I'd like to suggest the merging of Elektron (ISS), Oxygen Generating System and Air Revitalization System into this article, as they are small, stub articles that don't particularly need to be standalone, and would be better served as sections here. I'd also like to suggest Life support system#International Space Station is merged here, as most of its content is duplicated both here and at the main ISS article. I also think that the paragraph on life support systems at Zvezda (ISS module) could be moved here, and a section written up on the Chemical oxygen generators used on ISS. As always, comments are greatly appreciated. Colds7ream (talk) 14:25, 18 January 2010 (UTC)
Hmmm. It appears the merger has put information into this ISS-related article that has nothing whatsoever to do with the article, or the ISS. I have tagged the first bit of it, so it may be removed in due course if no relevance is shown. N2e (talk) 20:17, 9 December 2010 (UTC)
There appears to be no description of the ISS system(s?) for waste heat dissipation into space in any Wikipedia article. How big is it? How much heat can it dissipate into space? How much power does it take to run it? What is the mass of the waste heat rejection system? Etc. Does anyone have a good source for this? N2e (talk) 20:04, 9 December 2010 (UTC)
"The four components used in the Passive Thermal Control System (PTCS) are insulation, surface coatings, heaters, and heat pipes.
"The Active Thermal Control System (ATCS) is required when the environment or the heat loads exceed the capabilities of the PTCS. The ATCS uses a mechanically pumped fluid in closed-loop circuits to perform three functions: heat collection, heat transportation, and heat rejection.
"Inside the habitable modules, the internal ATCS uses circulating water to transport heat and cool equipment. Outside the habitable modules, the external ATCS uses circulating ammonia to transport heat and cool equipment."
