Considering the increased need to test and develop ventilation both for normobaric and hyperbaric use in underwater technology industries (diving equipment, submarines and other underwater facilities), mining, and other relevant industries, this book presents a complete study in the field of normobaric and hyperbaric ventilation. It focuses on development and verification of the research-based mathematical modeling approach for deterministic modeling of ventilation processes, both for objects with semi-closed and closed circulation of breathing gas. It also proposes validated analytical models of ventilation processes, and a new type of carbon dioxide emission simulator that was also developed.

This book is aimed at researchers, professionals, and graduate students in hyperbaric facility processing, building ventilation processing, life support system design, shipbuilding, marine engineering, and diving submarine safety.

Part I

Diving Apparatuses

Modeling of the diving apparatus ventilation process is the basis for planning the adequate decompression of the diver during his/her exit from the environment with higher pressure. Determining an adequate model of respiratory space ventilation is particularly important for devices with semi-closed circuit of the breathing mix.

The first part describes the research on ventilation of various types of respiratory system construction. The presented deterministic modeling method was later generalized and used to model the ventilation process of other objects, such as submarines, hyperbaric complexes, or mining excavations, which is described in further parts of the monograph.

1 Ventilation of the Construction with a Constant Dosage System

Most of the old research results presented were from experimental investigations of the German construction of the underwater breathing apparatuses UBA type FGG III, a semi-closed-circuit rebreather SCR using a constant dosage of premix¹ gas mixture, prototypes of the Polish SCR-UBA type GAN-87 using a constant dosage of premix, and the self-contained version APW-6M SCUBA (Kłos, 2000). Newer scientific investigations concentrated on the...
