IMPLEMENTATION OF TWO-DIMENSIONAL FOUNDATION MODEL FOR RADIANT FLOORS INTO ENERGYPLUS
Pyeongchan Ihm, Moncef Krarti
In this paper, a two-dimensional transient numerical model for ground coupled heat transfer for radiant floors is developed and integrated into EnergyPlus. The model is first validated against experimental data. As an application of the integration of the model within EnergyPlus, thermal performance of a typical radiant system in a typical residential house is evaluated using both the new two-dimensional model and the existing radiant panel model currently used in EnergyPlus. Moreover, guidelines are presented to illustrate how the model can be used to calibrate the existing model within EnergyPlus.
