I'm sorry for sending so many suggestions in just one day, but I can't wait.
As described in the title, enclosed spaces should have insulation function. If the source of thermal radiation is within a closed space, it should be able to increase the temperature of a larger space, as compared to open spaces, thermal radiation is more difficult to lose. If the cooling source is located in a closed space, it should be able to lower the temperature in a larger space, as thermal radiation is more difficult to enter compared to open spaces.
