Abstract

In this paper, the use of an uneven nodal network in floor heating simulation with finite difference heat balance method is examined. Two floor heating test cases, homogenous and multilayer floor, are presented. Temperature distributions on the floor surface and heat flows through the floor surface are simulated with even and uneven gridding approaches. It is shown that the total number of nodes can be reduced by placing the densest gridding in sections where the curvature of the temperature gradient is steepest.
