Summary

The radiation characteristics of the frost layer (reflectance, transmittance and absorptance) were measured using three kinds of the radiative energy sources having various wavelength spectra. It was found that the monochromatic transmittance of the frost layer in the visible and infrared wavelength ranges was a law constant value. The reflectance and absorptance of the frost layer increased with an increase in the frost height and density; on the other hand, the transmittance of the frost layer decreased as those values increased. The reflectance, absorptance and transmittance of the frost layer on the melting process by radiative energy had the same tendency as on the frosting process in both visible and infrared-wavelength ranges.
