Many research and significant worldwide efforts have been made to combat climate change. The purpose of this research was to maximize the productivity of a flat-plate hybrid collector with two kinds of cooling medium, namely water and water-based Al2O3 nanofluid. Effects of single-volume concentration (0.1%) of Al2O3 nanoparticles and four types of volume flow rates such as 0.5, 1.0, 1.5, and 2.0 litres/minute (LPM) were also examined which found that the best performance is achieved with 2.0 LPM. The experimental results found that the hybrid collector significantly depends on solar radiation, the surface geometry of the cooling channels, and the volume flow rates of the working medium. In addition, the performance of the hybrid collector improved with increasing volume flow rate. Maximum glazing surface temperature has been attained by water collector was 68.2°C, whereas water-based nanofluid has achieved its glazing surface temperature 63.8°C. As a result, the life of the solar panel has been increased significantly. This occurred because an increase in the volume flow rate increased the turbulence of the working medium, thus resulting in better performance of the hybrid collector. Besides, the results also showed that the distribution of working medium in the channel had played a major role in the heat transfer rate. The thermal efficiency was found to vary from 13.9% to 60.7% for all the four-volume flow rates of water. Similarly, thermal efficiency was attained from 16.8% to 79.4% for all the four-volume flow rates of Al2O3 nanofluid.

“…The used parameters for the PV production component are listed in Table 3. 1200 [40,41] Thermal storage was modeled as a water tank sensible heat storage, as the other alternative, phase change material (PCM) latent heat storage, is not yet technologically mature enough. Furthermore, the available cost and life cycle emission data of PCM storages is scarce and uncertain.…”

Case Study and Feasibility Analysis of Multi-Objective Life Cycle Energy System Optimization in a Nordic Campus Building

Due to the high energy consumption of buildings, there is a demand for both economically and environmentally effective designs for building energy system retrofits. While multi-objective optimization can be used to solve complicated problems, its use is not yet widespread in the industry. This study first aims to develop an efficient and applicable multi-objective building energy system optimization method, used to dimension energy production and storage retrofit components in a case campus building in Lahti, Finland. Energy consumption data of the building are obtained with a dynamic energy model. The optimization model includes economic and environmental objectives, and the approach is found to function satisfactorily. Second, this study aims to assess the feasibility and issues of multi-objective single-building energy system optimization via the analysis of the case optimization results. The results suggest that economically beneficial local energy production and storage retrofits could not always lead to life cycle CO2-eq emission reductions. The recognized causes are high life cycle emissions from the retrofit components and low Nordic grid energy emissions. The performed sensitivity and feasibility analyses show that correctness and methodological comparability of the used emission factors and future assumptions are crucial for reliable optimization results.
