Experimental Study of Heat Performance on Ceiling Radiant Cooling Panel

摘要

The main thrust of this research was to develop a simplified correlation between the heat flux density and temperature difference firstly.To obtain the limited values of the total heat transfer coefficients based on the experimental data secondly.The climatic test chamber with a cooled ceiling radiant panel composed by three different construct wayswas constructed.Based on the experimental data,a linear regression equation was derived.Besides,a comparison with previous correlation and data given in reference literature was conducted.The result shows that the heat flux destiny can be quantified in different radiant panel structures.The total heat transfer coefficients are different with the selected reference temperature.The experimental results can provide guidance for engineering applications.
