Amélioration de l'efficacité énergétique d'une solution innovante de chauffage basse température et de rafraîchissement

Abstract : In the current context of improvement of the housing energy efficiency, new heating devices have to be foreseen. We have developed an innovative heating and cooling generator. This device is based on the use of thermoelectric modules working as a heat pump via a power supply. This thesis aims to improve the energy efficiency of the whole system including a low temperature heat floor (global coefficient of performance). This work is based on different analytical and numerical models validated experimentally. These models help to design an optimized device configuration and to develop an optimal management strategy in order to meet the variable power and temperature demands. Multifunctional heat sinks for the generator are designed and studied experimentally in order to maximize the system performances. By coupling the system to housing, a significant improvement of the device performances is shown compared to thermoelectric heat pumps with a classical configuration.
