Abstract

Increasing use of renewable energy contributes to sustainable energy production by reducing the negative effects of greenhouse gases and carbon emissions. Due to the ease of use and ubiquity of solar energy, it is attractive amongst renewable sources of energy. The biggest problem of solar energy technologies, however, is not being able to benefit from sunlight for 24 hours. Nonetheless, this problem can be eliminated thanks to the storage of solar thermal energy. The utilization of phase change material-based heat transfer fluid is directly heated by the solar radiation in this study. The phase change material is encapsulated by the different types of nanoparticles and dispersed in pure water. The Discrete Ordinate Method is applied as a radiation model in order to analyse the impacts of the absorption, scattering, and emitting factors. The results reveal that the capacity of the heat transfer fluid to capture solar energy enhances with the addition of encapsulated phase change material to the water. Therefore, the temperature gain and stored energy of the phase change slurry increases more than the pure water. The energy storage is also augmented by improving the mass concentration of the phase change material. However, the size of the core/shell capsules augments with increasing shell thickness, affecting the thermal barrier between them and the heat transfer fluid. This reduces the heat that the PCM can absorb and lowers the temperature of the system. As a result, this work clearly states that because the phase change material based latent functional heat transfer fluid is used as a storage medium and as a working fluid, the thermal performance of the solar collector is further enhanced.
