MEALLA SANCHEZ, Luis Enrique  e  BONAVERI ARANGOA, Pablo Daniel. Construction alternatives using low-cost materials for the thermal test of box-type solar cookers. Rev. ion [online]. 2012, vol.25, n.1, pp.17-23. ISSN 0120-100X.

This document presents the evaluation of a different set of solar ovens in terms of their thermal performance by the RICSA protocol. For this purpose, four solar ovens were constructed differentiated mainly by the type of isolation and plates. All were exposed to direct solar radiation. First, only the collector plate was heated to measure thermal losses and efficiency and second, a determined amount of water was introduced to measure the thermal power of the solar oven. Additional parameters like the time in which it reaches the temperature of effective boiling point and the time in which it maintains functioning without intervention of the operator also were measured. The analysis provide empirical evidence regarding adequate levels of thermal performance of solar ovens constructed using iron on one hand, and aluminum on the other. It is recommended to extend the use of this type of equipments given the priceeffi ciency obtained in the experiments.
