Abstract The photovoltaic module (PV) consists of many cells made silicon that lose their properties with an increased temperature. Increasing cell temperature represents intrinsic problem causes a drop in the open-circuit voltage PV module, thus affecting its performance. present work investigates using evaporating cooling as passive technique to absorb generated heat from and lower by cotton ...

Wind is a significant factor in the thermoregulation of chicks of shorebirds on the Arctic tundra. We investigated the effect of wind at speeds typical of near-surface conditions (0.1-3 ms(-1)) on metabolic heat production, evaporative cooling and thermal conductance of 1- to 3- week-old downy scolopacid chicks (least sandpiper Calidris minutilla; short-billed dowitcher Limnodromus griseus; whi...

Direct evaporative cooling is widely known for being an energy efficient air conditioning solution arid and/or semi-arid climates. Commercialized pads vary in material and construction characteristics, while existing research proposes several alternative wetted media configurations. The most studied factors on the operation are velocity or mass flow rate, psychrometric conditions; pad thickness...

Cooling is a common phenomenon in daily life. Among different means of cooling, evaporative cooling through the evaporation liquids prominent method, for it removes large quantities heat. Our prompt aimed at evaluating impacts parameters on speed cooling. We evaluate degree impact by experiment and simulation experiments with finite element software COMSOL, using containers shapes, wind speeds,...
