Abstract:

Two evaporative beverage chiller prototypes were tested against a control for performance, water temperature perception and overall hydration. Thirty-four Marines were separated into three groups for this 6-day between-groups test. Each group tested one of the three conditions battery powered, non-powered, or control hydration system with neither chiller for a period of 2 days. After 2 days, each group rotated to a different condition. Each group consisted of approximately 10 Marines. The three conditions were counter balanced to control for order effects. The average number of hydrations bags consumed per Marine per day increased from 1.1 to 1.6, an increase of approximately 1.5 L of water. Most Marines reported overall satisfaction with the prototypes aside from some design flaws that made them either too large or too easily broken.
