MIRROR BOOSTERS FOR SOLAR COOKERS--I

Abstract

An analysis of the effects of providing a single adjustable mirror booster, hinged on a box type solar cooker, is made. The mirror is hinged on one side and points toward the south. The total energy falling on the cooker aperture is calculated for a latitude of 18°N (Warangal City) and for five different declinations of the sun (five different days in a year). The effects of mirror adjustment are analysed under three categories to determine the energy boost. The calculations clearly demonstrate the choice among intermittent adjustment, continuous adjustment and fixed orientation of the mirror. Only beam radiation is considered in the calculations.
