Wet-collector systems, designed and operated for air-pollution control without concern for or con­ sideration of the stream-pollution effects of their liquid-borne wastes, may cause significant localized pollution of surface and ground water bodies. Wet­ collector systems can be designed with presently known technology to decrease contaminants in effluent outfalls to acceptable levels. Increasi...

Jet impingement cooling has been utilized to improve the performance of solar energy technologies such as collectors, PV systems, PVT and CPV systems. This article provides an overview current systems using jet impingement. The distinctions between each study, research results system design, are examined contrasted. summary demonstrates that collectors most widely technology owing their direct ...

The overall heat loss coefficient (U-value) of a vacuum tube solar collector is investigated experimentally and theoretically with regard to the pressure of the remaining gas inside the evacuated glass envelope. A number of collector tubes of same geometry are randomly selected from an installation of a solar based air-conditioning system and tested individually in the laboratory for the determ...

Photovoltaic-thermal (PVT) collectors are hybrid solar that convert and ambient energy into thermal electrical energy. Integrated PVT-HP, in which PVT combined with a heat pump, offers an efficient renewable option to replace conventional fossil fuel-based systems residential buildings. Currently, system concepts the selection, design control of components aligned towards performance lacking. T...

Silicon based photovoltaic modules (PV) are a wide spread technology and used for small large PV power stations. At the moment, most efficient method which can be to improve annual electrical energy production of PVs is solar tracking systems. However, systems increase substantially initial cost investment insert maintenance costs. During last few decades, alternative improving methods have bee...

This paper presents an experimental investigation of a photovoltaic-thermal solar collector (commonly known as PVT) that generates both electricity and heat from the same gross area. PVT collectors, in theory, achieve higher combined electrical yields. Additionally, enables thermal coupling between PV cells transfer cooling medium. Electrical outdoor testing measurements have been performed on ...

The influence of recycling on double-pass solar air collectors with welding of the V-corrugated absorber has been studied experimentally and theoretically. Welding the V-corrugated absorber and the recycle-effect concept to the solar air collector was proposed to strengthen the convective heat-transfer coefficient due to turbulence promotion. Both the recycle effect and the V-corrugated absorbe...
