Modeling Buried Hot Water Thermal Energy Stores
Abstract
Thermal losses of buried medium and large-scale TES depend on the construction type and the boundary conditions. It is found that available coarse-structure TES models simplify the real processes such that a detailed analysis with the objective to enhance TES design is not possible. Accurate TES modelling for transient energy simulations requires detailed description of heat and moisture transfer processes in the envelope and in the surrounding soil. In this paper, exemplarily, essential features of the new hygrothermal model are demonstrated.
