Abstract

The subject of the research is a so-called the solar pot which is a new invention protected at the Hungarian Intellectual Property Office (utility model, patent number 5489). The pot can be used for heating or cooking (foods, drinks or other fluids). It has a similar structure to a double pipe heat exchanger with an outer jacket and an inner cooking space. Although it has been manufactured, its capabilities have not been tested neither by modelling and simulation nor with experiments and measurements, so these investigations represent a completely new research field. The goal of this work is the mathematical modelling of the pot which allows the prediction of the pot temperature. The modelling and the first simulation results based on it are presented in this paper, based on which conclusions can be drawn regarding the efficiency and applicability of the pot. Future research plan is also presented which includes the construction of an experimental system of the pot and a solar collector, and further modelling of the system and system elements. On the system, measurements will be made under different conditions, allowing the assessment of the pot’s functionality and the validation of the mathematical models.
