Realistic experimental heat transfer characteristics of radiant floor heating using sidewalls as heat sinks

摘要: Abstract Apart from most of the relevant literature, case studies are conducted by generating a number configurations using sidewalls as heat sinks to simulate winter conditions. These correspond distinct loss rates and means living environment, heated an underfloor heating system. In this study, transfer characteristics system in test chamber have been experimentally determined, while chilled water flows through circuits arranged at four different configurations. Simultaneously, supply temperatures ranging 30 °C 45 °C, flow rate 0.09 kg/s applied. As result, when temperature is 35 with increasing cooled sidewalls, configuration 2, 3, 4 sources, total fluxes floor found 66.36 W/m2, 81.79 W/m2, 85.19 W/m2, respectively. Correlations for convective coefficient flux derived average error of ± 11% and ± 4.5% obtained, 87.5% 94% measured data remain in ± 30% and ± 10% bands considering empirical correlations, Measured calculated given other researchers validate their models.
