Fluid Systems Mechanical Design
Budget: $250 – $750 USD
Engineering Brief
Engineering Design calculations a Direct Low Pressure (DLP) fire suppression system similar to common ones found in the marketplace according to the following standards
Propose a solution of a Direct Low Pressure (DLP) fire suppression system that meets the following standards and detailed engineering design and report.
UL 2166: UL Standard for Safety Halocarbon Clean Agent Extinguishing System Units
ISO 14520-1:2015: Gaseous fire-extinguishing systems Physical properties and system design
NFPA 2001 Standard on Clean Agent Fire Extinguishing Systems
The system should be scaled for 3 systems 1.5 Kg System, 2.5Kg, 5Kg system
See the attached document on how the system works and references to other products in the marketplace.
Main functions
Detection and suppression using a pneumatic heat detection tube.
Ability to charge the cylinder to pressurize it
Ability to charge the Heat Detection Tube
The manifold should be able to equalize the pressure in the tube and cylinder
Prevent the system from leaking pressure once it’s pressurized
Ability to connect a low-pressure switch
Ability to deactivate the system by de-pressurizing without discharging the suppression agent.
The system should have a way to relieve pressure either through a pressure relief valve or a built-in relief valve on the manifold
The system should be able to release a suppression agent through the heat detection tube once.
Ability to isolate the detection tube from the system, like maybe using a ball valve.
Deliverables
Provide design calculations and simulate a Direct Low Pressure (DLP) Fire Suppression System
What is the volume of the Novec 1230 agent that should be used for the 1.5 Kg System, 2.5Kg, 5Kg system
How long should the detection tube be before it is no longer effective
How many cabinets can be protected by each system;1.5 Kg System, 2.5Kg, 5Kg system
How big of a volume per cabinet can be protected by each system; 1.5 Kg System, 2.5Kg, 5Kg system
Explain the influence of the pressure on the suppression
What happens if we pressurize the system at 4 bar instead of 12 bar or 15 bar
How does the pressure push out the suppression agent to the tube, what is the driving force?
Explain the influence of the inert gas used to charge the cylinder and the tube kit
What happens if we charge using air?
What happens if we use other inert gases other than Nitrogen
Explain what class of fires can be protected with the system and provide calculations and literature to support
