Population

Thermal manikin in a climatic chamber

Exposure conditions

PCM melting temperatures of 24, 28, and 32 °C with manikin temperatures of 34 and 38 °C. Measured across the available PCM cooling period.

Outcome measured

Cooling rate and duration as functions of temperature gradient, mass, covering area, and latent heat

Limitations

Thermal-manikin research on generic cooling vests in hot conditions. It does not establish The Ice Sack cooling profile or human outcomes.

Cold-delivery methods differ in medium, contact, coverage, temperature profile, and heat-transfer conditions; results from one method should not be assumed to transfer directly to another.For PCM cooling garments, cooling rate and duration depend on variables including temperature gradient, covering area, PCM mass, and latent heat.
