乘客电梯轿内通风的分析和研究

以载重量为1000kg的轿厢为例，考虑轿厢完全密闭、单个风扇工作及轿厢自然通风3种工况，对轿厢关人时乘客的呼吸安全性进行了分析。指出只要轿厢能够保证正常通风，则轿内乘客的呼吸是安全的；如果轿厢完全密闭，则在约1h内乘客的呼吸是安全的。据此，对电梯标准的修订及政府监管提出了建议。

Research on the Car Ventilation for Passenger Lifts

Regarding to passenger feedback on uncomfortable feeling when they are trapped in the elevator＇s car, 1000kg elevator car that is normally used in market has been taken as example for analysis. According to requirement on car ventilation by national standard, three conditions are considered, including the car closed tightly, one fan working and nature ventilation in car. For all those conditions, passenger＇s breath safety is analyzed under the condition of the passenger in the car being trapped, and it is pointed out that if car can ventilates normally, inear passengers are safe for breath. If car is closed tightly, then passenger can breathe well only in an hour. Based on above analysis, some suggestion for standard revision and government management are put forward here.
