A solar thermal power system in the city of Thessalonica with the use of the Pinch method for entropy minimisation
The objective of this paper is to create a small power plant, (producing 2 MW annually), which will be using solar energy as a driving fuel. The system is made up of three sub-systems: a set of Solar Collectors (SCS), a Rankine power cycle and a Heat Exchanger Network (HEN). Two cases with variations in the operation of the solar collectors and the heat exchanger network will be examined. The ...

Performance evaluation of parabolic dish type solar collector for industrial heating application
From Indian perspective there is a large potential available for low cost solar water heating systems. The described system can instantly fulfil needs of hot water in industrial sector. This type of system can be used for heating boiler feed water, laundry applications and other steam generation applications. In general, concentrated solar collectors have high efficiency as compared to flat plate ...

Energy and exergy analysis of a solar–assisted heat pump space heating system for clear days
The studies over solar–assisted heat pump systems have been performed mostly on time periods when solar radiation is high. Therefore, this study focuses on performance analysis of a solar–assisted heat pump system which stores the energy during the clear day and uses it as a heat source of heat pump space heating system during the night. Energy and exergy analyses divided into two parts, which ...

Design, development and experimental investigation of a solar tunnel dryer for drying mushroom
A solar tunnel dryer was designed and fabricated with locally available materials having the cross sectional area of the entire tunnel 5400 ? 1700 mm. The half of the nearly air tight tunnel base was used as the flat plate air heating solar collector and the remaining half as a dryer. The drying air temperature could be easily raised by some 6-10?C above the ambient temperature at an air velocity ...

On rooftops worldwide, a solar water heating revolution
The harnessing of solar energy is expanding on every front as concerns about climate change and energy security escalate, as government incentives for harnessing solar energy expand, and as these costs decline while those of fossil fuels rise. One solar technology that is really beginning to take off is the use of solar thermal collectors to convert sunlight into heat that can be used to warm ...

Flat absorbers with trapezoidal cavity for Fresnel reflecting solar concentrator
The absorber is a very important component of the solar concentrating collector. The overall heat loss coefficient of the flat rectangular absorber and multi-tube absorber were studied experimentally. Both absorbers were coated with ordinary dull black paint. The heat loss coefficient was comparatively 4-11% lower in the case of round pipe absorber and increased with the absorber temperature in ...

Insulation Materials for Thermal Solar Collectors
Thermal solar collectors absorb sunlight to collect heat. The term thermal solar collector is often used in reference to a device for heating water, however the term also can be used for large power generating installations or non-water heating devices. Solar thermal collectors are extremely efficient at capturing solar radiation, which is mostly comprised of electromagnetic radiation on the ...

Energy and exergy analysis of a double–pass thermoelectric solar air collector
Analysis of energy and exergy has been performed for a double–pass thermoelectric (TE) solar air collector. The incident solar radiation heats up the absorber plate so that a temperature difference is created between the thermoelectric modules that generate a direct current. Only a small part of the absorbed solar radiation is converted to electricity, while the rest increases the ...

Solarthermal parabolic trough power plants with integrated storage capacity
Parabolic trough power plants use concentrated direct insulation for steam generation in a Rankine cycle. The fundamentals for direct steam generation in parabolic troughs have been developed in recent years, the feasibility was successfully demonstrated at a solar powered test facility reaching steam temperatures of 400°C at a maximum pressure of 100 bar. Important components for the accelerated ...
