Abstract : A portable water-conditioned suit system, employing a dry-ice cooler designed and constructed at the Naval Air Development Center and a commercially available water-cooled vest, was evaluated by exposing two sitting-resting subjects at sea level pressure to environments of 105F and 115F. Tests were conducted with and without the cooling system. Sublimation of approximately fifteen pounds of dry-ice kept the subjects relatively free from evidences of heat stress for periods of four hours at 115F. Based on a comparison with a wet-ice system, the dry-ice portable cooler, possessing significant advantages in terms of size and weight, produced equivalent cooling of the subjects. (Author)
