“…For example, the use of solar energy, focused initially on electricity production, has shifted to many applications, such as industrial thermal generation, solar dryers for the agricultural sector, residential water and space heating [5]. The development of thermal energy storage technology allows for better economic value from solar thermal systems, reducing dependence on fossil fuels, which can then reduce pollution from the combustion process [6]. This technology can be developed for passive systems, such as energy materials for walls, floors and ceilings, and active systems, with a more comprehensive range of applications, especially for solar heating systems.…”

In this research, the development of a small-scale heat transfer gerotor pump with an advanced arrangement for high-viscosity and high-temperature fluids is described comprehensively. The small-scale pump design aims to meet the needs of modular components for industry and research, especially for small-scale heat transfer applications such as residential heating systems. VDI 2221 approach was used to construct an advanced gerotor pump with an internal reservoir unit that can generate additional pressure and minimize the slip factor, thereby increasing its volumetric efficiency. The developed small-scale pump was designed in a smart arrangement, which required fewer components than a typical heat transfer pump. This helps to reduce the maintenance of the pump and its components. Experimental tests were performed using a testing apparatus equipped with a heater, a control system using Pulse Width Modulation (PWM) adjustment, valves, pressure, and temperature gauges. The instruments in the apparatus test were used to control the flow rate and pump speed and monitor the temperature of the working fluid. The results of the experiment show that the advanced gerotor pump was able to deliver fluid with a viscosity of 307 ml/min and a temperature of up to 230 °C. The components arrangement minimizes the slip factor, which is mostly the main challenge of positive displacement pumps. The maximum slip coefficient of the advanced gerotor pump design is 0.095. The volumetric efficiency was in the range of 0.803–0.905 when the pump operated at 2,100 RPM and 230 °C. The experiment and analysis results show that the pump can be implemented for the actual application of the thermal system, for research and industry

“…TES also can be coupled into a biomass burner where residual heat from the combustion process can be extracted and stored in the PCM using a mantle burner [7]. To accommodate the storage capacity, various phase change materials are potentially applied in latent heat storage systems, including salt hydrates, organic and inorganic PCM [8]. Among various options of PCM, paraffin wax is the most common material for latent heat storage, especially for low-temperature systems.…”

The present work is specifically focused on the form stability of paraffin as a phase change material (PCM) through the addition of high-density polyethylene (HDPE). The aim of adding HDPE is to obtain a stable form of paraffin during the phase transition. Moreover, improving the performance of PCM leads to an advanced operation of the latent heat storage unit with an excellent charging duration and response time. The study uses HDPE at a ratio of 5 wt %, 10 wt % and 15 wt %. The results indicate significant differences between the form-stable PCM (FSPCM) and pure paraffin. For instance, the supercooling degree is decreased with the addition of HDPE, where paraffin has a supercooling degree of 8.01 °C while FSPCM with 15 wt % HDPE has a supercooling degree of 3.73 °C. The latent heat of fusion by adding 10 wt % and 15 wt % HDPE is slightly decreased by 1.85 %, which is much lower compared to adding 5 wt % HDPE, which reduces the latent heat of fusion by about 6.02 %. Adding HDPE leads to a faster charging process and a better response time during the discharging process. The charging rate is increased significantly by adding 15 wt % HDPE with a substantial increment of around 40 % with an average charging rate of 2.39 °C/min. The heat release during the discharging process is increased for FSPCM with 5 wt % HDPE where the temperature drops by more than 70 °C within 20 minutes. The findings indicate that adding HDPE contributed positively to reducing the supercooling degree and providing a steady phase transition. Thus, the heat exchange process of paraffin is more favorable, which improves the performance of the latent heat storage unit. Furthermore, the operation can be improved significantly by providing a faster charging and discharging process
