Abstract
The report presents two simple models of a stratified hot water storage tank. Both are one-dimensional models of the thermal stratification in the tank water. Temperature variations in horizontal direction is neglected, i.e. only the vertical water temperature distribution is calculated. Comparison is made to a 152 l experimental storage tank. The first model has heat loss terms added, which describe the heat losses to the air around the tank. Some parameters in the model are adjusted by a parameter estimation procedure through a state-space formulation of the model. This is done by means of Kalman-filtering the model and experimental data. The second model is found in literature and is analytical. It has no heat losses, but takes some of the tank`s wall heat capacity into account. Empirical parameters for this model have to be given better values in further work. 14 refs., 12 figs.
