Ventilation and ventilation control method of underground parking ventilation system that can switch between forward and reverse using sensor and have cooling function and backdraftdamper

摘要

The present invention relates to a ventilation and ventilation control method of an underground parking lot ventilation system capable of forward and reverse switching using a sensor and equipped with a cooling function and a reverse flow prevention damper, and more specifically, a forward and reverse rotation is possible, thereby increasing the ventilation effect. In addition, since it has its own cooling function, it relatively cools the space inside the underground parking lot without having a separate systemic air conditioner to suppress the temperature rise, and in particular, suppresses the heat island phenomenon caused by hot smoke in the event of a fire, thereby preventing safety accidents. The present invention relates to a ventilation and ventilation control method of a ventilation system in an underground parking lot with a cooling function and a reverse flow prevention damper that enables forward and reverse switching using an improved sensor to prevent and reduce personal injury.
