Zusammenfassung: | The design of heat exchanger fields is a key phase to ensure the long-term
sustainability of such renewable energy systems. This task has to be
accomplished by modelling the relevant processes in the complex system made up
of different exchangers, where the heat transfer must be considered within
exchangers and outside exchangers. We propose a mathematical model for the
study of the heat conduction into the soil as consequence of the presence of
exchangers. Such a problem is formulated and solved with an analytical
approach. On the basis of such analytical solution, we propose an optimisation
procedure to compute the best position of the exchangers by minimising the
adverse effects of neighbouring devices. Some numerical experiments are used to
show the effectiveness of the proposed method also by taking into account a
reference approximation procedure of the problem based on a finite difference
method. |
