Particle Concentration Comparison of Radiator and Floor Heating Systems under Zero Air Change Rate Condition

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