Conception d’une pompe à chaleur haute température pour des applications de stockage d’énergie thermique.

Design of a high-temperature heat pump for thermal energy storage applications.

Résumé

The improvement of the heat storage technologies will allow the security of supply and dispatchability of renewable energy sources (RES), enabling their better integration in the electricity grid. This work proposes a solution by means of a Compressed Heat Energy STorage (CHEST) technology. In CHEST concept a high-temperature heat pump (HTHP) uses surplus energy from RES to pump heat from low-temperature source to a high-temperature thermal energy storage (HT-TES) system. Later, stored heat is discharged to drive an organic Rankine cycle (ORC) producing electrical power. In this paper detailed design and sizing of a HTHP for a laboratory-scale CHEST prototype, in the range of 10 kWe, is presented. Parametric studies were done to assess the HTHP’s performance under different operating condition. The results showed that the proposed HTHP can reach a coefficient of performance (COP) of 4.86, at source and sink temperatures of 85 and 133 °C, respectively.
