team present: Kevin Hawkins, Skyler Olsen, Matthew White
topics discussed:
- A lack of requirements and what exactly to do about the problem dominated the meeting. We discussed possible avenues to take. A mathematical model depicting the feasibility of thermoelectric units versus vapor-compression systems will be created. This model will evaluate three basic sizes of refrigerator: small (1-3 cu.ft.), medium (3-8 cu.ft.) and large (8-14 cu.ft.). These three basic sizes will give the team three different options to investigate while we wait for further requirements from Dr. Jason West.
- Insulation was the next topic discussed. Through Kevin's and Skyler's preliminary research, we have some basic ideas about how refrigerators are insulated. Polyurethane seems to be popular in high-efficiency refrigerators and freezers. Reflective "blankets" could also prove to be effective. More information needs to be retrieved before any solutions can be reached.
- Matthew's experience in electronic control systems was next on the list. He has much experience with control systems and he is fluent in programming language and FPGA's. This comes as a welcome surprise and is exactly what the team needs! We discussed possible methods of control including temperature monitoring devices (infrared, thermistor) and methods to use the data. Sensitivity was a topic discussed and it was agreed upon that a sensitive and accurate controller is needed to maximize efficiency.
- The requirements document (Due Friday Oct. 2) as well as the timesheets were discussed and those requirements will be created and turned in by Skyler.
NOTE: We discussed in the meeting that Skyler needed the timesheets by Friday. This is incorrect. You need to send the timesheets by 7 PM Thursday to allow ample time for Dr. Kelly to sign off on them. Thanks.
