>>6716912>But you still have to produce the iceThe ice isn't "made." It naturally forms when liquid water is exposed to space. The liquid water comes from the Space Shuttle / Space Station.
>which creates heat, that has to go somewhere. This system, which is meant to manage heat, requires heat which is not explained for.The astronaut suit is not a fully closed system. If it is not hooked up to a station that provides the suit with water, the astronaut will overheat and die. Going back to our analogy in the summer, where did you get the ice cube from? You didn't "make" it yourself, you got the icecube from a refrigerator in your house that is powered by a municipal plumbing and a coal fired generator.
>Where does the heat that was in the water go when it freezes? How does this system work without creating heat in the form of energy doing work? What you are describing sounds impossible.Let me lay this out again, I think you've got it backwards. It's not freezing, it's sublimating:
1. Water from the space shuttle feeds into the spacesuit backpack.
2. Some water is allowed to be exposed to space, it turns into a thin sheet of ice.
3. There is now a thin sheet of ice on the spacesuit's backpack.
4. The refrigeration system collects the astronaut's heat.
5. The refrigeration system dumps the heat into the thin sheet of ice.
6. The thin sheet of ice absorbs this heat and and sublimates into vapor.
7. The vapor leaves the spacesuit, thus carrying away the heat energy.
