This book was released on 1966 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1969 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was carried out to verify the feasibility of controlling carbon dioxide levels in space cabin atmospheres by freeze-out techniques using thermal radiation as the only mode of heat rejection. A one-tenth scale system was constructed with the primary aim of gaining understanding of the CO2 precipitation mechanism and determining the operating characteristics of a precipitator plate. Both quantitative measurements and visual observation of the frost formation were made. The geometric characteristics of the precipitator channel were found to be not critical. Uniform frost layer formation could be obtained and premature channel plugging was not a problem. Typical precipitator plate effectivenesses of 0.75 - 0.85 were easily obtainable. Simultaneous CO2 sublimation was achievable at a controllable rate. System stability was easily achieved. Solid CO2 carryover in both the precipitating and sublimating streams is a real possibility and preventive measures must be taken in the final design of the system. Based on these results, a complete test system was designed to handle the water vapor and carbon dioxide loads in a one-man, manned space enclosure. The system, with a total weight of 51.2 lb, is a two-loop configuration where one loop maintains humidity control and the other removes the generated carbon dioxide and returns all of the accompanying water vapor to the cabin. The system will operate indefinitely with no operator intervention, is operable in zero-gravity, and is of low weight, volume, and power. (Author).

Download or read book Climate Change written by The Royal Society and published by National Academies Press. This book was released on 2014-02-26 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate Change: Evidence and Causes is a jointly produced publication of The US National Academy of Sciences and The Royal Society. Written by a UK-US team of leading climate scientists and reviewed by climate scientists and others, the publication is intended as a brief, readable reference document for decision makers, policy makers, educators, and other individuals seeking authoritative information on the some of the questions that continue to be asked. Climate Change makes clear what is well-established and where understanding is still developing. It echoes and builds upon the long history of climate-related work from both national academies, as well as on the newest climate-change assessment from the United Nations' Intergovernmental Panel on Climate Change. It touches on current areas of active debate and ongoing research, such as the link between ocean heat content and the rate of warming.
