Abstract [en]

Hydronic floor heating models provide predictions in estimating heat transfer rates and floor surface temperature. Information on the model performance, range of validity of its results are often lacking in literature. Researchers have to know the accuracy and robustness of the model outcomes for performing energy and climate comfort calculations. This paper proposes a novel validation methodology based on the uncertainty analysis of input data/parameters of 1D hydronic floor heating model tested in a thermostatic booth simulator and compared with experimental measurements. The main results are: i) predictions accuracy between 0.4-2.9 % for Tf and between 0.7-7.8 % for qup when the serpentine has tube spacing of 0,30 m, ii) predictions accuracy between 0.5-1.4 % for Tf and between 8.7-12.9 % for qup with p = 0:15 m iii) Tfld mostly affects predictions with oscillations between 6.2-2.2 % for qup. This model provides robust and reliable predictions exclusively for qup when p = 0:30 m.
