摘要：
This paper analyzes use of geodesic domes as low cost and practical solar energy drying systems, especially for developing countries. A geodesic dome solar fruit dryer was designed, constructed and tested for drying grapes. The structure was constructed using wooden members, covered with transparent tedlar plastic and a black absorber inner shell. Fresh air is heated in the space between the outer shell and the absorber sheet. The hot air then passes through the fruits on the trays and exits from the top. The dryer was tested for drying grapes under two different modes, namely natural convection and forced air flow. In addition, theoretical results were obtained by thermal-electrical simulation and considering the heat and mass transfer phenomena between the air and the grapes.
