A photovoltaic-thermal (PV-T) hybrid collector evaporator was designed and developed to produce electrical energy extract thermal simultaneously from the panel using refrigerant circulated tubes. The absorbs heat photovoltaic panels during its phase change liquid vapour. PV-T evaporators deliver both electricity outputs. An R-32 refrigerant-based solar-assisted pump water heating system with a ...

In photothermal energy conversion the absorbed solar flux is converted to heat which is then used directly or is converted to mechanical or electrical energy. Efficient receiver design requires that thermal losses from the absorber surface, which is the hottest element of the system, be minimised. Receivers are, in fact, generally classified according to their operating temperature ( I , 2). Th...

The main problem today is the shortage of energy and environmental pollution. These problems can be avoided by employing renewable energy schemes. The most common renewable energy resources include Wind Energy, Tide Energy, Solar Energy, Hydrogen Energy, Bio Energy, Terrestrial Heat Energy and Thermal Energy and so on. Pakistan is affluent in almost all these resources especially in Thermal Ene...

The food industry is responsible for supplying the demand of ever-increasing global population. chain one major contributors to greenhouse gas (GHG) emissions, and waste accounts one-third produced food. A solution this problem preserving crops, vegetables, fruits with help an ancient method sun drying. For drying agricultural marine products, several types dryers are also being developed. Howe...

Solar thermal collectors represent a widely used type of system for the conversion of solar energy. In order to produce selective coatings on aluminium substrates to be used as absorber plates in high efficiency solar collectors, nickel pigmentation was applied to anodically oxidised surfaces. Electrochemical dc methods are used to study the oxidation of aluminium as functions of the following ...

Heating and cooling (H/C) represent the largest share of energy consumption worldwide. Buildings are main consumers H/C, while renewable for H/C provision still represents a low percentage, 22.0% in 2019. Hybrid photovoltaic-thermal (PV-T) systems gaining increasing attention both research applications, as they generate electricity useful heat simultaneously. The relevance potential PV-T collec...

The conversion of sunlight into electricity has been dominated by photovoltaic and solar thermal power generation. Photovoltaic cells are deployed widely, mostly as flat panels, whereas solar thermal electricity generation relying on optical concentrators and mechanical heat engines is only seen in large-scale power plants. Here we demonstrate a promising flat-panel solar thermal to electric po...

The use of solar thermal systems (STSs) has recently reached a significant edge. increasing research on developing an alternative power supply for limiting fossil fuel usage and climate change are the driving forces STSs. current work explores recent progress in STSs’ applications, including PV/T or “photovoltaic/thermal” systems, zero-energy buildings, greenhouse pumping water, refrigerators, ...

In this paper, a solar-powered dehumidification window (SPDW), combining a conventional double-glazed building window with a solid desiccant packed bed and a photovoltaic panel, has been proposed to dehumidify the air supplied to a residential building in an energy-saving way. The solid desiccant packed bed was installed between the double layers of the residential window to achieve the compact...
