Szacowanie wpływu izolacji tułowia na temperaturę skóry człowieka i odzieży w zimnym otoczeniu przy zastosowaniu termografii w podczerwieni
Języki publikacji
Abstrakty
The study presents experiments, conducted with human subjects in an artificial cold chamber, assessing the influence of a cold environment on the temperature of the human body. Infrared thermography was applied as a non-invasive, contactless method for direct measurement of the temperature distribution of both clothed and uncovered parts of the body. Two subzero temperatures were applied and clothing ensembles with two different clothing insulation values were used to assess the effect of the clothing insulation of the torso on the temperature of clothed and uncovered parts of the body of the participants. The average temperature of the chest, back, upper arms, face and middle finger is presented and discussed in relation to the cold exposure duration and clothing insulation used. The results obtained showed the strong influence of the clothing insulation over the torso on skin and clothing temperatures of the body and overall cooling of the body in subzero temperatures.
W artykule przedstawiono wyniki eksperymentów przeprowadzanych z ludźmi w sztucznej komorze chłodniczej. Oceniono wpływ zimnego otoczenia na temperaturę ciała człowieka. Termografia w podczerwieni została zastosowana jako nieinwazyjna, bezdotykowa metoda bezpośredniego pomiaru rozkładu temperatury zarówno zabezpieczonych odzieżą, jak i niezabezpieczonych części ciała człowieka. Zastosowano dwie temperatury ujemne i zestawy odzieżowe o dwóch różnych wartościach izolacji w celu oceny wpływu izolacji odzieży na temperaturę ubranych i niezabezpieczonych części ciała uczestników. Przedstawiono i omówiono średnią temperaturę klatki piersiowej, pleców, ramion, twarzy i środkowego palca w odniesieniu do czasu trwania ekspozycji na zimno i izolacji zastosowanej odzieży.
