Operation optimization of prefabricated light modular radiant heating system: Thermal resistance analysis and numerical study

The utilization of prefabricated light modular radiant heating system has demonstrated significant increases in heat transfer efficiency and energy conservation capabilities. Within prefabricated building construction, this new heating method presents an opportunity for the development of comprehensive facilities. The parameters for evaluating the effectiveness of such a system are the upper surface layer’s heat flux and temperature. In this paper, thermal resistance analysis calculation based on a simplified model for this unique radiant heating system analysis is presented with the heat transfer mechanism’s evaluation. The results obtained from thermal resistance analysis calculation and numerical simulation indicate that the thermal resistance analysis method is highly accurate with temperature discrepancies ranging from 0.44 °C to −0.44 °C and a heat flux discrepancy of less than 7.54%, which can meet the requirements of practical engineering applications, suggesting a foundation for the prefabricated radiant heating system
