  Title Review and selection of EPCM as TES materials for building applications Type
  Year 2019 Publication International Journal Of Sustainable Energy Abbreviated Journal Int. J. Sustain. Energy  
  Volume 38 Issue 6 Pages 561-582  
  Keywords Encapsulated phase change materials; building applications; thermal energy storage materials  
  Abstract In order to improve the thermal efficiency of building thermal energy storage (TES) systems, the feasibility of using encapsulated phase change materials (EPCMs) as heat storage media is analysed in this work. Specifically, the finite element method is used to perform thermal behaviour analyses of several EPCMs. These analyses include technical and economic assessments in order to identify the best combination of PCM and shell material, using as main parameters: thermal energy storage, heat transfer rate, materials cost, among others. The results show that EPCMs composed by Na2SO4 center dot 6H(2)O as PCM and covered by stainless steel highlight as TES materials.

  Title Thermo-mechanical analysis of copper-encapsulated NaNO3-KNO3 Type
  Year 2015 Publication Chemical Engineering Research & Design Abbreviated Journal Chem. Eng. Res. Des.  
  Volume 93 Issue Pages 224-231  
  Keywords Copper-encapsulation; Nitrate salts; Simulation; Phase change material; Thermal energy storage; Comsol Multiphysics  
  Abstract The present paper presents a numerical study to investigate and assess the heat transfer behavior of a copper and salt composite. A mixture of nitrates, KNO3-NaNO3, within a deformable spherical shell coating of copper will be used as an encapsulated phase change material, E-PCM. In the context of a thermo-mechanical analysis of this E-PCM, a simulation is proposed to determine its storage capacity and properties The melting, or solidification of the encapsulated PCM particles do not provoke cracking of the deformable shell.

  Title Latent heat storage with tubular-encapsulated phase change materials (PCMs) Type
  Year 2014 Publication Energy Abbreviated Journal Energy  
  Volume 76 Issue Pages 66-72  
  Keywords Heat storage; Latent heat; Phase change materials; Nitrate-PCM; Tube-encapsulation; Experiments  
  Abstract Heat capture and storage is important in both solar energy projects and in the recovery of waste heat from industrial processes. Whereas heat capture will mostly rely on the use of a heat carrier, the high efficiency heat storage needs to combine sensible and latent heat storage with phase change materials (PCMs) to provide a high energy density storage. The present paper briefly reviews energy developments and storage techniques, with special emphasis on thermal energy storage and the use of PCM. It thereafter illustrates first results obtained when encapsulating NaNO3/KNO3-PCM in an AISI 321 tube, as example of a storage application using a multi-tubular exchanger filled with PCM. To increase the effective thermal conductivity of the PCM, 2 inserts i.e. metallic foam and metallic sponge are also tested. Experimental discharging (cooling) rates are interpreted by both solving the unsteady-state conduction equation, and by using Comsol Multiphysics. Predictions and experimental temperature evolutions are in fair agreement, and the effect of the inserts is clearly reflected by the increased effective thermal conductivity of the insert-PCM composite. Application of Comsol to predict the mechanical behavior of the system, when melting and associated expansion increase the internal pressure, demonstrates that the pressure build-up is far below the Young's modulus of the AISI 321 encapsulation and that this shell will not crack (C) 2014 Elsevier Ltd.
