Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Two prototype designs have been agreed upon for testing and sponsor has approved both.
Possible alternative components have been found to lower production costs
mounting methods and mister/fan casing redesin are still needed
Accomplishments from Previous Week
Mistcooling 10/24 MC610 fog nozzle has been identified as a possibly cheaper alternative to current metal nozzle.
Met with Steve Roberts to discuss implementation of filtering in future misting systems
Two self-contained designs have been selected for testing
CADing has begun for both designs
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Ordering of a sample of 4 MC610 mister heads for testing (Oscar)
Figure out an adjustable mounting system (Chota)
Test misters and how much water they use per hour (Cristobal & Erasmo)
Buy PVC piping/metal to make first prototype (Entire Team)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
New designs seem good, but we should keep in mind that high pressure water coming into tanks has caused ruptures in the past to his systems.
Air must escape the tank without water spilling out, or foreign water being forced in
While redesigning the fan casing, consider that the current model traps water behind the mister nozzle due to the design of the aluminium socket that it fits into, and this is inefficient.
Roto-molding allows for the creation of unique shapes, so our tank can be expanded to increase the volume (above from 4-8-17 meeting)
These are all comments to be considered as we move forward with our design
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Use metric units instead of empirical (4-5-17)
flow rates and pressures have been converted while analyzing components to test
80psi (550kPa) seems like a lot for a mister head to use. This is an area to optimize. (4-5-17)
After researching mister nozzles, it was found that many commercially available mister heads can support up to 1000psi (6e3kPa), and testing will be done to determine an optimal pressure to feed into the misters.
The number of batteries should not matter if the total voltage provided is 48V on average for each cart (4-5-17)
voltage converters have been delivered to the team from our sponsor for testing, and he has confirmed that 48V is the most common voltage on golf carts
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
We need a better looking presentation (background was bland)
Risks and Areas of Concern
Need to figure out a way to have adjustable bar/mount for the prototype
Will talk to Tom/Ian to find the right approach for this problem
Shipping for the mister nozzle will either take a week or cost more than the misters themselves
Resources or Information Required but not Available
Bill of Materials (still has not been sent to team)
SolidWorks files of current fan design
Schedule
Finding the best mister for the job
Testing required!
