The environmental challenges stemming from fossil fuel consumption have spurred many countries and stakeholders to pursue energy transition solutions. One such technology is the direct solar floor system, which enhances sustainability and reduces environmental impact. In this study, a three-dimensional numerical model of a floor heating system was developed using the Comsol Multiphysics software. The model’s numerical results were found to be in satisfactory agreement with experimental data regarding air temperature. Furthermore, a parametric analysis was conducted to evaluate the impact of different configurations of piping and screed layer thicknesses on floor surface temperature and heat flux. The findings reveal that a spiral configuration combined with a 75-mm-thick concrete screed layer achieves an optimal floor surface temperature of approximately 33.09 °C and a heat flux of around 556.36 W. These specific parameters ensure a high level of thermal comfort, particularly suitable for bathroom environments.

摘要

The environmental challenges stemming from fossil fuel consumption have spurred many countries and stakeholders to pursue energy transition solutions. One such technology is the direct solar floor system, which enhances sustainability and reduces environmental impact. In this study, a three-dimensional numerical model of a floor heating system was developed using the Comsol Multiphysics software. The model’s numerical results were found to be in satisfactory agreement with experimental data regarding air temperature. Furthermore, a parametric analysis was conducted to evaluate the impact of different configurations of piping and screed layer thicknesses on floor surface temperature and heat flux. The findings reveal that a spiral configuration combined with a 75-mm-thick concrete screed layer achieves an optimal floor surface temperature of approximately 33.09 °C and a heat flux of around 556.36 W. These specific parameters ensure a high level of thermal comfort, particularly suitable for bathroom environments.
