This paper presents the analysis of heat losses from the trapezoidal cavity receiver used in linear Fresnel reflector (LFR) system. The experimental studies are conducted under laboratory conditions that are specially designed for this purpose. The effects of parameters such as the temperatures...

An integral-type solar-assisted heat pump water heater (ISAHP) is designed and tested in the present study. The storage tank and the Rankine cycle unit are integrated together to make a more compact size. A thermosyphon loop is used to transfer the heat from the condenser to the water storage...

A conceptual design and performance of a dual-purpose solar continuous adsorption system for domestic refrigeration and water heating is described. Malaysian activated carbon and methanol are used as the adsorbent–adsorbate pair. The heat rejected by the adsorber beds and condensers during the...

Many international studies and experience have shown that solar thermal power plants are the most economic form of the solar electricity generation. Since such plants are based on the concentration of the solar radiation to achieve high temperatures necessary for the thermo-dynamic power plant...

The increased environmental awareness coupled with the recent changes in the oil prices triggered the necessity of focusing on effective management of energy systems. Global climate change has caused many people to consider ways of reducing greenhouse gases Renewable energy has become an...

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...

There is a global resurgence in solar thermal power across the world. This paper provides a transparent framework for calculating the cost of generated electricity from a concentrated solar power (CSP) plant and the internal rate of return on equity. The different factors contributing to the...

This paper is an attempt to determine the potential for solar water heating (SWH) in South Africa and the prospects for its implementation between 2010 and 2030. It outlines the energy market conditions, the energy requirements related to residential and commercial water heating in the country...

A techno-economic analysis has been performed for a coal-fired power plant retrofitted with Solvent-based Post-combustion Carbon Capture (PCC) technology which is partially supplied with thermal energy by solar thermal collectors. The plant is compared with a generic PCC plant where all the...
