Summary

The storage and utilization of sensible and latent heat in materials over extended periods, such as entire seasons, are often hindered by heat losses. Adsorption Thermal Energy Storage (TES) offers a promising solution for the long-term storage of excess and solar thermal energy. This research focuses on the integration of an adsorption chiller (ADC) into four distinct configurations, referred to as cascade ADC-ADC. Each of these configurations employs the same working pair: Silica gel (RD type) and water. The primary objective is to evaluate and compare the energy storage density (ESD) of this cascade ADC-ADC system in contrast to ADC conventional energy storage methods, aiming to identify the most promising approach to cascade energy storage. To achieve this, we present a novel numerical model developed using MATLAB, rigorously validated against a combination of experimental and numerical data from existing studies. Our investigation reveals a significant enhancement in ESD when considering the various configurations within the cascade system. Among these, it is noteworthy that in type A, the system exhibits the highest ESD when compared to conventional and other cascade energy storage types. In addition to ESD assessment, this study also calculates the overall efficiency of the thermal storage system. The findings of this research hold substantial implications for the field of thermal energy storage and further the development of sustainable and efficient solutions for long-term energy storage.
