Thermosolar technology is being inserted gradually in industrial activities. In order to reach high energy efficiency, thermosolar can be linked to heat pump technology, combining more efficient conventional and renewable energy support for processes. Their integration in complex processes can...

Environmental awareness increases, with demands for environmental certifications of new communities and buildings as a result. In the district heating industry, enabling of decentralized energy production is one way to meet requirements from customers. In this paper the technical impact of...

In this paper, a reliable and cost-effective polygeneration system for an existing test building, able to provide electricity, cooling and heating needs is presented, modelled and assessed. The system relies on solar energy as the primary source (PV and solar thermal collectors). Building...

Chile has one of the best worldwide conditions for the generation of electrical energy from solar resources, having an annual average Direct Normal Irradiation (DNI) of 9–10kWh/m2/day. Many important astronomical observatories have been installed in the north of Chile because of the low number...

An exergy analysis was performed to compare a conventional (1) two panel photovoltaic solar thermal hybrid (PVT x2) system, (2) side by side photovoltaic and thermal (PV+T) system, (3) two module photovoltaic (PV) system and (4) a two panel solar thermal (T x2) system with identical absorber...

With a strong industrial base and successful commercialisation of technologies in renewable energy, India is in a position today to offer state-of-the-art technology to other developing countries and is poised to play a leading role in the global movement towards sustainable energy development....

The performance of a novel heat exchanger unit (‘Solasyphon’) developed for a solar hot water system was experimentally investigated under indoor and outdoor operating conditions. The ‘Solasyphon’ can be easily integrated to an existing single-coil hot water cylinder avoiding the need...

This paper presents the results of an experimental study conducted on a multi-tank thermal storage for solar hot water heating applications. The purpose of the study was to investigate the thermal behaviour of the stratified tank system when subjected to constant temperature charging and...

Analytical models for the prediction of the heat loss from the top cover of single and double glazing flat plate solar collectors have been proposed. The models require no iteration to solve and therefore, are easy to use. The models allow the analysis of collectors with very small air gap...
