"The scope of the project is the attenuation of fluid temperature oscillations by means of latent heat thermal storage. The phase change of matter at constant pressure is almost an isothermal process and it is associated with the transfer of huge amount of heat (latent heat). This phenomenon can be employed in order to attenuate oscillations of fluid temperature. The investigations will focus on the attenuation characteristics of latent heat thermal storage with regard to thermal properties of the thermal storage material (heat of fusion, thermal conductivity). The studied cases will include the step change of fluid temperature and the periodic changes of fluid temperature (square wave, sinusoidal). The attention will be paid to the attenuation characteristics of latent heat thermal storage for various amplitudes and frequencies of the fluid temperature changes."@en .

Experimental and numerical modelling has been applied. An attenuator with paraffin-based and PMC was prepared. The attenuator characteristics dependence upon amplitudes and frequencies has been derived. The results are applicable in other energy systems, e.g. with air as a heat carrier fluid."@en .
