要約

Thermal exchange models are described for high pressure helium-oxygen environments and are used to predict the ambient temperature required for thermal balance and the magnitude of the convection, evaporation, radiation, and respiratory heat losses at depth to 47 atmospheres. The predicted values for comfort temperatures are compared with reported operational values and correlate reasonably enough to justify confidence in the basic model. Further refinement of the equation awaits actual data on transport and thermo-physical properties of breathing gas mixtures at pressures to 100 atmospheres.
