Task Abstract: To come up with a new design for cold glycol to flow through a testing machine at Hamilton Sundstrand. |
Task Objectives: To design a new system that would satisfy pressure, temperature and design conditions with a material that is rarely used. |
Esssential Understandings/Questions:

Task Description: Through field trips and class visits as well as preparation in thermodynamics and fluid mechanics, the studetns iwll be able to come up with a design solution. The intent is to size and design a cold glycol system that will provide the test laboratories at Hamilton Sundstrand with minus 18 degree Fahrenheit glycol flowing in a closed loop system at 12 to 15 gallons per minute (gpm). The system will have a total cooling capacity of 16 tons. Note that this cooling capacity is rated at the operating temperature. The students may design a conventional chiller-based cooling system or consider using a liquid nitrogen cooled heat exchanger cooling system. The design must incorporate the following:
The students will provide a written report that will include:
