摘要: Abstract Heat output and uniformity of surface temperature distribution are primarily concerned by designers users radiant floor heating. The testing approach, conditions calculation the heat at each stage program different among test standards. In this paper, a mathematical model to calculate heating system was proposed. Measured data from experiments used validate proposed model. Based on simulation model, four current standards in China, Europe, America Japan were simulated. results show that same sample is under Meanwhile, simulations carried out various non-heating temperatures. indicate has significant impact floor. differences capacity vary 2% 7%. Hence, parameter, difference between average water area weighted surfaces, introduced revise characteristic equation based Chinese standard.
