1. Solar Water Heating System
Progress Presentation
Meghan Hanington, Blake Meech, Alexander MacDonald,
Connor Hanna & Alex MacDonald

2. Review of Goals
Determine the current hot water consumption in MacIsaac Hall and identify available space in the mechanical room and on the roof of the building.
Determine the proper methods for integrating our solar water heating to the existing steam based heating system.
Decide on long-term or short-term hot water storage
Find the annual solar radiation in Antigonish
Contact local suppliers and continue to research financing options

3. Challenges
Meeting with Josh Bouchie was delayed because of conflicting schedules and reading week.
MacIsaac Hall mechanical room inspection was also delayed.
Meeting with Mohammad was limited due to the delay.

4. Meeting with Mohammad Azad
Thursday, February 15th
Recommended short-term hot water storage instead of long-term.
Thermodynamic calculations can be used to determine pump and storage tank capacity.

5. Meeting with Josh Bouchie & Kevin Latimer
Wednesday, February 28th
MacIsaac Hall tour (mechanical room and roof)
Design plans for two similar solar hot water projects
Available chimney space
Problems to be looked at further:
Glycol overheating
Drainback system vs heat release
Recirculation of hot water

10. Accomplishments MacIsaac Hall inspection
Short term hot water storage will be used
Available room for storage tanks in mechanical room
Available roof space is approximately 104m^2
Data collection for solar radiation on campus
Estimate of current hot water consumption and energy demand
Set parameters on system design

11. Moving Forward... Contact Thermo-Dynamics Ltd.
Pricing and specifications of products
Continue to research financing options for project
Second meeting with Mohammad and Josh
Engineering analysis
Heat transfer in collectors and storage tanks
Determine methods for connecting our SWH system to the recirculation piping
