Sažetak
Wetsuits are designed to protect divers from underwater environment and to reduce the thermal shock that may happen during the stay in the cold water. When the body is immersed, the heat transfer by conduction occurs between the and surrounding water. In comparison to the air, the thermal conductivity of water is 25 times greater. Water also has ability to absorb body heat approximately 3500 times greater than air of the same volume. In the water, the heat transfer trough convection is caused by currents or due to movements through the water. It also needs to be pointed out that the heat transfer by convection is significantly higher in windy conditions and when waves are intensive. Wetsuits are typically worn where the temperature of water is in the range 10- 25°C. They provide thermal protection that depends of the level of fit, meaning that suit that is too loose on the body may not be thermally efficient. Such suits have some additional limitations among which should be pointed out the fact that water can enter the suit and increase the level of thermal discomfort. In this investigation, IR thermography is used to observe the changes in skin temperature of divers wearing neoprene diving suit immersed in sea water. For the measurement is used thermal camera FLIR E5. In the paper are discussed the regional changes of the skin temperatures due to immersion. The outcomes of research will facilitate the process of designing wetsuits in order to increase/decrease thermal insulation in the zones that are identified and finally to maintain optimal thermal comfort.
