Résumé en anglais

Thermal energy storage (TES) is a key issue in efficient energy system applications, especially in the context of renewable energies. In this respect, phase change materials (PCM) have attracted interest as an active solution for efficient energy management, particularly in the building sector. This paper presents a modeling of a thermal battery based on PCM in the case of solar systems assisted by heat pump (SAHP). The storage tank allows to store the heat produced via unglazed solar panels (Batisol®) and represents the heat source of the heat pump. The heat pump can supply the heating and domestic hot water (DHW) needs of a building. The storage consists of a block of PCM contained between two plates of heat transfer fluid (HTF). A 2D model is used to describe the behaviour of the PCM and a 1D model is preferred for the HTF plates. The objective of the study is to dynamically simulate the thermal behaviour of this storage for different hot inlet temperature profiles: step, trapezoidal functions and profile of the temperature at the outlet of the thermal panels for a winter and summer period of 8 days. This 2D model would be useful to validate a simpler model for optimisation of the operational parameters of the system.< Réduire
