    Project Overview:
    The main ventilation fan’s no‑stop, reverse‑start system primarily involves adding a horizontal short‑circuit test damper to the existing ventilation system. This damper reduces the ventilation resistance during grid‑connected starting under the conventional shutdown‑to‑reverse‑start mode, thereby increasing the success rate of the main fan motor’s startup.

To enhance the success rate of switching between main ventilation fans and to prevent delays caused by sudden failures of the standby fan during the switchover, this project adopts a transition from cold standby to hot standby. Specifically, the standby fan is started while the operating main fan remains running; once the standby fan has started up normally, the switch is executed, thereby ensuring reliable hot standby. If the standby fan fails to start properly, the switchover can be temporarily suspended to first troubleshoot the fault and carry out equipment maintenance. Since the actual fan‑switching process has not yet commenced at this point, the normal operation of the original fan and the ventilation network remain unaffected, thus resolving the uncertainty surrounding whether the standby fan can reliably start under the conventional shutdown‑based switchover mode.

During the retrofit, normal operation of the fan is not affected, and a one‑button switch allows the fan reversal to be completed within 90 seconds.
