“…reaches its maximum when the 0.5 K min À1 transition peak is completely subsided. This clearly learns that PCMs should be not be measured at the conventional high rates, a conclusion shared with the authors of Reference [17].…”

“…Whereas DSC experiments typically are performed at 10 K min À1 (although lower rates are recommended for experiments with PCMs [1,16,17,40]), ASC experiments are typically performed at a few K h À1 away from the transitions. But this disadvantage is offset by the higher resolution of the ASC data and the fact that a complete understanding of a sample from DSC experiments requires in principle runs at several rates.…”

“…In our view, while a DSC gives a useful first picture of a phase transition, high-quality data cannot be obtained with it. This is realised by researchers in the field of PCMs [15,16], and careful DSC use [17] and improved analysis of DSC data [18,19] have been proposed.…”

The correct determination of the phase transition behaviour of phase change materials (PCMs) is paramount for assessing their application potential. In this work, the merits of a novel calorimetric technique, Peltierelement-based adiabatic scanning calorimetry (pASC), for PCM characterisation are investigated, especially in comparison with the commonly-used differential scanning calorimeter (DSC). A comparative study of two alkanebased PCMs, the commercial mixture RT42 and the pure alkane tricosane (C23) with these two techniques shows that pASC provides data at much higher resolution than DSC, due to its operation in thermodynamic equilibrium. Specifically the rate-dependence and deformation that is inherent to DSC experiments is absent in pASC. In addition, the enthalpy of the PCM is directly obtained. pASC results easily conform to the accuracy limits that are proposed in literature for the transition temperature and storage capacity of PCMs.

“…It complies with the typical standards used in DSC analysis, but it did not follow the advices of Lazaro and Dumas [39] who recommended a slow heating rate for the PCM sample to be able to reach phase equilibrium in both thermal and chemical aspects. Nevertheless, the heating and cooling rate applied in the presented work can be considered as adequate for the tested materials.…”

Phase change materials (PCM) are used in many industrial and residential applications for their advantageous characteristic of high capacity of latent thermal storage by means of an isothermal process. In this context, it is very useful to have predictive mathematical models for the analysis of the thermal performance and the thermal design of these layers. In this work, an experimental validation of an analytical model that resolves the steady periodic heat transfer problem in a finite layer of PCM is presented. The experimental investigation was conducted employing a PCM with thermophysical and thermochemical behavior very close to those hypothesized in the formulation of the analytical model. For the evaluation of the thermophysical properties of the PCM sample used, an experimental procedure created by the authors was employed. In all tests realized in a sinusoidal and non-sinusoidal periodic regime, the comparison between the measured and calculated trends of the temperature at different sample heights and of the surface heat fluxes show an excellent agreement. Moreover, also having verified the analytical total stored energy, the analytical model constitutes a valid instrument for the evaluation of the latent and sensible contribution and the trend in time of the position of the bi-phase interface.
