Analysis of the physical stability of PCM Slurries
International Journal of Refrigeration, 2013Co-Authors: Monica Delgado, Javier Mazo, Conchita Peñalosa, Ana Lazaro, Bel n ZalbaAbstract:Microencapsulated phase change material slurry (mPCM slurry) is a latent heat storage fluid in which the PCM microparticles have been dispersed in water. One of the main issues to be tackled is its lack of physical stability, since stratification problems tend to occur. Generally, an unstabilization process in PCM Slurries can take weeks or even months. To predict the physical stability of PCM Slurries without having to wait so long, a methodology well known in the food and pharmaceutical fields has been applied. This methodology basically consists of measuring samples with a rheometer in oscillatory mode. These measurements can be related to visually obtained measurements of the unstabilization process of creaming, specifically with the creaming percentage over time. From the frequency sweeps accomplished, an exponential relationship between the creaming percentage and the elastic module of the PCM Slurries have been obtained. From the strain sweeps, the cohesive energies of the PCM Slurries have been calculated and related to the creaming percentage, observing a linear relationship. In this way, the dominant parameters in the unstabilization process have been obtained which manufacturers can modify in order to improve the physical stability of PCM Slurries. © 2013 Elsevier Ltd and IIR.

Review on phase change material emulsions and microencapsulated phase change material Slurries: Materials, heat transfer studies and applications
Renewable and Sustainable Energy Reviews, 2012Co-Authors: Monica Delgado, Javier Mazo, Ana Lazaro, Bel n ZalbaAbstract:Phase change materials (PCM) in the form of Slurries have had an increasingly important role as heat transfer fluids and as thermal energy storage media. Although it is a recent technology in the field of thermal energy storage with phase change materials, the volume of literature begins to be significant. This investigation carries out a compilation of information on two latent thermal fluids: PCM emulsions and microencapsulated PCM Slurries (mPCM Slurries). This review presents tables containing information on the different PCM emulsions and mPCM Slurries studied by different researchers, as well as commercially available products. Thermophysical and rheological properties are analyzed, making a special effort to analyze heat transfer phenomena, concluding with the enumeration of application examples available in literature. © 2011 Elsevier Ltd.

review of cold storage materials for air conditioning application
International Journal of Refrigeration-revue Internationale Du Froid, 2012Co-Authors: Gang Li, Yunho Hwang, Reinhard RadermacherAbstract:Abstract This paper reviews the recent development of available cold storage materials for air conditioning application. According to the type of storage media and the way a storage medium is used, water and ice, salt hydrates and eutectics, paraffin waxes and fatty acids, refrigerant hydrates, microencapsulated phase change materials/Slurries and phase change emulsions are separately introduced as suitable energy storage or secondary loop media. Water storage and static ice storage, which are already well-established technologies, have little need for further study. Dynamic ice slurry application is discussed especially for its generation method, relating to the efficiency and reliability of converting water or aqueous solution to ice crystals or ice slurry. Thermal and physicochemical properties of different phase change materials have been summarized including latent heat, thermal conductivity, phase separation, supercooling, and corrosion. Moreover, corresponding solutions for issues of different materials are also discussed. Thermal and hydraulic characteristics of phase change Slurries (mainly about clathrate Slurries, microencapsulated phase change Slurries, and phase change emulsions) are discussed and summarized. In addition, the principle of the sorption cold storage is described and different kinds of working pairs are introduced. Relevant perspectives for commercialization of storage materials are discussed.
