Abstract

In the present study, we examined panelinvolved energy transmission (convection, radiation and conduction) through a test version of a panel heating and cooling system, created by attaching ducts to a metallic panel. Tests were conducted during both heating and cooling. Furthermore, numerical analysis of the test panel was conducted using the finite element method to predict panel surface temperature distribution, amounts of heat removed, etc. The results of prediction by this method agreed well with the results of actual measurement. When the data yielded by three-dimensional numerical analysis were compared with those yielded by two-dimensional numerical analysis, there was little difference between the twosets of data. This indicates that two-dimensional numerical analysis is useful for prediction of panel thermal profiles.
