1. For Cardinal Newman Hall Randall Lessard ET 493-01 Fall 2013 Dr. Cris Koutsougeras Advisors: Dr. Rana Mitra Mr. Byron Patterson

2. Overall Objective  The goal of this project is to design and install 2 independent solar thermal systems that will tie into the existing boiler water heating system and domestic hot water system, therefore reducing the energy consumed and providing a cost-effective solution to obtaining heated water for Cardinal Newman Hall.

3. Solar Thermal System  Solar collector absorber plates harness solar radiation and convert it to thermal energy.  Thermal energy is transferred to a heat- transporting fluid flowing through the collector.

4. Heat Exchange  This fluid, and water from a return line meet in a heat exchanger, and thermal energy is transferred to the water.

5. Pump  The heated water is pumped back to a boiler to be “heated”.  A sensor determines if the heated water is needed.

6. Boiler  If enough heated water is already in the boiler it will be able to maintain it’s minimum temperature.  This heated water keeps circulating until the boiler needs it.

7. Results  This process effectively keeps the boiler from turning on, saving nonrenewable energy, while maintaining hot water in the system to supply the building.

9. Boiler Room Overview

10. Solar Collector Location  Most efficient and effective location for the collectors would be on the roof.  Mounted to I-beams spanning across the ceiling of the boiler room for strong structural support.  Air vent above boiler may complicate mounting location.

11. Schuco CTE 520 CH  Very efficient collectors Rated thermal output of 2.0 kW  Dimensions (L x W x H) 84.72” x 49.29” x 3.66”  Capable of fitting 4 in an array on the roof of boiler room.

12. Pumping Stations Preferred location of pumping stations

13. Measurements PUMPS Heating Water Pump Domestic Hot Water Pump Inlet Pipe Size (in) 1 ¾2 Outlet Pipe Size (in) 11 ½ BOILERS Boiler (Thermo Pak) Domestic Boiler (Copperglas) Input (btu/hr)1050400000 Working Pressure (psi)75125 Capacity (gal)120250 FuelNatural Gas

14. Calculation  Calculated volume flow rate to later determine how much thermal energy will be needed to keep the systems heated.

16. Accomplishments  Overall better understanding of solar thermal system  Applied learned methods to evaluate real-life problem

17. Future Work  Over the break and next semester I intend to: Finish all calculations to determine most efficient solar thermal systems for this application. Install solar thermal systems to maximize efficiency. Design a meter application to document the amount of energy produced by this application.
