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.

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.

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

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

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.

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

Boiler Room Overview
![Page 10: For Cardinal Newman Hall Randall Lessard ET 493-01 Fall 2013 Dr. Cris Koutsougeras Advisors: Dr. Rana Mitra Mr. Byron Patterson.](https://reader036.fdocuments.us/reader036/viewer/2022062321/56649e235503460f94b11192/html5/thumbnails/10.jpg)
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.

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