- Abstract
It is worthwhile for saving energy and protecting environment to use conductive concrete as an indoor heating engineering material. Indoor temperature is the key concern of heating system. Based on convection, radiation and Joule effect, a method to calculate temperature of concrete and indoor air was presented. The method did not need to model the air, which simplified the preprocessing. The numerical result agreed with experiment satisfactorily, with a difference of 2.40%, which proved the correctness of the model. Numerical tests of different conditions showed that electrical resistivity with higher potential than power voltage and concrete thickness was the key to increase heating efficiency.
