Simulation of a seasonal, solar-driven sorption storage heating system

摘要

A detailed simulation setup for a closed solid sorption storage system is developed and validated using extensive experimental data of a demonstration test rig built up in the EU-funded project COMTES. The modular implementation of the sorption process allows to discuss enhanced operation modes like the ‘charge boost’ in the simulation. The validated model is used to optimize the storage system and to predict its performance for several reference scenarios. As an example, a storage system with 6 m~3 of storage material achieves fractional thermal energy savings in the range of 70-75% for a standard single family house in middle Europe.
