Radiative cooling efficiency of white pigmented paints

Abstract Nocturnal temperature measurements of various infrared selective radiators performing radiative cooling have been carried out. Measured temperature differences between the radiators and ambient temperature were about 10°C. Radiating surfaces have been prepared by applying different kinds of paints on aluminium substrates. It was shown that the addition of a BaSO4 extender in the paint dispersion increased the cooling performance of the paint radiators. Comparisons between predicted cooling performances by calculations and measured ones are discussed in detail.
