| Popis: | A knowledge-based model aiming to check the correct sizing of an active indirect solar water heating system with an external heat exchanger is presented. This model has been subjected to an experimental validation trial where the effect of input data measurement uncertainties on each simulated variable was exposed. It was noted that each input data measurement error has a different effect depending on the time and the simulated variable. After the experimental validation, in order to take into account the fouling effect when controlling a solar installation sizing, its impact on solar installation energetic performance was studied. The results show that it can cause the decrease of the solar installation energy intake and of the storage tank outlet temperature to load, respectively by a value of 9.06% and 1.68 °C. It can also cause the increase of the collector outlet temperature by a value of 1.3 °C. Finally, the presented tool was used to control solar installation sizing. The sanitary, energetic and longevity aspects were examined. These latters were respectively checked by evaluating the storage tank outlet temperature to load, the energy produced by the solar installation and the collector outlet temperature. |
