Create a summary of the relevant standards you’re referencing to create a design for these systems. Be sure to continue to update as you find more standards! Also include other best practices you’ve found for working with your system, either on our own website, or from other literature.
Common HYPER lab standards:
CGA S1.3 – Pressure relief
ASME BPVC – Pressure Vessels
ASME Pressure Piping code
NFPA 2: Hydrogen fire code
Common HYPER lab best practices:
Complete a second house of quality or paradigm rating chart. In this house of quality, you will rank the design paradigms you came up with in regards to the engineering characteristic weights you got from the first house of quality. You should use the side section in the house of quality to ensure the literature you have found has been filled out to encompass all of the engineering problems you will be facing. See the Leachman’s poster on the topic for more information on how to use the house of quality as a literature search tool. As you find gaps, continue to fill out the standards section above. When finished, you should have selected a winning design concept and be ready to start design.
Start your design with simple sketches, and build into a full P&ID diagram, or diagrams of the system you hope to build. This is your place to showcase the full system design. Try to show all processes and connections. This will be a diagram that will likely be under constant improvement as the system is tweaked, new features are added, and you gain a better understanding of the system you’re building. Make sure to keep the site up to date with changes!
Use this section to show case the design calculations you have made. It is not necessary to write out all calculations, but briefly summarize the assumptions you made, how the calculation was performed and the conclusions. If you coded it in EES, note the location of the file saved on HYPERDRIVE for future reference. This section is what you can point to later when questions come up about how you sized something, whether you’re sure you meet a code or standard, or how you know how the system will operate. It will also let future users of the system look back on your design decisions and understand how and why they were made.
This section is for detailed safety analysis. List general safety requirements for running the system. Then go through a safety hazards and failure modes analysis with at least one other person from the lab. State hazard / failure modes, potential risk, causes, mitigation strategies, and suggested responses. Ensure that all safety measures are up to relevant standards (as you should have listed above).
General Safety Requirements:
- Limit the amount of hydrogen in the room to no more than one K size bottle.
- Keep wiring, tubing, and cords as clean as possible.
- Always ground all electrical equipment and all conductive tubing/pressure vessels to prevent electrical discharge.
- Always purge systems at least twice before allowing hydrogen into the system.
- Always leak check the system before operation.
Always discharge static buildup of personnel before touching the system
