Abstract

As a result of isolating doors and windows very well to reduce heating energy costs, some environments' air change rate becomes zero. Two different heating systems (radiator and floor heating systems) widely used in residential applications were compared for a room where the air change rate is zero, using numerical methods in terms of particle concentrations. 3D dimensional CFD simulations show that the floor heating system performs better in removing the pollutants dispersed homogeneously in the room, while the radiator system is more effective in removing the pollutants emitted from a source close to the floor. It was concluded that special care should be taken not to have a source of pollutants close to the ground surface in the environments where a floor heating system is used.
