在医院建筑里,电梯竖井与地下室相通。譬如说,有这样的情况,饮食部的食品沿地道输送到医院的地下室,然后进电梯运至上面各层。因此电梯前室的空气必须保持正压20Pa。电梯前室同其它房间、走廊用非燃材料制成的密实隔板间隔开,与走廊连通的门应该是自动关闭的,门洞尺寸按建筑设计,门缝隙面积为(?)式中 (?)-门洞周长,m;

In a hospital building, the elevator shaft communicates with the basement. For example, in this case, food from the food and beverage department is transported along the tunnel to the basement of the hospital and then transported into the elevator to the upper floors. Therefore, the air in the elevator front room must maintain a positive pressure of 20Pa. The front room of the elevator is separated from other rooms and corridors by a solid partition made of non-combustible material. The door connected to the hallway should be automatically closed. The size of the door opening should be designed according to the building design. The area of ​​the door gap should be (?) - Door perimeter, m;
