Abstract : A large number of solar cookers have been developed in many countries. These cookers are broadly divided into a direct or focusing type, indirect or box-type and advanced solar cookers. The focusing and box-type solar cookers are for outdoor applications. The advanced solar cookers have the advantage of being usable indoors and thus solve one of the problems, which impede the social acceptance of solar cookers. The advanced type solar cookers are employ additional solar units that increase the cost and the cooking process can not be done in the evening or on cloudy days. Therefore, the solar cooker must contain a heat storage medium to store thermal energy for use during off-sunshine hours. Hence, one of the main objectives of this project is to study the thermal performance of a box-type solar cooker with different PCMs. The selected commercial grade PCMs include erythritol (Tm = 118 oC), acetanilide (Tm = 118 oC) and Magnesium chloride hexahydrate MgCl2.6H2O (Tm = 116.7 oC). Another aim of this study is to investigate the influence of melting/solidification cycling of the PCM on its thermo-physical properties; such as, melting point, latent heat of fusion, thermal conductivity, density, etc. These properties can be measured using the differential scanning calorimetric (DSC) and differential thermal analysis (DTA) techniques. Furthermore, the compatibility of the PCMs with Al and stainless steel will be investigated.
