Abstract:
Subfloor heating and cooling systems in residential and commercial buildings present advantages from the point of view of comfort conditions and energy saving. In the present work a two dimensional and a three dimensional model for subfloor heating and a two dimensional model for subfloor cooling, using the Fluent software based on the finite volume method were developed. From the point of view of exergy destruction as we may have lower temperature difference between the heating medium and space, we come up with less exergy destruction. To determinate the optimum working conditions of these systems, a numerical model for subfloor heating and cooling is presented. Different methods of modeling and boundary conditions are also evaluated and the results are compared. According to the results, it can be concluded that the Neumann boundary condition has some advantages over the Dirichlet boundary condition from the point of view of uniform temperature distribution which provides better comfort condition. Also a suitable model for subfloor cooling systems is presented
