چکیده
The paper presents a short characteristics of hyperbaric environment in which saturated divers are present with particular attention to the influence of thermalphysical properties. The above properties play the important part in the body's functions. They support the divers with comfort and security as well. On the example of a decompression chamber, chosen problems concerning thermal phenomena connected with plotting the energy balance are presented.
