Abstract  

Isothermal titration calorimetry (ITC) and reaction calorimetry (RC) have been used to construct the solid-liquid equilibrium line in ternary systems containing the solute to precipitate and an aqueous mixed solvent, and to study polymerization reactions under real process conditions, respectively. Phase diagrams have been established over the whole concentration range for some benzene substituted derivatives, including o-anisaldehyde, 1,3,5-trimethoxybenzene and vanillin, in {water + alcohol}mixtures at different temperatures. Acrylamide polymerization in aqueous solution using potassium permanganate/acid oxalic redox system as initiator was investigated on a homemade calorimeter, which works according to the isoperibolic mode. A Calvet type differential RC was used to illustrate the applicability of temperature oscillation calorimetry (TOC) for the evaluation of the heat transfer coefficient during the course of reaction.

The efficiency of photovoltaic modules and their performance depends on the value of irradiation and on the temperature of the module. The temperature of the modules can be reduced with the suitable set-up of the modules giving an opportunity to the natural (buoyancy driven) flows for cooling the PV modules. Present work is aimed at defining the heat transfer coefficients of the modules, using the methods of the computational fluid dynamics. The heat transfer coefficients are defined at the typical placements of modules and in the case of average wind speeds typical in Hungary. Such values could be used to define the accurate working temperature.
