Wall, system of highly clean rooms, production method thereof and construction

A system of highly clean rooms, comprising:

• at least one room,
• at least one of the walls constituting the room being constituted of a wall with an internal space capable of introducing air for a room, airways communicating the outside and the internal space being provided on the edge of the wall, at least one of major surfaces forming the internal space being made of a membrane not passing through dust particles but passing through gas molecules,
• the room being configured so that the room is provided inside with a living space as an enclosed space, there is no movement of air as an air current between the inside and the outside of the living space, air is introduced into the internal space of the wall from the outside space enclosing the room through the airway of the wall, the room is provided with the first fan filter unit provided with a blow opening so as to supply gases inside the living space, at least one opening corresponding to an absorption opening of the first fan filter unit is provided in at least one of the lateral walls of the room, all of gases flowing inside the living space from the blow opening pass through the opening and a gas flow path airtightly communicating the absorption opening and the opening and fed back to the first fan filter unit,
• the room being provided with doorways capable of moving in the living space,
• the membrane having the area A set by scaling of {(V/A)/(D/L)} where V is the volume of the living space, A is the area of the membrane, L is the thickness of the membrane, and D is the diffusion constant of oxygen in the membrane,
