    Abstract: In order to solve the heat dissipation problem of densely-packed solar cells in high concentration photovoltaic (HCPV) system, a new cooling method of using silicon oil directly immerse the solar cells was proposed. The heat transfer performance of silicon oil immersion cooling the densely-packed solar cells with and without fin structure was inves... Show More

    Abstract: This paper presents several models and implementations on measuring the thermoelectric behaviour of an unknown material using Matlab/Simulink. The proposed models are designed using Simulink block libraries and can be linked to data obtained from an actual experimental setup. This model is unique, as it also contains an implementation that can be u... Show More

    Abstract: A number of studies have shown that feedback on users’ own energy consumption can be effective in reducing household energy consumption. Almost all the studies on presenting energy feedback relate to in-home displays and domestic environments, only a few concern other contexts. Building automation systems in modern office buildings collect a large ... Show More
