  3. Project 1: Using Wasted Heating for Heating Needs Daniel Crossen

  4. Current System 65-90°F 70-95°F Semi-warm water leaving pumps/entering cooling towers at 70-95° F and leaving cooling towers/entering pumps (for cooling) at 65-90°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.

  5. Current System (cont’d) 65-90°F 70-95°F 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.

  6. System Overview: Using Waste Heat for Heating Take the output of this system (65-90°F) 65-90°F 65-90°F 70-95°F 70-95°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

  19. Customer Feedback • Presented Design to Customer • Customer thought it would be a great idea for savings, but probably impractical unless the savings were immense. • Requires 400+ feet of piping 1-1/4” Lines • Also would require stronger pumps for underslab system. • Not really in the scope of MSD I or II • Perhaps MSD VIII

  29. Customer Feedback • Customer would like to find purpose for meltwater • Using “Heat Pipes” with a pre charged coil that will migrate depending on the delta-V between cold & hot side. • Is interested in the future possibility of using snow during the winter as well.
