Status at End of Fall
Heat Regulation for Refrigeration Unit:The heat bypass for the refrigerator to be automated and determined by refrigerator temperature
Water Heating Unit:Bypass water-heating unit and distiller to be added.
Alternative Fuel:A conversion kit to be added that will allow the engine to run off of compressed natural gas (CNG) and gasoline.
Gas Expansion:The expanding gas from the natural gas tank to be used to aid in cooling the current cool space.
Current Status
Design choices have been made
All component have been ordered except for the natural gas tank.
80% of the components have been received.
Preliminary expansion calculations from Brazilian teammates have been completed.
Design of second cool space.
Scope of Work for Spring: Heat Regulation
Tasks:Machine Valves, install Piping and Install Electronic Components for Automation.
Valve

Tasks:Install conversion kit and piping for natural gas supply
Obtain natural gas
Engine
Scope of Work for Spring: Expansion
Tasks:Route expanding gas to cool distiller collection container.
See Video
Scope of Work for Spring: Testing
• Temperature: K-type thermocouples
• Flow Velocity: Flow-meter
• Data Collection: LabVIEW

Collaboration with Brazil: Expansion
The team has accomplished the following via weekly video conferences, e-mails and file exchange:
– Preliminary calculations for cooling effects of rapidly expanding gas
– Design of second cool space around distiller collection unit.
Major Difficulties
• Electronic Components• CNG• Assembly• Scheduling
Schedule/Plan: Proposed Spring Schedule
Conclusion• Status at End of Fall – Design Choices Solidified• Current Status
– 80% of components in house ready to be assembled– Change to how expansion will be used
• Scope of Work for Spring– Assembling and modification to take place in January
and February– Testing to begin in March
• Collaboration with Brazil– Expansion will be used to cool water from distiller
• Schedule/Plan
