Practical cooling capacity estimation model for a suspended metal ceiling radiant cooling panel

The main thrust of this research was to develop a simplified cooling capacity estimation model for a suspended (free-hanging type) metal ceiling radiant cooling panel. By statistically analyzing panel performance data generated by a validated analytical panel model, the impact of various design parameters and their combinations on the panel cooling capacity was estimated. And then a linear regression equation was derived as a function of major design parameters and interactions which have significant effects on the panel capacity. In this analysis, eight single parameters and 13 two-factor interactions showed significant impact on the panel cooling capacity. Consequently, a simplified regression model for a free hanging panel was derived as a function of those selected parameters. The proposed model could estimate the panel cooling capacity not only for the natural convection but also for the mixed convection condition present in a mechanically ventilated space.
