comparison of candidate materials for seasonal storage of solar heat
... in the simulation model the heat transport is due to some temperature difference and does not contradict the law of thermodynamics. The seasonal heat store in Figure 4 is modelled as a so-called "configurable subsystem". This means that it contains several heat store models ("members"), from which o ...
