Two-dimensional model of direct solar slab-on-grade heating floor
- Centre de Developpement des Energies Renouvelables, Bouzareah (Algeria)
The altering direction implicit (ADI) method is used to solve the two-dimensional heat equation applied to the system described in this paper. The coupling equations between flat-plate collectors, heating floor and ground had been developed. The model also takes into account the solar flux falling on the floor through the south oriented glazed wall. The theoretical results were compared to the experimental data performed in Bassens (southwest of France) during the period of September 1981 to May 1982. It was shown that the model outputs were in good agreement with the measured data. However, some doubts are considered concerning lower boundary conditions. Also is given a simple technique to evaluate the most appropriate initial conditions to drive the computational program developed here. Finally a study of some main parameters was carried out.
