Abstract：
A two-dimensional steady-state heat transfer model of floor construction for the radiant floor heating system was estasblished. The influence of water average temperature, indoor temperature, pipe distance, pipe burying depth, hot water flow rate, diameter of the pipe on the heat flux and temperature distribution was analyzed. The results show; the heat flux density, which increase with the pipe diameter and the water average temperature, and decrease with the indoor temperature, pipe distance, pipe burying depth, the temperature difference, which increase with the pipe diameter, the water average temperature, pipe distance, and decrease with the indoor temperature, pipe burying depth; however, which were less affected by the hot water flow rate.
