Prise en compte du champ thermo-convectif pour le contrôle thermique des espaces habitables

Abstract : Real-time control of air-conditioned indoor spaces needs models of temperature distribution and air velocity field in rooms. Models, based on CFD, give this information but they are improper for real-time applications. Therefore, a reduced model is needed. The purpose of this study is to reduce the size of a CFD model by first considering the velocity field fixed and solving only the energy balance equation, then putting this equation in the form of state-space and finally by reducing its order by Proper Orthogonal Decomposition (POD). This algorithm was applied to a room equipped with a fan coil. The state space form of the reduced order model allows to estimate the temperature in the occupancy zone, without a direct measurement, and to feedback it to a controller. Several controllers are compared, they are all designed with the internal model theory.
