滑动门是否能在洁净区使用???
Which way should my doors swing?
Unless you have power-assisted doors, all doors should open into the room with the higher pressure. Double-leafed doors are notorious for causing the pressure differential balancing of rooms to drift off as the door springs gradually weaken and the doors leak air between rooms at levels outside of the design parameters. Annex 1, Clause 47 specifically states that sliding doors are not permitted in sterile plants as they typically create uncleanable recesses, projecting ledges and recesses. For these reasons they should not be used in non-sterile facilities either. 47. To reduce accumulation of dust and to facilitate cleaning there should be no uncleanable recesses and a minimum of projecting ledges, shelves, cupboards and equipment. Doors should be designed to avoid those uncleanable recesses; sliding doors may be undesirable for this reason. 4.2.8. Doors should be carefully designed to avoid un-cleanable recesses;sliding doors may be undesirable for this reason. Swing doors should open to the high-pressure side and be provided with self-closers. Exceptions are ermitted based on egress and site environmental, fire, health and safety containment requirements.
