SorpLib: Dynamic simulation of adsorption energy systems
The design of adsorption systems is challenging due to their intrinsic dynamic nature: During operation, adsorption devices switch between ad- and desorption phases, meaning they work discontinuously. In addition, they have a characteristic energy output peak at the beginning. Besides, adsorption devices consist of several components, all influencing performance. Therefore, in an optimal design, these components must be balanced, avoiding oversized components on the one hand and bottlenecks on the other. To meet this optimal design challenge, the Modelica LTT Adsorption Library has been developed.
The LTT Adsorption Library is a Modelica library, which allows the building of all kinds of adsorption energy systems, e.g., adsorption chillers and heat pumps, thermal adsorption storage systems, or desiccant systems. The library includes basic models for the different components of adsorption systems. This modular approach allows the user to develop new models quickly. Additionally, the library contains exchangeable media models and a database with many different adsorbent/adsorbate working pairs.
An overview of the library, including several validated examples, can be found here.Copyright: © Institute of Technical Thermodynamics, RWTH Aachen University
