The body temperature of a diver is one of the most important aspects of the concept of underwater safety and comfort. The heat balance equation previously established, was improved in this paper by introducing a linear dependence of the absolute humidity on the body temperature, as the absolute humidity influences the latent heat flux needed for the humidification of the breathing gas. The solution of the new proposed heat balance equation is a step forward in assessing the body temperature in both cases of unitary and saturation diving. The paper presents the equation and its solutions in the case of breathing either air or Heliox and compares the theoretical results with the values measured in the frame of simulated saturation diving with Heliox 5/95, in the hyperbaic laboratory. The proposed equation predicts the body temperature of the diver, at the end of a 30 minutes immersion with a good accuracy. The relative error is up to 1%.

The major multi-annual project of the Romanian Naval Forces Polygon for the training of professional divers, developed within the Sectorial Research and Development Plan of the Ministry of National Defense, initiated in 2020, was continued in 2021 by the research team of the Diving Center in Constanţa, by configuring the main work modules. The paper presents the technical development of the capabilities and the solutions of location of the main equipments for each of the 4 modules, respectively Module 0 (the surface), Module 1 (5-7 m deep), Module 2 (15-17 m deep), and Module 3 (20 m deep).
