MODELLING OF A STAND ALONE SOLAR COLLECTOR

The work described in this paper concerns the modelling of a standalone air solar collector producing low temperature heat. The main role of the system is to avoid unfreezing temperatures and to reduce humidity in a room or in an unoccupied home during a long time, with only solar radiation. In view to dispose an essential sizing tool for this solar collector, we developed a mathematical model based on energy balance equations and on the characteristics of each prototype. This model allowing to simulate the thermal behaviour of the solar collector, was validated using experimental data collected by telemetry in six operating sites.
