Resumen:

This paper presents a system of indirect air heating coupled to a drying chamber (type tunnel) for agricultural product. The energy for the drying process comes from a solar water heating system (92.4 m2) with thermal storage or working directly. The water heating system has thermal efficiencies between 47-57%, depending on the temperatures reached by the water in the hot water thermal storage tank and the weather conditions. The indirect air heating system is by means of a heat exchanger of finned tubes that has an average heat transfer capacity of 50 kW, delivering temperatures at the entrance of the tunnel between 45-75 °C. The heat transfer efficiency of the water-air exchanger is around 85%. © 2019. The Authors.
