Enhanced Low Pressure Drop Acoustic Suppressor Nozzle for Inert Gas Discharge Systems

This inventive concept discloses improved acoustic suppressor nozzles for inert gas discharge systems, featuring strategically placed sound dampening materials and pressure reducing devices to minimize pressure drop, reduce sound power levels, and optimize inert gas flow.

Inert gas fire suppression systems are often used to protect sensitive equipment. The original patent disclosed a low pressure drop acoustic suppressor nozzle, but it had limitations in terms of sound power levels and pressure drop. This inventive concept addresses these limitations by introducing novel features that reduce sound power levels and pressure drop, resulting in a more efficient and effective system.

The enhanced nozzle features a sound dampening material strategically disposed within the nozzle to reduce sound power levels to no more than 120 dB for a frequency range from 500 to 10,000 Hz. Additionally, a pressure reducing device is mounted remotely from the main nozzle to minimize pressure drop. The nozzle can be designed to operate at a pressure ratio of at least 1.5:1 between the inlet and outlet pressures, resulting in a reduced pressure drop and improved system efficiency. A method for optimizing inert gas flow in a fire suppression system is also disclosed, which involves determining the required inert gas flow rate, selecting a nozzle with a pressure drop no more than 70 psi higher than the enclosure gage pressure, and configuring the nozzle to achieve the required flow rate while maintaining a sound power level of no more than 125 dB. A fire suppression system with multiple nozzles, each having a pressure drop no more than 80 psi higher than the enclosure gage pressure, and a control system that dynamically adjusts the flow rate of each nozzle to maintain a uniform inert gas concentration within the enclosure, is also disclosed.

The new inventive concept's novelty lies in the strategic placement of sound dampening materials and pressure reducing devices, which reduces sound power levels and pressure drop, making the system more efficient and effective. The inventive step is the combination of these features, which provides a significant improvement over the original patent.

Alternative embodiments may include using different types of sound dampening materials, varying the placement and design of the pressure reducing devices, or incorporating additional features to further optimize inert gas flow. Variations of the inventive concept could be applied to different types of fire suppression systems or inert gas discharge systems.

The enhanced low pressure drop acoustic suppressor nozzle has significant commercial potential in the fire protection industry, particularly in applications where sensitive equipment needs to be protected. The inventive concept's ability to reduce sound power levels and pressure drop makes it an attractive solution for industries such as data centers, museums, and healthcare facilities.
