this citation summarizes a one-page announcement of technology available for utilization. a bench model, dry-ice, liquid-pulsepump, portable cooling system, developed by the navy clothing and textile research facility provides conduction cooling to personnel subjected to heat stress. the system, small and light enough to carry, dissipates heat loads greater than those created by personnel performing light to moderate work activities and requires no electrical power source. a unique feature of the system is the use of the carbon dioxide gas given off by the dry ice as it sublimes, when cooling the heat transfer liquid and from ambient heating, to power the pump which circulates the liquid between the dry ice heat exchanger and liquid cooling garment. the system has potential application in many situations where heat stress to personnel is known to occur. for instance crashcrew firefighters can be debilitated by the heat when dressed in their turnout clothing during runway standby operations in warm climates. in the event an emergency fire condition occurred during this time, their ability to perform effectively would be questionable
