Abstract:

In this study, in a floor heated room, optimum natural convection heat transfer over the floor is analyzed numerically for constant specific conditions such as; emperature of supply water, design temperature, outside temperature, thickness of concrete on water tubes, distance between water tubes and, etc. In this condition, an optimum heat transfer coefficient of air always exists for which maximum heat transfer fromthe floor takes place. In this paper, above parameters are introduced and the effect of thickness of concrete on heat transfer is investigated. Subsequently, the effect of different amounts of convection heat transfer coefficient of moving ambient air on the obtained heat transfer from the surface of the concrete is studied.Results showed that that thickness of concrete has a great effect on fluxes of energy obtained from the coverage, ex. marble. And by using less thickness of concrete, more fluxes of energy is obtained. Also, consequences are noted that by different amounts of mentioned parameter, various amounts of thermal energy from the surface of the concrete are available.This optimum convection heat transfer coefficient can be obtained through an electrical fan to get a more economical thermal power from the surface.
