Abstract
A study is being conducted on the design, development, fabrication, integration, and testing of subsystems for an advanced extravehicular mobility unit portable life support system for evolutionary Space Station Freedom or other applications. The subsystem discussed in this paper is the heat rejection system (HRS). The function of the HRS is to remove metabolic and equipment heat loads and provide a comfortable thermal environment for a crewperson during extravehicular activity.
The HRS comprises a radiator and a water evaporator. Use of this HRS results in the venting of the evaporated water. This combination of components, however, offers a significant reduction in water usage compared to a standalone evaporator or sublimator, and a significant reduction in weight compared to nonventing configurations.
