Abstract:

Various freeze-out techniques, conceived for controlling carbon dioxide and water vapor in a manned space enclosure in earth orbit, were investigated, analyzed and evaluated. Carbon dioxide elimination presents a much greater problem than does water vapor elimination. The system selected has the following main characteristics a separate air loop for each vapor simultaneous sublimation and precipitation in each loop the freeze-out plate, sublimator, radiator, and second stage heat exchanges in the carbon dioxide loop, are integral and outside the cabin in an equatorial orbit, the radiator is sun-shielded by a fixed-attitude, open-ended cover.
