Comparison of thermal performances of flat plate and evacuated tube solar air collector at different flow rates: experimental analysis
The thermal performances of an evacuated tube solar air collector and flat plate solar air collector are experimentally investigated at different flow rates of air. The evacuated tube solar air collector has 40 evacuated tubes and surface area, 4.44 m². This setup consists of a header of square shape. The header has a circular pipe at the centre through which the air flows. The setup contains ...

Development and performance evaluation of 0.16 m 2 solar point thermal energy collector compared with flat plate collector
Renewable energy systems such as wind, solar and biomass are significantly more land intensive than traditional fossil fuels. Renewable energy increases diversity of energy supplies and can replace diminishing fossil fuel resources over the long run; their use in place of fossil fuels can substantially reduce greenhouse gases and other pollutants. Application of solar energy for domestic and ...

Solar-powered Stirling engines: a low-cost possibility for village power, pumping and cooling
Stirling engines are heat engines that operate on a closed thermodynamic regenerative cycle and are used as power systems, refrigerators or heat pumps. Recent developments in Stirling technology allow the use of low temperature heat sources including flat plate solar collectors. New concepts for low-cost, low ΔT Stirling engines that may be made by village craftsmen using locally available ...

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 ...

Thermal management of non–concentrating photovoltaic panels under extreme ambient conditions
Solar photovoltaic modules have reduced efficiency levels when the ambient temperature is very high. In this paper, the temperature and the efficiency of a non–concentrating flat plate collector is determined by a one dimensional steady state analysis at different solar radiation levels for the city of Riyadh, Saudi Arabia where the radiation intensity and ambient temperatures are very high. 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 ...
