| description | Air heating is currently an essential part in many industrial and residential applications. One of its disadvantages is the higher energy consumption. Therefore, the renewable energy sources present now different solutions in order to decrease the energy consumption and to enhance the performance of existing systems by the hybridization. For these reasons the energy management at all levels became one of the most important research. In this context, the present paper proposes a design for a solar air heater that could be applied in more than one application. A modelling and an experimental study are presented. The presented solar air heating system allows reducing the energy consumption by replacing completely or partially an electrical air heating system. In addition, an in-house code is developed in order to simulate the suggested solar air heater and to study its performance. The experimental setup is implemented and designed to validate the developed code. Accordingly, a relative error of the modelling is estimated and it varies between 4 and 14%. Finally, the system is evaluated economically and environmentally by assessing the effect of replacing the electrical heating system of a fruit dryer by the suggested solar heating. It has been shown that adopting such system allows to save up to $106 per year and to reduce about 2045 kg of carbon dioxide emission. |
