The invention discloses an elevator hoistway ventilation control system which comprises hoistway ventilation holes formed in the upper end of an elevator hoistway, first electric control opening and closing devices which are installed on the hoistway ventilation holes and used for opening and closing the hoistway ventilation holes, and an elevator main control system which is connected with the first electric control opening and closing devices and is suitable for opening and closing the hoistway ventilation holes by controlling the first electric control opening and closing device. When an elevator car is in the stopping deceleration state and decelerated to the preset speed or is close to the preset speed, the elevator main control system controls the first electric control opening and closing devices to close the hoistway ventilation holes so as to eliminate the chimney effect of the elevator hoistway; and when the elevator car is in the starting acceleration state and is accelerated to the preset speed or is close to the preset speed, the elevator main control system opens the hoistway ventilation holes by controlling the first electric control opening and closing devices so asto eliminate the piston effect of the elevator hoistway. Therefore, through the elevator hoistway ventilation control system, adverse influence of the piston effect and the chimney effect of the elevator hoistway can be reduced, and the safety and comfort of an elevator are improved.

    本发明公开一种电梯井道通风控制系统,包括:井道通风孔,形成在电梯井道的上端;第一电控开合装置,安装在井道通风孔上,用于打开和关闭井道通风孔;和电梯主控制系统,与第一电控开合装置连接,适于通过控制第一电控开合装置来打开和关闭井道通风孔。当电梯轿厢处于至停减速状态并且已减速到预定速度或接近预定速度时,电梯主控制系统通过控制第一电控开合装置关闭井道通风孔,以消除电梯井道的烟筒效应;当电梯轿厢处于启动加速状态并且已加速到预定速度或接近预定速度时,电梯主控制系统通过控制第一电控开合装置打开井道通风孔,以消除电梯井道的活塞效应。因此,本发明能减小电梯井道的活塞效应和烟筒效应的不良影响,提高了电梯的安全性和舒适性。
