dc.description.abstract | In high-energy-demand regions, such as the Arctic, the building sector is focused on reducing the carbon footprint and
mitigating environmental impact. To achieve this, phase change materials (PCMs) are being investigated for thermal energy
storage due to their high latent heat of fusion. However, their limited applications arise from poor thermal conductivity. In
addressing this issue, the research delves into the preparation and characterization of nano-PCMs. These materials, synthesized in a laboratory setting, exhibit enhanced thermal performance compared to pure PCMs, attributed to the incorporation
of nanoparticles in the material composition. Therefore, in the study, three paraffins with different melting temperatures (10,
15 and 18 °C) are modified by incorporating titanium oxide at various concentrations (0.05, 0.1, 0.2 and 0.5 mass%). Thermal
conductivity and latent heat capacity measurements were undertaken using a thermal conductivity measuring apparatus and
differential scanning calorimetry, respectively. The aim was to evaluate the enhanced performance of the modified PCMs
in comparison with pure PCMs and to assess their suitability for cold climate regions. Results showed that nanoparticle
incorporation increased thermal conductivity by up to 37%, albeit with a slight reduction in latent heat capacity of up to 12%.
Among the samples, RT18 exhibited the most significant improvement in thermal conductivity, while RT10 experienced a
minor decrease in enthalpy values. Ultimately, RT10 was identified as the optimal PCM option for cold climates, as its phase
change temperature range aligns with the outdoor temperatures in the Arctic. | en_US |
