The rugged, epoxy coated case is beneficially strong and sturdy. Being quite compact, but extremely durable, corrosion-resistant and highly-efficient, it perfectly fits both commercial and household purposes. This powerful, industrial heater is a great choice, suiting large premiums, like warehouses or multi-vehicle garages, shops, basements, exposed areas.

Now if you have a vacuum there is no capacity or conductivity because there is nothing to transfer the heat. So far heat was always transferred between different mediums according to their thermal capacity and conductivity. In ONI, however, this is probably just an engine limitation or a simple design decision to not make the system overly complicated to code. Which means that, as you already said, Space stations lose their heat because of radiating this heat out. This shiny coating reflects the heat radiation like a mirror and keeps it either inside the bottle (if the content is hot) or outside (if the content is cold). And this is the second secret of the vacuum bottle (or thermos): while the vacuum suppresses heat exchanges by conduction and air convection, exchange by radiation is suppressed by the shiny metallic coating of the bottle. The amount of heat that a spacecraft radiates into space and receives from the Sun can be controlled by the makeup of its surface. A spacecraft is roasted on the side that faces the sun and very effectively cooled on the opposite side. Without any star or planet nearby the temperature of space (as defined by radiation) is 3 K (-270 centigrade), the temperature of the ubiquitous background radiation from the Big Bang, i.e. Of course, the cold air around you plays a role, but if there is no wind, the major heat exchange is radiation. The fire radiates heat at you, and your back radiates heat into the cold night. Have you ever stood in front of a campfire on a very cold winter night? While facing the fire you may feel roasted in your face, while your back feels frigid. However, that is a quite powerful means of exchanging heat. Space is a vacuum, and heat can only be exchanged through radiation.
You remember your college physics correctly. If I am incorrect, then how does a vacuum bottle keep things hot or cold? The only form of heat dissipation would be radiational and that would not be enough to cool an astronaut in a space suit - they must require some form of air conditioning. Doesn't a true vacuum have no temperature? It would seem that the only problem that the astronauts should have is getting rid of heat. If I remember my college physics and astronomy correctly, space is a vacuum. NASA frequently refers to "the cold of space" and the extremes of temperature from the sunny side of the shuttle to the shaded side. To your comparison to the "real world", I found this Q&A of NASA and question 5 is probably what you are looking for. Heat up a medium a lot and then dump it into the space biome. This something that happens the same with a regular vacuum space somewhere in your world.įor you to "vent" steam into space you must do exactly that. However, since Space is a vacuum there is nothing the heat can be transferred to. So if you have hot water and you pipe it with a radiant pipe through another liquid then the other liquid needs to be cooler to suck up the heat from the liquid in the radiant pipe. For heat to transfer you need a medium that is at a lower temperature as the other medium you want to change the temperature of.
