Abstract:
1. A device for collecting moisture contained in exhaled air of a worker who works in a dry room and returning the collected moisture to the worker together with inspired air, the device comprising: a cover unit adapted to be fixed to a head or a neck of the worker for covering at least a region of nose and mouth of the worker so as to collect the exhaled air of the worker, the cover unit having an exhaust opening and an air supply opening; a moisture recycle unit with an adsorption unit, the moisture recycle unit adapted to be worn by the worker for simultaneously performing two processes of an adsorption process and a regeneration process, the adsorption process consisting of taking in moist air, adsorbing the moisture contained in the moist air on the adsorption unit, and emitting the resulting dry air, the regeneration process consisting of taking in dry air, evaporating the moisture adsorbed by the adsorption unit into the dry air, and emitting the resulting moist air; an exhaust hose for connecting the exhaust opening of the cover unit and the moisture recycle unit; and an air supply hose for connecting the air supply opening of the cover unit and the moisture recycle unit, whereby moist air exhausted into the cover unit is dehydrated through the moisture recycle unit and the resulting dry air is emitted into the dry room, while dry air taken in from the dry room is humidified through the moisture recycle unit and the resulting moist air is supplied into the cover unit.
