A simplified model for radiant heating and cooling panels

Abstract Radiant panel heating and cooling systems for sensible space conditioning have several attributes. These include, but are not limited to, energy savings potential and ability to favorably tie-in with moderate temperature, low-intensity energy sources like solar systems and heat pumps. In order to predict and incorporate such attributes of panel systems, a comprehensive, yet simple model is necessary so that the designers will find it practical to use. Part of this model is the heat diffusion in the panel. An analytical heat diffusion model was developed which is applicable to heating and cooling. Sample designs indicated that this model has an accuracy comparable to that of a finite element model and can be used easily by the design engineer for practical purposes.
