Resumen:
In Argentina there exist children?s dining rooms where infants and their mothers take lunch atnoon and glasses of milk in the afternoon. These dining rooms are established in rural ormarginal urban areas. Solar ovens are an interesting option for cooking with less expense ofmoney, and they diminish environmental impact in these zones. A solar oven with downwardand upward solar gain was built and tested. Upward solar gain is through Fresnel reflectors. Theuse of Fresnel reflectors resulted in higher heating power as compared to a solar oven withupper reflectors only. The performance with different numbers of Fresnel units was comparedwith a single-reflector solar oven with no lower Fresnel reflectors. Oven power was analysedand the result indicates that power grows as the number of Fresnel reflectors increases: it growsby 55% using 3 to 9 Fresnel reflectors, and by 34.6% with 3 to 6 Fresnel reflectors. Thesevalues are enough to cook several rations of food, and make this oven appropriate for use indining rooms in developing countries.
