Abstract
Variable emissivity electrochromics have been proposed as an enabling technology for integrating a radiator capability into a space suit in order to augment or replace the traditional means of heat rejection achieved via water sublimation. Thermal analysis was performed to establish design trade spaces and to provide operational guidelines and performance specifications for electrochromic technology development. Based on using the available surface area of an entire space suit as a radiator and the projected infrared emissivity modulation capability of state-of-the-art electrochromic material, the proposed application for space suit heat rejection suggests the potential exists to reduce or eliminate reliance on water consumption for thermal control within a defined range of metabolic and environmental boundary conditions.
