- Abstract
A simplified mathematical model was established to calculate the heating transfer capacity through MATLAB program. Compared with the results of thermal performance test, the mathematical model was reasonable with a maximum error less than 5.15%. According to the results of model and experiment, in the constant flow condition, heating capacity of the ceiling increases as the temperature increases, meanwhile heating capacity decreases as the heat exchange coil spacing increases.
