Environmental Control and Life Support System for Japanese Experiment Module

As a result of the preliminary study for the Environmental Control and Life Support System (ECLSS) of the Japanese Experiment Module (JEM), the functions of the JEM ECLSS are defined as follows: atmosphere control and supply, temperature and humidity control (including intramodule and intermodule air ventilation), atmosphere revitalization (CO₂ removal, contamination control and monitoring), fire detection and suppression, water management, and rescue provision, while the supply and recovery/processing of gas and water depend on the Space Station (SS) core ECLSS. Also, advanced technology developments for cabin air flow distribution system, regenerative CO₂ removal system, gas/water separating system, etc. were performed.
