Title: Preparation of fine powdered composite for latent heat storage

Abstract

Application of latent heat storage building envelope systems using phase-change materials represents an attractive method of storing thermal energy and has the advantages of high-energy storage density and the isothermal nature of the storage process. This study deals with a preparation of a new type of powdered phase change composite material for thermal energy storage. The idea of a composite is based upon the impregnation of a natural silicate material by a reasonably priced commercially produced pure phase change material and forming the homogenous composite powdered structure. For the preparation of the composite, vacuum impregnation method is used. The particle size distribution accessed by the laser diffraction apparatus proves that incorporation of the organic phase change material into the structure of inorganic siliceous pozzolana does not lead to the clustering of the particles. The compatibility of the prepared composite is characterized by the Fourier transformation infrared analysis (FTIR). Performed DSC analysis shows potential of the developed composite for thermal energy storage that can be easily incorporated into the cement-based matrix of building materials. Based on the obtained results, application of the developed phase change composite can be considered with a great promise.

  • A method of three-dimensional numerical calculation is proposed to obtain the performance of a finned-tube-type latent heat thermal energy storage unit, and the validity of the calculations was checked by comparing the calculated results with experimental ones. In this article calculations have been carried out to examine the effects of various parameters appearing in the governing equations on the heat transfer in the solidification process, and the range of these parameters in which the fin effects are significant is examined.
  • The effective utilization of a focus mounted parabolic dish Stirling solar power conversion unit is favored by the use of heat pipe thermal transport and latent heat thermal energy storage (TES). Such a system has been designed and is being fabricated for test. A modular simulation of the thermal transport and storage of this system has been tested at different operating angles, power levels and time periods appropriate to that design. 7 refs.
  • Effects of the configuration of a finned tube on the heat transfer characteristics of a latent heat thermal energy storage (LHTES) unit have been studied experimentally and theoretically. As a result, it is shown that the performance of the unit is almost the same for the finned tubes with the same surface area even if the fin configuration is quite different. Calculated results of heat fluxes for the two types of finned tubes, each of which has lateral fins or +-arranged longitudinal fins, are in good agreement with the experimental data, which confirms the validity of the calculations.
  • The applicability of the similarity rule that the relationship between the similarity function and the frozen fraction is independent of the Biot number is known to have a connection with the uniformity of heat-flux distribution on a heat-transfer surface. A latent-heat thermal-energy storage unit with straight fins, which has the nature of losing such uniformity inherently, has been adopted to examine how the applicability of the similarity rule will be affected by the thickness and thermal conductivity of the heat-transfer tube serving as the base of the straight fins. It is proved that, if the heat-transfer tube is made ofmore » a high-thermal-conductivity material, the applicability of the similarity rule can be ensured over wide variations in the thickness of the tube. On the other hand, if the heat-transfer tube has a lower thermal conductivity, the similarity rule is valid only in the situation in which the tube is considerably thick. The temperature distribution inside the storage unit, as well as the position of the solid-liquid interface, is shown for the purpose of discussing the results.« less
  • This paper deals with thermal properties of an oil (tetradecane, C{sub 14}H{sub 30}, melting point 278.9K)/water emulsion as a latent heat-storage material having a low melting point. The measured results of the physical properties of the test emulsion, that is, thermal conductivity, specific heat, latent heat, and density, are discussed for the temperature region of solid and liquid phases of the dispersion material (tetradecane). It is clarified that Eucken`s equation can be applied to the estimation of the thermal conductivity of the emulsion. Moreover, it is established that tetradecane as the dispersion material exhibits a supercooling phenomenon which influences themore » thermal properties. Useful correlation equations of the thermal properties for the emulsion were proposed in terms of temperature and concentration ratio of the emulsion constituents.« less
