Temperature distribution in a panel-radiant heating system

In this study, a computer model was developed in Comsol Multiphysics to determine and evaluate the temperature distribution in a panel-radiant heating system with a heated floor. A panel-radiant heating system consisting of a concrete layer with dimensions of 4 × 3.3 × 0.1 m³ was selected, and copper pipes with an inner diameter of 2 cm and total lengths of 64.84 m and 64.24 m were installed within this volume. Water was used as the heat carrier. The calculations revealed that in the second configuration, the temperature distribution on the surface of the panel-radiant heated floor system is relatively uniform and does not exceed the required value.
