- Mit einer Thermopuppe wurde die Erwärmung durch langwellige Wärmestrahlung beim Tragen von Schutzkleidung erfasst, wobei Material und Anzahl der Schichten der Unterbekleidung variiert wurden. Die Unterbekleidung minderte die durch Strahlungs-Absorption hervorgerufene Erwärmung. Die dabei beobachtete hohe negative Korrelation mit der thermischen Isolation zeigt Möglichkeiten zur Berücksichtigung von Effekt modifizierenden Eigenschaften wie Materialdichte oder -dicke bei der Modellierung auf.

Tidskriftsartikel (refereegranskat)abstract
- This report considers results of an ED funded research on thermal properties ofprotective clothing and their use in the assessment of the thermal strain at work. In order to study the effects of the asymmetry oflong wave thermal radiation on the heat transfer through protective clothing, the heat loss under all-side and unilaterally applied radiation with the same incident radiant power of 279 W/m2 was measured with a thermal manikin and compared to a reference condition where mean radiant temperature was equal to air temperature. With exposure to radiation a lowered heat loss, i.e. heat gain for the whole covered body area was observed, which did not depend on radiant asymmetry for the dry as well as for the combined dry and evaporative heat loss, and which was attenuated when wearing a more insulating underwear. However, under one-sided radiation a more inhomogeneous spatial distribution occurred with higher heat gains and higher surface temperatures at the irradiated body parts. Practical Relevance The direction ofthermal radiation in the horizontal plane may be neglected when assessing the physiological heat strain in protective clothing by heat budget models. In contrast to this, it may be advisable to consider radiant asymmetries with respect to thermal comfort with low intensity radiation, and the most intense radiant source when assessing the risk of skin burns.
