,8] in both domestic and commercial buildings by the decreasing of the indoor temperature on the one hand, and the smoothing of the thermal fluctuations on the other one [9].…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. a b s t r a c tThis paper deals with an experimental study of Phase Change Materials (PCMs) by DSC and focuses particularly on the influence of PCMs damage on their thermodynamic properties. First, different series of tests were performed on non-damaged PCMs (reference) using different masses and heating rates in order to optimize the choice of the experimental parameters used in DSC test. Accordingly, the specific heats at solid, liquid phases and the latent heats of PCMs were obtained. In addition, a fast approximate approach was suggested for the determination of the heat capacity of PCMs from a direct exploitation of the heat flux curves obtained by scanning PCMs at different heating rates. Finally, damaged PCMs were investigated and their thermal properties (specific heat and phase change enthalpy) were compared to the reference PCMs. It was shown from the obtained results that low heating rates are more suitable for PCMs scanning during DSC measurements in order to ensure a thermodynamic equilibrium within the sample. Furthermore, the results highlighted that damage of PCMs can lead to the loss of their specific heat capacity of about 28% compared to the non-damaged PCMs.

“…[16,17] Microencapsulated phase change materials (MePCMs), a typical microcapsule with phase change material (PCM) as a core, have received a growing attention in the energy aspect in recent years, [18,19] because microencapsulation can tolerate volume change of PCM, increase heat transfer efficiency, enlarge heat transfer area, and reduce PCM reactivity with outside moieties. These features make MePCMs functional in many applications, such as temperature regulation, [20,21] energy-saving materials, [22] solar energy utilization, [23] and heat transfer. [24] Although heat storage or release relies on core material, the shell material of MePCMs plays an important role in the performance of MePCMs.…”

a Microencapsulated phase change materials (MePCMs) using melamine-formaldehyde resin/SiO 2 as shell were investigated in this paper. Organically modified SiO 2 particles were employed to stabilize Pickering emulsion, and in situ polymerization of melamine and formaldehyde was carried out to form hybrid shell. The performances of resultant MePCMs with hybrid shell were investigated comparatively with the MePCMs with polymer shell. SiO 2 particles raise the microencapsulation efficiency by improving the stability of emulsion and providing a precipitation site for melamine-formaldehyde resin. Also, the mechanical strength, thermal reliability, and anti-osmosis performance of MePCMs were improved significantly by SiO 2 particles in the shell. Our study shows that Pickering emulsion is a simple and robust template for MePCMs with polymer-inorganic hybrid shell.

“…Instead the PCM stays safely with the shell at all times, preventing leakage and also preventing any off-gassing during melting. In this study [23], the PCM capsules were combined with gypsum powder and glass fiber to form gypsum boards by compression molding. The PCM was octadecane with a melt range of 26-28 °C.…”

Thermal Energy Storage Using Phase Change Materials

As discussed in Chap. 1, energy storage through solid-liquid phase change is inherently a transient process and is best suited for systems that experience repeated transients, such as on-off or periodic peaking cycles, or for those systems which require thermal energy storage for later use. PCMs are commonly used in applications for both thermal management and for thermal energy storage.Interest in PCMs for thermal management of systems can be traced back at least through the 1970s. NASA in particular was interested in the use of PCMs as what were then referred to as "thermal capacitors" and PCMs were implemented in several moon vehicles and in Skylab [1]. The 1977 NASA tech brief "A Design Handbook for Phase Change Thermal Control and Energy Storage Devices" [2] was one of the first comprehensive PCM references, and is still widely cited and used today.During the 1970s and 1980s, interest was also building in the application of PCMs in solar systems [3-5] for thermal energy storage in both large solar plants, and in smaller domestic applications such as domestic hot water systems. The concept of embedding PCMs in various types of building materials, such as wallboard and floorboards, in order to create houses and offices with lower heating and cooling loads for greater energy efficiency, also began in the 1970s/80s [6,7]. Simultaneously, a significant amount of fundamental research was being completed on PCMs, considering in-depth the melting and solidification processes, and the roles of conduction and natural convection on the phase change processes [8][9][10][11].With the growth of computing power through the 1980s and 1990s, integrated circuits began dissipating significant amounts of heat and PCM applications in the thermal management of high performance, military and consumer electronics came on the scene in the late 1990s [12][13][14]. More recently, PCMs have seen application in textile design for energy absorbing clothing for military and consumer products [15].
