“…The addition of PBPCM reduces this thermal property by 76–79% compared to the reference plaster, thus demonstrating the insulating effect induced by PCM incorporation. These findings are consistent with those reported in ref, which show that the addition of PCM to plaster decreased the thermal conductivity from 0.54 W m –1 K –1 for the reference sample (without PCM) to 0.25 W m –1 K –1 for plaster incorporating 30% PCM.…”

This study aims to explore the effects of augmenting the mass proportion of a composite comprising paraffin and beeswax (PBPCM) within plaster, which influences the thermal insulation of a dual wall. This work is primarily based on the thermal properties of the composite material PBPCM/plaster with varying percentages of PBPCM. Various essential parameters, such as density, thermal conductivity, specific heat capacity, thermal diffusivity, and latent heat, were assessed and juxtaposed with those of conventional plaster for the PBPCM/plaster composite material. The evaluation of this composite material was executed through an experimental device on a laboratory scale. The obtained results show that the increase in the mass fraction of PBPCM in the plaster decreased the thermal conductivity of plaster more than 3 times, whereas this increase of the PBPCM fraction in plaster enhances heat retention, specifically in specific heat capacity under constant conditions. Nevertheless, in a dynamic state, thermal effusivity has the lowest value for 50% PBPCM. The recommendation is to utilize 50% PBPCM, as it yields an optimal thermal effusivity, and significant values of specific heat capacity and latent heat have been noted for this percentage of PBPCM, measuring 1263.77 kJ/kg K and 18.9 kJ, respectively. Additionally, an increase in the PBPCM percentage narrows the temperature range suitable for effective thermal energy storage.

“…The incorporation of PCM can be carried out through different techniques [43] such as encapsulation (microencapsulation [20,24,32,[44][45][46][47][48][49][50] and macroencapsulation [27][28][30][31]), immersion [34][35], stabilized form [33] and direct incorporation [23,25].…”

“…Another method is a separate PCM layer, located on the inside or outside of the ceramic partition [11,12] or between the partition layers [13]. Research is also carried out on the modification of phase change material for products used as indoor interior cladding [14][15][16]. The purpose of this modification is to absorb excess heat energy inside the room, originating, inter alia, from solar radiation energy passing through significant glazed surfaces of the building or the operation of devices inside the room.…”

The article presents a comparative analysis carried out using three methods, determining the heat transfer coefficient U for a ceramic product modified with a phase change material (PCM). The purpose of the article is to determine the convergence of the resulting thermal characteristics, obtained using the experimental method, numerical simulation, and standard calculation method according to the requirements of PN-EN ISO 6946. The heat transfer coefficient is one of the basic parameters characterizing the thermal insulation of a building partition. Most often, for the thermal characteristics of the partition, we obtain from the manufacturer the value of the thermal conductivity coefficient λ for individual homogeneous materials or the heat transfer coefficient U for the finished (prefabricated) partition. In the case of a designed composite element modified with a phase change material or other material, it is not possible to obtain direct information on the above parameter. In such a case, one of the methods presented in this article should be used to determine the U factor. The U factor in all analyses was determined in stationary conditions. Research has shown a significant convergence of the resulting value of the heat transfer coefficient obtained by the assumed methods. Thanks to obtaining similar values, it is possible to continue tests of thermal characteristics of partitions by means of numerical simulation, limiting the number of experimental tests (due to the longer test time required) in assumed different partition configurations, in stationary and dynamic conditions.
