Originální abstrakt

The paper deals with a comparison of the 1D and 3D model of a thermally activated wall panel with a phase change material. The 3D model was created in the off-the-shelf simulation tool COMSOL and the 1D model was an in-house developed TRNSYS type. The main advantage of the 1D model is the short computation time. It, however, comes at the expense of lower accuracy and less detailed results. In most building performance simulations, the detailed knowledge of the temperature distribution over the surface of a wall is not important. For this reason, the results of both models were compared in terms of the average surface temperature of the wall panels, the outlet water temperature and the overall heating and cooling capacity of the panels. The two models provided very similar results for the mass flow rates of water from about 0.001 kg/s but the discrepancies increased with the decreasing mass flow rate.
