  • Performance analysis on industrial refrigeration system integrated with encapsulated PCM-based cool thermal Energy storage system
    International Journal of Energy Research, 2007
    Co-Authors: M. Cheralathan, Ramalingam Velraj, S. Renganarayanan

    Abstract:

    Cool thermal Energy storage (CTES) is an Advanced Energy Technology that has recently attracted increasing interest for industrial refrigeration applications such as process cooling, food preservation and building air conditioning systems. An experimental investigation on the performance of an industrial refrigeration system integrated with encapsulated phase change material (PCM)-based CTES system is carried out in the present work. In the experimental set-up a vertical storage tank is integrated with the evaporator of the vapour compression refrigeration system. Effect of the inlet temperature of heat transfer fluid (HTF) on the temperature variation of the PCM and the HTF in the storage tank and the performance parameters namely average rate of charging, Energy stored, specific Energy consumption (SEC) of the chiller with and without storage system are studied in detail. The effect of porosity variation in the storage tank is also studied. A 1°C decrease in evaporator temperature results in about 3–4% increase in SEC and 1°C decrease in condensing temperature leads to 2.25–3.25% decrease in SEC. The range of HTF inlet temperature and porosity values for optimum performance is reported. Copyright © 2007 John Wiley & Sons, Ltd.

  • JES FOCUS ISSUE ON ELECTROCHEMICAL PROCESSING AND MATERIALS TAILORING FOR Advanced Energy Technology Energy & Chemicals from Renewable Resources by Electrocatalysis
    , 2014
    Co-Authors: M. Bellini, Manuela Bevilacqua, Massimo Innocenti, Alessandro Lavacchi, Hamish A. Miller, Jonathan Filippi, Andrea Marchionni, Werner Oberhauser, Lianqin Wang, Francesco Vizza

    Abstract:

    The selective production of chemicals from renewable resources with contemporaneous release of Energy is perhaps one of the most desired targets of sustainable chemistry. Here, we report an overview of our recent research efforts, where we have demonstrated that this can be achieved using renewable alcohols, by means of two electrochemical devices: direct fuel cells and electrolyzers .I n either case, an aqueous solution of the fuel in the anode compartment is oxidized on a nanostructured electrocatalyst that promotes selectively the partial oxidation of the anolyte with high stability and fast kinetics. We have found that anode electrocatalysts based on nanosized Pd particles, alone or promoted by Ni-Zn phases as well as by CeO2 or TiO2, are able to accomplish this goal in alkaline environment when used in conjunction with commercially available cathode electrocatalysts and solid or liquid electrolytes. In an electrolyzer, containing an anode electrocatalyst similar to that employable in a DAFC, the electrolyte may be either an anion exchange-membrane or a solution of an alkali metal hydroxide (NaOH or KOH, for example) and the alcohol is converted to the corresponding alkali metal carboxylate, while hydrogen gas is produced at the cathode upon water reduction.
