Abstract: A novel radiant cooling technology is under development that allows the panel’s chilled surface to operate below the dew point of the surrounding air without condensing air moisture. This is achieved by separating the chilled surface from the humid air using a thin infrared-transparent membrane. This paper outlines the development of a generic steady-state heat transfer model used in the parametric design of future panel applications. The model is calibrated against experimental data gathered in Singapore and can ac curately predict the temperature of the membrane with an average offset of 0.3◦C from the true membrane temperature under different operating condi tions. Membrane temperature of such a radiant cooling system is one of the most critical predictive outputs of such a panel’s heat transfer model as panel temperature must be controlled in order to mitigate condensation risks.
