Résumé

The main thrust of this research was to develop a simplified cooling capacity estimating correlation for a top-insulated metal ceiling radiant cooling panel (CRCP). By statistically analysing the impact of various panel design parameters on the panel cooling capacity, a linear regression equation was derived. A validated analytical CRCP model was used to collect panel performance data for the various combinations of design parameters. It was found that eight single design parameters and eleven two-factor interactions significantly affect the panel cooling capacity. Consequently, a first-order linear regression equation, or the simplified CRCP model, was derived as a function of the major single parameters and two-factor interactions. The proposed model returns the cooling capacity of a top-insulated CRCP not only for the natural convection condition but also for the mixed convection condition present in mechanically ventilated spaces. The predicted panel cooling capacities for both aluminum and steel panels corresponded well with the manufacturer's data and experimental results reported in the literature.
