STUDY AND MODELING OF THE OPERATION OF A SOLAR WATER HEATER IN TOGO

The work presented concerns the analysis of the behavior of a flat water solar collector. Mathematical modeling, based on the global energy balance method, takes into account the initial conditions associated with the sensor. This modeling uses an estimate of the evolution of global solar flux. The model's resolution was made under a Matlab environment. The results of the numerical simulation make it possible to compare the temperature of the water at the output of the sensor as well as the power measured at the simulated values. The results obtained show that the model is valid and can predict the performance of the solar water heater. These results also show that the regression coefficient R? is about 0.9 which is very interesting. This model can therefore be used to describe the performance of a solar collector in Togo.
