Abstract |
A compact battery-powered beltpack cooling unit was developed to deliver filtered ambient air to the face and body. The device was tested on seven subjects wearing chemical protective clothing who performed exercises in a thermally controlled chamber under different experimental conditions. Intermittent cooling (air conditioned cooling during rest periods but no personal cooling during work cycles) and continuous air cooling (personal cooling during work cycles and conditioned air cooling during rest periods) resulted in significant reductions in rectal temperature, mean skin temperature, and heart rate compared with the no-cooling conditions. The continuous air-cooling trial significantly improved thermal comfort and sweat evaporation. |
