Thermocline tank for thermal energy storage

Abstract

A thermocline tank (30) is proposed for thermal energy storage, comprising: - a chamber (20) forming a storage volume for a liquid, the chamber (20) having an inlet (21) configured to receive a liquid flow rate, referred to as the inlet flow rate (Q1), - a diffuser (1) disposed within the chamber (20), the diffuser (1) being configured to direct the inlet flow rate (Q1) of the liquid into the chamber (20), comprising: - a body (2) extending along an axis (D2), the body (2) having a side wall (3), a bottom wall (4) and an outlet (5), - a circulation channel (6) in fluidic connection with the inlet (21) of the chamber (20), the circulation channel (6) extending inside the body (2) between a first end (7) disposed on the side wall (3) and a second end (8) disposed opposite the wall background (4).
