Design, development and testing of a double reflector hot box solar cooker with a transparent insulation material

摘要

A double reflector hot box solar cooker with a Transparent Insulation Material (TIM) has been designed, fabricated, tested and the performance compared with a single reflector hot box solar cooker without TIM. A 40 mm thick honeycomb made of polycarbonate capillaries was encapsulated between two glazing sheets of the cooker to minimise convective losses from the window so that even during a n extremely cold but sunny day two meals can be prepared, which is not possible in a hot box solar cooker without TIM.
