“…Recently, Shukla et al [30] carried out the thermal cycling tests for some organic and inorganic PCMs selected based on thermal, chemical and kinetic criteria shown in Table 1, and their results showed that organic PCMs tend to have better thermal stabilities than inorganic PCMs. Tyagi and Buddhi [31] conducted the thermal cycling test for calcium chloride hexahydrate and found minor changes in the melting temperature and heat of fusion, only about 1-1.5℃ and 4% average variation respectively during the 1000 thermal cycles. They recommend the calcium chloride hexahydrate be a promising PCM for applications.…”

Thermal energy storage with phase change materials (PCMs) offers a high thermal storage density with a moderate temperature variation, and has attracted growing attention due to its important role in achieving energy conservation in buildings with thermal comfort. Various methods have been investigated by previous researchers to incorporate PCMs into the building structures, and it has been found that with the help of PCMs the indoor temperature fluctuations can be reduced significantly whilst maintaining desirable thermal comfort. This paper summarises previous works on latent thermal energy storage in building applications, covering PCMs, the impregnation methods, current building applications and their thermal performance analyses, as well as numerical simulation of buildings with PCMs. Over 100 references are included in this paper.

“…Views of (a) the pelletised bed adsorber without and with the SWS-1L [118] and (b) the coated adsorber with the SWS-1L [117]. 1 There is a difference between latent heat storage and thermochemical storage based on CaCl 2 : a latent heat storage process involves melting and solidification while sorption and thermochemical storage processes involve desorption/dehydration and adsorption/hydration. Phenomenologically, the main difference is that the energy in a PCM is being stored and released as melting or crystallization enthalpy due to a transition between solid and liquid state, while the energy in the use as sorption or thermochemical energy storage is stored by breaking or reforming the interaction of the water molecules in the crystal structure or melt.…”

“…Among other applications, this material has been used practically in various phase change material applications [1], closed sorption processes [2], desiccant cooling or dehumidification [3,4], refrigeration [5], drying [6,7], water recovery or extraction from atmospheric air [8e10], sorption [11] and thermochemical energy storage [12]. Calcium chloride is also applied in association (composites) with other materials in order to improve their suitability for the above-mentioned applications.…”

“…However, the use of chemical methods for seasonal storage has not yet progressed beyond small systems (Allegrini et al 2015). Examinations have been published of novel solid-liquid micro-phase change materials for thermal storage in the form of microcapsules (Sari et al 2010) and alternative phase change materials like calcium chloride hexahydrate (Tyagi and Buddhi 2008).…”

The status and needs relating to the optimal design of community seasonal energy storage are reported. Thermal energy storage research has often focused on technology development and integration into buildings, but little emphasis has been placed on the most advantageous use of thermal storage in community energy systems. Depending on the composition and characteristics of a community, the most appropriate community thermal storage may differ from that for a single building. District energy systems usually link thermal users to cold supplies and/or heat supplies (e.g., solar thermal energy, geothermal energy from ground-source heat pumps or geothermal hot zones, industrial waste heat, thermal energy from cogeneration or trigeneration). It is demonstrated that the optimal integration of these technologies can be enhanced through the use of appropriate seasonal thermal energy storage and that community-level seasonal storage can facilitate the development of smart net-zero energy buildings and yield efficiency, economic and environmental benefits. Issues that need to be resolved to allow optimal solutions to be attained are described. Advanced tools are required for modeling, simulation, analysis, improvement, design and optimization, which incorporate advanced methods like exergy analysis. The most appropriate scale, number and type (e.g., sensible, latent, thermochemical) of thermal storages in a community need to be better assessed, and the appropriate time duration capacities for each determined in an optimal manner. This is particularly important since a combination of short-, medium-and long-term storage is sometimes required to yield the most benefits from community energy systems.
