Storage models have been developed for four of the storage concepts that have been studied within Subtask B of IEA-SHC Task 32. These are available from the authors. They are: 1. Thermo-chemical accumulator model for the commercial product ClimateWell 10; 2. detailed model for open adsorption in a zeolite honeycomb structure; 3. simple theoretical model for generic chemical reactions; and 4. closed adsorption store model. Two of the models have been developed in TRNSYS directly, whereas one has been developed in Matlab and the fourth as a PEDX routine. The latter two models can be linked to TRNSYS and can thus be used in system simulations with the Task 32 boundary conditions. The models vary significantly in detail and require varying degrees of measurements for identifying parameters. For each model, the basic function of the store is described in addition to the model itself. The main assumptions and limitations of each model are stated. Finally details are supplied about the validation of the model.
