Concentrator for solar air heater
Applied Physics, 1979A focusing collector for air heater, the concentrator being Fresnel lenses, is here examined. The sunlight is focalized on black-body metallic sheets, contained in an insulated box, through which the energy is transferred to the fluid (dry air). The sheets, having the same height, are arranged at a distance one from another increasing from the center ...

Efficiency of solar air heaters
Applied Solar Energy, 2016This paper proposes a method for finding the efficiency of solar air heaters based on a comparison of their thermal and hydrodynamic characteristics with the thermal and hydrodynamic characteristics of flat plate-type solar air heaters. Calculations performed for different designs of air heaters have shown the great potential of this method to create ...

Matrix solar air heaters – A review
Renewable and Sustainable Energy Reviews, 2016Abstract Improvement of thermal performance of a solar air heater can be obtained by enhancing the rate of heat transfer. Thermal efficiency of matrix solar air heater is higher in comparison to conventional type. Number of studies has been reported in the literature on the performance of matrix air heater with different material packing and ...

Abstract The performance of a solar heater depends on the losses from the collector surfaces. The losses through the bottom and sides of the heater may be reduced or almost eliminated by the use of adequate insulation. In an attempt to reduce the losses from the glass cover of the simple two-glass cover air heater, a unit was constructed in which ...

Solar air heaters with external recycle
Applied Thermal Engineering, 2009The effect of external recycle on the collector efficiency in solar air heaters has been investigated theoretically. The application of external-recycle operation to solar air heaters actually has two conflict effects. One is the desirable effect of increasing fluid velocity to decrease the heat transfer resistance.
