A study on cooling effect of sound components

초록

Although fire is a necessity for mankind, it is also a subject of fear for humans under the name conflagration. As the building is becoming taller and larger, the precautionary measure as well as the preparation of aggressive conflagration is needed. Sound fire extinguisher is an extinguishment facility suitable for a complicated fire fighting environment. Also, it is expected that it will provide a function to prevent conflagration by the cooling effect of sound component of sound fire extinguisher. In this study, we tried to measure the cooling effect of the sound component of the sound fire extinguisher through the cooling measurement experiment. As a result of the experiment of charpter3, it was confirmed that the cooling time is reduced by 27% on average when the sound is provided, compared with the case where no sound is provided. In addition, it was confirmed that the time required for cooling is significantly reduced when sound is provided in most temperature range of 100 ° C or less. The sound effect of sound fire extinguisher 's sound component is expected to provide a function to prevent conflagration by operating before conflagration in a fire fighting environment where accessibility is difficult or conflagration signs are difficult to identify. © International Research Publication House.
