PHYSIOLOGICAL EVALUATION OF A FREE-FLOODING DIVER HEAT REPLACEMENT GARMENT.

摘要

The general capabilities of a free-flooding heat replacement garment in maintaining thermal comfort in 40F water,at both surface and deep diving conditions,are considered. Suit inlet and outlet temperature,flow rate,skin and rectal temperatures,and divers'subjective comfort level were recorded. Suit inlet temperatures which produce a subjective response of thermal comfort by the diver (Comfort Zone Inlet Temperature) at various flow rates are presented for surface conditions and through use of a heat balance equation,for depth conditions. While the suit is considered inefficient because of its high power requirements,especially at depth,its wearability and mode of heat transfer make it an excellent heat replacement garment. (Author)
