ABSTRACT: Solar cookers are a good option in developing countries with high solar
potential for environmentally friendly cooking and reduced pressure on forests.
However, they are still affected by the intermittency of the sun. In order to
overcome this problem, in this work, a box type solar cooker integrated Jatropha
oil as a heat storage material is fabricated and experimented with. The design
was examined with a maximum stagnation temperature of 157.7°C. The recorded
cooking power vanished between 78.4 and 103.6 W, while thermal efficiency
varied from 41.26% to 58.78%. The energy transfer cycle test, including charge
and discharge revealed that 91.18% of the heat lost through the cooker could be
recovered by the heat storage unit and a large amount is restored to the system
during cloudiness or a temperature perturbation.
