The energy and exergy-based analyses were performed to evaluate the performance of the PV/T PCM system in comparison to the regular PV module. A maximum reduction of 27% in module temperature was found at a water flow rate of 1 LPM. PV/T PCM system achieved th...
A special experimental set-up, based on the repetitive element of the panel, was built. The main goals of an experimental study were to examine the behavior of the panel in real conditions and as well as gathering data that could be used for validation of computational tools. An experimental...
In-depth analysis of the main technical and operational challenges in the future has been carried out, and the prospective development of more efficient TE-PCM system and its hybrid configurations are projected based on the current technological level....
The evaporation of the primary working medium is performed directly in the heat sources, for example: heat from the icing of liquids, heat from boiling black liquid of the solar collectors, waste heat from the heating system itself, waste heat from the use of hot water, waste heat from air...
Water coolingPHASE-CHANGESTILLPERFORMANCEBackground: The increase demand of water for irrigation and human activities leads to a global development of alternative methods to produce distillate water especially from sea. In this context, the use of solar distiller instead of the classic distillation ...
Hence, a hybrid PV/T-DXHP direct expansion HP system with phase change material (PCM) has been proposed in this study to provide a building’s needs, i.e., electricity, space cooling, PV cooling, and hot water. This research was conducted to find ways for homes and businesses to use ...
The natural convection of NEPCM inside a coaxial pipe has been researched by Ghalambaz et al. [12] According to their findings, 5% of NEPCM may increase the mean NuAvg by around 73% when compared to water. In a different research work, Ghalambaz et al. [13] examined the results of ...
According to results, at 0.77 kW/m2m2 heating input the maximum base temperature declined by 13.03% in 0.02 wt.% GNPs-NEPCM/copper foam case. At heating input of 1.54 kW/m2m2, the maximum base temperature reduction of 16% was observed in case of 0.02 wt.% GNPs-NEPCM/copper foam and...
The cooling technologies chosen should be reliable, easy to operate, and efficient in nature. Among the most studied cooling systems are heat pipe cooling, hydraulic water cooling, jet impingement cooling, liquid immersion cooling, micro-channel heat sink cooling, and thermo-photovoltaic system [8]...
The authors have previously proposed a PCM radiant floor-heating system—built using the wet construction method and employing hot-water circulation—which could potentially form the middle-story of an apartment house. In the proposed and extant studies, the authors propose a design and system ...
