 "The mission statement of this project is to develop several solutions to improve the campus at the Rochester Institute of Technology.

 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…”

 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.

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.

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.

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

 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…

 5- Lower Energy Usage than Current a/c.  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.

 Integrates with current cooling tower system  Low downtime when being integrated  Use at the same time with the cooling tower system

 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

 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
