Experimental and numerical analysis of lightweight radiant floor heating system

The operating characteristics of lightweight radiant floor heating (LRFH) system were analyzed by experiments and numerical calculation. A heat transfer model for the evaluation of LRFH system was investigated and a corresponding calculation program was developed. The effects of design parameters on performance of LRFH system were studied by means of calculation program previously validated through an experimental campaign performed in a laboratory. Meanwhile, the heat-transfer capability, temperature field distribution and thermal comfort of LRFH system were analyzed by experiments. The results indicate that LRFH system shows fine thermal stability and thermal comfort.
