The warm draft that floats from the window has an unfavorable influence on indoor thermal comfort condition, which heated air temperature. Therefore, integrated cooling system combined novel free-suspended ceiling radiant panel (CRCP) with a wall Attached Ventilation (WAV) is proposed and investigated by using three-dimensional conjugated computational fluid dynamic (CFD). Two different WAV systems (ceiling inlet/ceiling outlet; inlet/floor outlet) are examined under various operating...
A concise critique on harnessing the abundant solar thermal energy and improvement with vacuum insulation for utilization conversion is presented. This research implicates that world becoming a global smart city prompted by increasing daily demand of population land-use. Amongst all renewable resources available, collectors (STC) are most copious because it accessible in both direct indirect modes capacity operation 2019 was 479 GWth annual yield estimated to be 389 TWh. Hybridization has...
New small-scale experiments are carried out to study the effect of groundwater flow on thermal performance water ground heat exchangers for source pump systems. Four exchanger configurations investigated; single U-tube with circular cross-section (SUC), an oval (SUO), and spacer (SUC + SSC) (SUO SSC). The soil temperature distributions along horizontal vertical axis measured recorded simultaneously measuring electrical energy injected into fluid, borehole wall is as well; consequently,...
A zero-energy building (ZEB) requires an innovative integration of technologies, in which windows play a paramount role energy reduction, storage, and generation. This study contributes to four designs sliding smart windows. It integrates air-gap (AG), phase change material (PCM), photovoltaic (PV), vacuum glazing (VG) technologies. These are proposed generate electricity along with achieving efficient thermal insulations heat storage simultaneously. two-dimensional multiphysics model that...
Photovoltaic–thermal (PV/T) solar collectors convert radiation into electrical power and heat.
In the high concentrator photovoltaic (HCPV) systems with solar concentration ratios up to 2000 Suns, significant heat is generated in used cell layer. This requires an efficient and smart cooling technique keep it operating at a safe temperature. this paper, another ultra-high (UHCPV) system smaller area of 1 mm2 ratio (CR) 10,000 Suns proposed. simple passive even CR. The optimal dimensions method using spreader are defined. A 3D thermal model for multijunction coupled multi-objective...
In this study, a new design of photovoltaic thermal (PV/T) collector is proposed. This uses vacuum layer above the silicon wafer and not exists in traditional PV/T collector. used to decrease heat loss from top surface The analysis conducted using 3D modeling. with achieved 26.6% increase power while keeping electrical same at Reynolds number 50 solar radiation 1000 W/m2. addition, degradation pressure slightly influence performance increasing 0.01 Pa 10 Pa. While further 1.013×105...
The radiant ceiling cooling panel (RCCP) system has been proved thermally efficient and economically but it cannot prevent hot air stream from window individually. Therefore, this study integrated a forced ventilation with new RCCP segmented concave surface. In study, three-dimensional CFD model is developed validated the experimental results. Whereas, indoor thermal comfort performance of proposed coupling are numerically investigated, analyzed, compared ventilation. results show that...
