The Parabolic Trough Collector (PTC) is the most common type of high-temperature solar thermal technology, in which the heat transfer fluid is usually synthetic oil, molten salt or water/steam. Experiences in existing plants have shown some operating problems with all these types of fluid, which...

A description of the first solar village project in Syria is given. The Abou-Sorra electrification project supplies power to six households. The nominal power of the solar array is 3.6 kWp. The installation was set up in March 1994 by the Higher Institute of Applied Science & Technology (HIAST)....

Two modifications for solar desalination systems are presented. The first modification, using a packed layer that installed in the bottom of the basin to increase the efficiency of the still. A packed layer is formed from glass balls which is considered as simple thermal storage system. The...

The transformation of the energy industry towards a more sustainable production of electricity increases the importance of distributed generation from renewable sources such as solar photovoltaic (PV). German utilities have largely failed to benefit from this development and lost 97% of the...

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...

Theoretical analysis of a solar energy-powered Rankine thermodynamic cycle utilizing an innovative new concept, which uses supercritical carbon dioxide as a working fluid, is presented. In this system, a truly ‘natural’ working fluid, carbon dioxide, is utilized to generate firstly...

Solar energy is recognized as one of the most promising alternative energy options. On sunny days, solar energy systems generally collect more energy than necessary for direct use. Therefore, the design and development of solar energy storage systems, is of vital importance and nowadays one of...

Employing solar energy for house heating is investigated in this paper for a typical house in the West Bank Collector area is optimized based on minimum annual heating cost. TRNSYS program was used for solar house simulation. For a typical house heating load in the West Bank a flat plate...

In this study, a novel dual-nozzle ejector enhanced vapor-compression cycle (DEVC) for solar assisted air-source heat pump systems is proposed. In DEVC, the use of the dual-nozzle ejector for recovering the expansion losses is a very promising approach to improve the cycle performance. A...

This work presents a new design of an air conditioning prototype by solar energy developed at the Laboratory of Electromechanical Systems of the National Engineering School of Sfax, Tunisia. The new conception permits to produce heat or cold by using solar energy without polluting the...
