Summary: | Heat-related illness is a critical factor for personnel operating in high heat environments. Traditional cooling technologies are limited by the need for a power supply, the added weight of the product, and the cooling duration. This research investigates a lightweight (47-g), passive cooling textile material provided by Arctic Ease(registered) (Phoenixville, PA) and designed by the United States Air Force School of Aerospace Medicine (USAFSAM/FHC) that offers multiple hours of sustained cooling. The ability to deliver cooling was evaluated using a thermal manikin. Initial research was conducted under dry heat conditions at 35 deg C/50% relative humidity as the first step to evaluate the technology. Effective cooling rate was determined to be 30 W for the system. Calculations were based on the manikin zones covered by the shirt. Preliminary dry tests indicated a cooling duration longer than 2 hours. |
