A Thermochemical Heat Storage System for Households: by Armand Fopah Lele

By Armand Fopah Lele

The booklet deals a accomplished file at the layout and optimization of a thermochemical warmth garage method to be used in structures. It combines theoretical and experimental paintings, with a unique emphasis on model-based tools. It describes the numerical modeling of the warmth exchanger, which permits restoration of approximately thirds of the waste warmth from either sunlight and thermal strength. The ebook additionally offers readers with a image of present examine on thermochemical garage platforms, and an in-depth evaluate of crucial innovations and techniques in thermal administration modeling. It represents a priceless source for college kids, engineers and researchers drawn to thermal power garage techniques, in addition to for these facing modeling and 3D simulations within the box of power and strategy engineering.

Sample text

Let comeback on the criterion energy storage density which brings controversy in some storage material discussion. It is most valuable characteristic of a thermal energy storage system. In the following different used terms of energy density are clarified: 1. the theoretical energy density (kJÁkg−1), widely used for sorption systems, is the maximal energy density of the material considering the porosity; 2. The mass energy density (kJÁkg−1), which is the ratio between the reaction enthalpy and the molecular mass; 3.

5 Necessary multidisciplinary field to the development of a TESS based on chemical reactions (adapted from Pardo et al. 2014) with some cogenerations. Then, different storage systems are reviewed and the reason of selecting thermochemical system is highlighted. Finally, some examples of systems are shown and thermodynamic study performed, followed by brief overview of heat and mass transfer with sorption and chemical reaction. The third chapter shows first, a short comparative study between different reactors for such thermochemical storage system.

Picture adapted from (Webber 2013) charging and discharging phases, hence the name thermal battery. The aim is to understand those phases in which chemical reaction with heat and mass transfer are coupled, so that prediction and optimisation can be made. As thermochemical storage systems are still at a very early stage of development, most of the studies are limited to laboratory scale. Considerable amount of time, money and efforts are required before a commercially viable system becomes operational.
