This paper contains a review of the requirements and design of the Environmental Control and Life Support System (ECLSS) for Space Station Freedom; a review of an ECLSS computer program model developed at Boeing for the complete configuration of pressurized elements or volumes; and some significant computed results from this model showing transient performance for subsystems responsible for Temperature and Humidity Control, Atmosphere Control and Supply, Air Revitalization, and Water Recovery and Management. The model referred to is a comprehensive ECLSS Model which has been developed using the G189A Environmental Control System simulation tool.(1)*. The development and potential application of the Model was presented at the 1989 ICES Conference (2). The Model has since been slightly revised and extensively operated, to obtain information regarding nominal and off-nominal ECLSS conditions onboard Space Station Freedom.
