| Abstract: | The paper has come up with the Calculated shape factor of upward heat conduct in embedded pipe heated floor through mirroring and simplifying structures above the layer of insulation. It has also formulated the equivalent heat resistance of floor based on shape factor and developed a new simple algorithm for heat gain from floor using equivalent heat resistance. It shows the new algorithm is accurate, after being compared the results of new algorithm with that of numerical simulation basied on differential equation of heat conduct. |
