Experimental Study of Heat Performance on Ceiling Radiant Cooling Panel

AbstractThe main thrust of this research is 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 ways are constructed. Based on the experimental data, a linear regression equation is derived. Besides, a comparison with previous correlation and data given in reference literature is conducted. The result shows that the heat flux destiny can be quantified independently in different radiant panel structures. The total heat transfer coefficients are fluctuated in some ranges. The experimental results can provide guidance for engineering application
