摘要： Provided are a system of highly clean rooms capable of continuously maintaining high cleanliness of air of class 1 or above and supplying enough oxygen inside the room for several persons to live in and a wall adapted to the structure of such a system. The system of highly clean rooms 10 is provided with a living space 6 and a space 5 between the roof and the ceiling as subspaces of an enclosed space formed by a room 1a. One of the lateral walls of the room 1a is constituted of a wall 9 with an internal space 7, which is a hollow wall. The internal space 7 and the living space 6 are in contact via an inner wall 9a of the wall 9, and a gas exchange membrane 26 is stretched in the inner wall 9a. Furthermore, a gas flow path 24 is provided inside the inner space 7 and the gas flow path 24 allows airtight communication between an opening 23 provided on the lowest part of the internal wall 9a and a gas entry opening of a fan filter unit 21 provided on a ceiling wall 2a inside the space 5 between the roof and the ceiling.

摘要： A room 100 in a building has a living etc. space 101 of volume V that is an enclosed space. Ventilation of an air flow F is performed from the outside to the living etc. space 101. Entering/exiting of air as an air current between the inside of the living etc. space 101 and the outside is eliminated, and at least a part of the boundary between the living etc. space 101 and the outside is configured from a gas exchange membrane 310 having a diffusion constant D, a thickness L, and an area A for gas molecules of interest. When air inside the living etc. space 101 is sufficiently agitated and the concentration of gas molecules constituting the air is made spatially uniform, η(t) is controlled so as to vary according to η ⁡ ( t ) = η o - BL AD ⁢ ( 1 - exp ⁡ ( - [ AD ⁢ / ⁢ L ] ⁢ t ⁢ / ⁢ V ) ) ( 9 ) B(m3/s) is the gas consumption amount inside the living etc. space 101, η1 (t) is the gas concentration inside the living etc. space 101 at time t, and η0 is the gas concentration of the outside.
