Inter-Module Ventilation Changes to the International Space Station Vehicle to Support the Bigelow Expandable Activity Module

摘要

The Bigelow Expandable Activity Module (BEAM) was berthed to the International Space Station (ISS) as part of a two year study on the feasibility of expandable volumes for habitability. The BEAM is not outfitted with heaters for thermal control of the wall surfaces. To ensure that the module remains above the station dew point Environmental Control and Life Support System (ECLSS) Inter-module Ventilation (IMV) must be maintained between the Node 3 volume and the BEAM. This paper will describe the details, challenges, and modifications to the ECLSS on ISS and their interaction with BEAM.
