Backgrounds of thermodynamic design calculations for living accommodations in underwater research complexes

Abstract

The paper presents shortly characteristics of a hyperbaric environment, which saturated divers stay in, and of thermal-flow phenomena occuring in it. Such an environment is distinctly different from the earth atmosphere. Thermophysical properties of compressed breathing mixtures can disturb, apart from their physiological impact on the human organism, its regular functioning, as well as facilities and systems which have to assure divers’ comfort and safety. The theoretical and experimental research works, performed by the Chair of Thermal Engineering, Technical University in Szczecin and reviewed in this paper, make it possible to highlight some poorly recognized thermodynamic processes which occur in compressed breathing atmospheres. Application of the results can be helpful in carrying out further research and designing new saturated diving systems.
