PROJECT OVERVIEW: Currently RIT consumes large amounts of energy, and 20% - 30% of the total energy usage is due to poor behavior. To scope down this, the focus of the project is the Ritter Ice Arena, which is one of the buildings that consume most of the energy on campus, and at the same time it can be considered a very inefficient building.

The Ice Arena consist on three different water loops; cold water to make the ice, warm loop to prevent freezing of the underslab, and warm loop to cool down the pumps (Cooling towers loop). The goal is to reduce the energy consumption in the Cooling Towers by reducing the temperature of the water in the loop by using the ice dumped by the Zamboni. To do so, a heat exchanger will be incorporated to the loop.

The following PRP will present the information gathered, and a brief analysis of it.

 Constraints: - Must determine an effective way to get the ice from Zamboni into the system. - During winter the system can be restricted due to the possibility of freezing. - The water table under the Ice Arena might limit the possibility of digging to implement the system. - Scaling the model to proof concept might encounter problems due to complexity of system. - Integrating proposed system to existing one can be challenging due to lack of space.

 Project Deliverables: - 3D scaled model - Temperature model for tested data - Temperature interface specifications and control system - Bill of materials - Estimate costs for large scale model

 Budget Estimate (Scale Model);

 Intellectual Property (IP) considerations:

As a federally funded project, any IP generated as a result of this project will belong to RIT

STUDENT STAFFING:

 Anticipated Staffing Levels by Discipline:

How Discipline Anticipated Skills Needed Many? EE 1: Design the temperature reading system and integrate to the project EE 1 working together with the CE 1. ME 1: Determine heat exchange rates between ice and water, water flow rates and the requirements the system needs do have to fulfill the specifications in water temperature. ME 2: Design the ice container and the heat exchanger, according to the ME 3 specifications working together with ME 1 to validate theoretical calculations. ME 3: Model the system using computer-based software. Collaborate with ME 1 and ME 2. Determine and acquire the components needed in the system. CE 1: Elaborate system that will command water flow according to the CE 1 temperature readings, and the water flow specifications determined by the team. Work together with the EE 1. ISE 1: Elaborate design according to the requirements so the design fits ISE 1 the designated space. Work on ergonomic and human factors for the system and focus on system integration.
