A study on cooling rate with blade and sound fire extinguisher

초록

Since the Industrial Revolution, human civilization has developed rapidly and the buildings have become skyscrapered and their interior has become very complicated. A new conflagration suppression method is needed to suppress or prevent conflagration in various environments due to the change of fire fighting environment. Sound Fire Extinguisher, which is actively studied at Sori Sound Engineering Research Institute (SSERI), is a new type of extinguishment facility that can be used for suppression and prevention of conflagration in various environments. Sound Fire Extinguisher uses acoustic lens to minimize the attenuation of sound energy and transfer energy to the target point. It can prevent conflagration by lowering ambient temperature even before conflagration. In this study, we experimented to see if the Sound Fire Extinguisher could prevent conflagration by lowering the ambient temperature. Experimental results show that when the Sound Fire Extinguisher sound component of the same wind speed is supplied, the heated tableware is cooled by 10 ~ 20% faster than the wind speed of 2m/s. These results show that the Sound Fire Extinguisher can be used to prevent conflagration, since the sound component of the Sound Fire Extinguisher itself promotes the surrounding thermal dissipation to cool quickly. © International Research Publication House.
