RESUMO

In view of the importance of food supply, it seems rational that all potencial energy sources should be utilized. This worldwide concern led to a wide analysis and application of solar energy for cooling and freezing of foods. The Faculdade de Engenharia de Alimentos e Agrícola- - Unicamp designed and built a solar absorption refrigeration system with the unique feature of direct heating of the solution and air-cooling. The present study concerns a working out of data on intensity of solar radiation inciding on the flat-plate collector and studies of the behavior of the system under local conditions. A steady state simulation was carried out and the results pointed out alternatives that should be confirmed experimentally for future performance im-provement
