Quantitative Estimation of Nitrogen Losses in the Atmosphere of a Hermetically Sealed Inhabited Object

The paper presents a methodology for determining nitrogen losses from the atmosphere of hermetically enclosed inhabited objects. Loss of the atmosphere consists of two parts. The first part of losses occurs when the object is locked with the transportation device. In this case, atmospheric gas leaks from the inhabited premises of the facility into the airlock. The second part of losses is associated with the operation of adsorption apparatus designed to remove carbon dioxide and water vapor from the atmosphere of a hermetically sealed inhabited object. In this case, atmospheric loss occurs due to the presence of a “dead” volume in these devices. Calculated estimates of nitrogen losses showed that the atmospheric losses for the two parts are comparable.
