Description
  • Příspěvek se zabývá simulací a měřením zemního výměníku tepla. Nově vyvinutý tepelně-vlhkostní model zemního výměníku tepla (ZVT) již byl validovaný s pomocí analytického řešení, srovnání s měřením doposud chybělo. Teoretické předpovědi vyvinutého vlastního modelu ZVT jsou porovnávány s měřením in-situ na dvou ZVT. Porovnání mezi měřením a simulací ZVT sice neukázalo absolutní shodu, avšak matematický model a později i dlouhodobé sledování reálných ZVT poskytují jasnou informaci o procesech probíhajících během provozování ZVT a odkrývají tak potenciál využití ZVT ve spojení s větráním budov.

  • The paper deals with the earth-to-air heat exchanger (EAHX) simulation and monitoring. A newly developed hygro-thermal model for transient simulation of earth-to-air heat exchangers has already been validated against an analytical solution; a comparison with performance data of real EAHXs has missed so far. The model is tested against long-term monitoring of two simple earth-to-air heat exchangers connected with mechanical ventilation in two low-energy family houses. In parallel, the differential sensitivity analysis is used for a model assessment. The comparison between measured data and numerical simulation does not correlate absolutely. However, the simulation is capable to show limitations and energy saving potential of the exchanger with respect to building ventilation. The model brings clear information about processes which take place during earth-to-air heat exchanger operation.
