Comparison Study on Indoor Temperature Distributions with Radiant Heating and Convection Heating

The capillary radiant panel for heating studied in the research can run with 30-50°C low-temperature heating resources. It is using of prefabricated forms, achieves heating and decorative integration, and overcomes construction inconvenience of low-temperature hot water radiant heating system. According to the heat transfer mechanism of heating terminals, the established numerical models were compared with laboratory testing to verify the accuracy of these models. Then the CFD software was applied to study the thermal environment of the room, which heated by the ceiling heating panel and heating convector separately. The distribution of air temperature field, as well as the thermal properties of these heating terminals was gained. Capillary radiant panel for heating, as a new heating method, has great potential for application development. The numerical study of this paper will be helpful makes such products extend in China.
