Abstract
Preservation of food is major concern in India. In rural areas where electricity is not reached, clay pot is best option for preservation. The steady-state performance of clay pot is already carried out by considering cylindrical shape in the literature. But, in actual practice shape of the clay pot is curved; hence, it is necessary to study the curvature effect on the performance of clay pot refrigerator. For particular cooling load, the refrigeration temperature and geometrical dimensions can be predicted under various ambient conditions. Introduction of curvature in model reduces size of pot for the same refrigeration temperature. For a parabolic geometry, approximately 7–18% higher efficiency can be achieved as compared to cylindrical shape at same surface area for given atmospheric relative humidity and temperature. Also, overall size of model can be reduced. Hence, more compact model can be used for same heat transfer.
