Abstract
An air revitalization system may include a humidity control device configured to remove water vapor from air within a pressurized enclosed volume. The system may further include an inlet duct configured to transport the air from the pressurized enclosed volume to the humidity control device. The system may also include an outlet duct configured to transport the air from the humidity control device to the pressurized enclosed volume. The system may include a sublimator configured to cool the air within the pressurized enclosed volume while generating additional water vapor. The system may further include a vacuum vent duct configured to transport the water vapor from the humidity control device and the additional water vapor from the sublimator to an exterior of the pressurized enclosed volume.
