Mission Statement • "The mission statement of this project is to develop several solutions to improve the campus at the Rochester Institute of Technology.
Project Summary • We were charged with reducing the carbon footprint of RIT’s hockey arena. • However, our project is slightly different than most other projects. • We were given resources, but not a pre-determined project • Common Theme: • “It would be nice if you could…”
Our Projects • 1. Reclaiming waste heat from the Hockey Arena Pumps. • 2. Using waste cooling to pre-treat air for air conditioning. • 3. Using the ice pile outside the hockey arena to pre-treat air for Air Conditioning. • 4. Using the ice pile outside the hockey arena to cool pipes in the pump coolant loop. • 5. Reducing the overall emissions of the hockey arena.
Current System Semi-warm water leaving pumps/entering cooling towers at 65-90° F and leaving cooling towers/entering pumps (for cooling) at 45-55°F Cold water leaving pumps/entering underslab (for warming of ground)at 36° F and leaving underslab/entering pumps at 32°F Currently, these two systems do not interact, other than through the pumps. However, the semi-warm water is only used to cool the pumps, and does not come into contact with the cold water at all.
Current System (cont’d) RIT pays to cool down this water from 65°-90°F to 45°-55°F while… …in the next room, we pay to heat up this water from 32° to 36°F They are on two separate loops, never coming into contact, and energy is wasted moving their temperatures in opposite directions.
System Overview: Using Waste Heat for Heating Take the output of this system (65-90°F) And take the output of this system (32 °F) And put them through a heat exchanger to utilize the waste heat/cold from one system to heat/cool the other system
The Ice Pile: Projects 3 & 4 • Currently, there is an ice pile outside of the Ritter Arena made from the zamboni’s resurfacing of the ice rink. • Our customer would like to use the ice for cooling of some system in the ice rink. • The customer referred to it as “The Most Expensive Ice in the World”, unless we were to use it to make one of these…
Customer Priority Evaluation • 5- Lower Energy Usage than Current a/c. • 5- 10 year maintenance interval • 5- Safe for operation • 5- Easily integrated • 5- Professional appearance • 4- Low prototyping cost • 4- Intuitive use • 3- Easy Filling • 2- 1-year payback • 2- Large ice capacity Rank (1-5) • The customer added this constraint : • The zamboni cannot travel off of the loading dock or turn outdoors.
Ice Pile for Pipe Cooling (continued) • Integrates with current cooling tower system • Low downtime when being integrated • Use at the same time with the cooling tower system
System Overview: Reducing Emissions of the Ice Arena • Zambonis, powered by gasoline, diesel, or propane, are the second major source of emissions in hockey arenas after CO2 emissions from the crowd • Ritter Ice Arena is equipped with four air handlers- three to ventilate the arena and one to dry the air • Currently, only CO2 is monitored, and the building is kept positively pressured to keep down levels of other emissions
Current Emissions Monitoring • Currently, CO2 levels are measured on one of the four air handlers in the arena • CO2 levels can get very high during games due to the number of spectators if ventilation is not increased • In the past, before installation of computer controls, the Zamboni driver could flick a switch where the vehicles are parked to increase the ventilation while running
