TI  - AN EXPERIMENTAL INVESTIGATION ON RADIANT FLOOR HEATING SYSTEMS AT VARIOUS OPERATING CONDITIONS
AB  - In this study, heat transfer characteristics pertaining to a heated radiant floor are investigatedexperimentally. In order to achieve this aim, experiments have been conducted within extended supply watertemperature ranging from 30 oC to 55 oC, and mass flow rate ranging from 0.056 kg/s to 0.125 kg/s according toexperimental condition ranges in the relevant literature. Correlation comparison has been accomplished using alarge number of experimental data including pioneer studies and international standards regarding with thedetermination of heat flux and heat transfer coefficients. Moreover, novel correlations providing convective,radiative and total heat fluxes have been derived, and it has been observed that most of the outcomes of correlationsremain within deviation bands of ±15%, ±5% and ±20%, respectively. Apart from the literature, heat fluxcorrelations corresponding to each heat transfer mechanisms are given and evaluated separately. Throughoutexperimental studies, the proportion of the radiative heat transfer to total one is found 60% approximately.Measured experimental data are given in the paper for other researchers validation problems on their theoreticaland numerical works.
