Modelling of the Nnormobaric and Hyperbaric Facilities Ventilation

Abstract

This paper is the result of many work and research programs. During the execution of the projects, it was proposed a new mathematical model of the process of ventilation of a semi-closed rebreather. Its validation required making a special simulator of gas exchange in the breathing process. Use of the device made experimental validation of the proposed model possible. This model has been adjusted to the process of ventilation in hyperbaric chambers. The validation process required developing a new type of carbon dioxide emission simulator. The generalization of the adopted method for the submarine ventilation process was only an obvious consequence of earlier considerations. However, the validation process required to undertake extensive research on a real object, which confirmed the validity of the modelling method adopted. The research on ventilation of the mining excavation constituted the validation of the adopted research approach. In typical residential and public buildings, similar methods have been used relatively recently. In general, they involve air-conditioning of the sealed buildings. This entails the need to regenerate the respiratory atmosphere inside, making them similar to military facilities. Methods of protection against contamination can be used with regard to atmospheric pollution, especially in the work environment. As in the case of military facilities, the methods of modelling ventilation in standard and hyperbaric objects described here would allow developing more accurate methods to design and use ventilation and air-conditioning systems in buildings.
