This study compares and analyzes the discharge status of smoke according to the method of installing a mobile blower in the event of a fire in an underground parking lot of an apartment using an evacuation simulation. An evacuation simulation was conducted on the situation in which the discharge of smoke in the event of a fire was discharged using a mobile blower to extinguish the smoke in the event of a fire by focusing on the part without smoke facilities in the underground parking lot. The results derived through experiments on the amount of smoke discharged using the natural exhaust method and the mobile blower in the underground parking lot are as follows. (1) In the event of a fire in an underground parking lot, the PPV (positive pressure ventilation) method, which has been mainly used in the field, should be used in a limited way. It can be an effective method if the exhaust port corresponding to the amount of the blower and the smoke exhaust is located nearby, or if the capacity of the apartment ventilation fan is designed to meet the 18CMH/㎡ of the National Fire Protection Association (NFPA) 88A or the 27CMH/㎡ standard standard for performance-oriented design evaluation and operation such as fire fighting facilities of the National Fire Protection Association (NFPA) 88A. (2) In the case of the additional mixing method (PPV+NPV) performed in the FDS experiment, smoke emissions increased by 5.1% compared to the NPV single method, and increased by 24.4% compared to the PPV single method.
