Visualization of overlapping of scanned areas at mean radiant temperature measurement

Abstract

This contribution deals with visualization of overlapping of scanned areas at mean radiant temperature (MRT) measurement. Mean radiant temperature is parameter used in thermal comfort determination and has the strongest influence on thermophysiological comfort indices (e.g. Predicted Mean Vote index) (Auliciems, 2007). Our solution uses thermopiles instead of globe thermometer that is usually used. We use the thermopiles because of known globe thermometer problems in MRT measurements like disability to measure asymmetric radiation, high time constant and other. Thermopile sensor scans particular angle with output signal depending on angle of incidence. This article shows how well is the whole scanned area covered and if any blind spaces exist.
