This is a dissertation report on optimizing heat insulation ofa solar oven. Solar oven is a box that uses heat radiatingfrom the sun to cook or heat the food. Solar oven not widely used because of the poor performance compared with conventional ovens. Solar oven performance is inconsistent; depend on the time of day, weather and geographic location. Temperature rise in solar oven is slow compared with conventional oven. Heat loss through the insulator is one of the disadvantages of a solar oven. The objective of this project is to investigate the suitabilityof insulation materials and thicknesses to use in a solar oven. This project will analyze different types of materials which are suitable as insulation from varies point of views and criteria. The existing solar oven model will be studied and the relevant journal will be as a base for my study. Testing and experiments will be made to evaluate the capability of the material in the system, The final result show that glass wool is the best insulation material compared with crumpled paper and cotton insulation. Glass wool is chosen base on the cost of material, availability in market and thermal conductivity. All relevant data, calculation, and discussion will be provided at the end of this report.
