Applications and Measurements Methods of Radiant Heat Exchange of the Human Body

摘要

Radiant heat exchange between humans and their environment has not received much attention. Recently, new technologies have emerged that would allow engineering of emissive, reflective and even transmissive properties of clothing. In this paper an overview of the principles of radiant heat exchange will be discussed and the consequences of these to clothing design explained. Novel emissive, reflective and transmissive properties can thus be judged on their expected added value. Furthermore, the data will show how thermal infrared cameras can be used for analysis of clothing insulation and human heat exchange. These results will further support specific fabric engineering to optimize radiant heat exchange in a wide variety of conditions, with a appropriate understanding of effects of color and wavelengths in the ElectroMagnetic spectrum.
