Mechanical Engineering Technology

• Solar - Air/Photovoltaic Heating System
• Components
• Fabrication
• Testing

12
Solar Air System

• How the system works
• Heat collected in 4 X 8 solar air panel.
• Hot Air is blown onto the rocks by fan,
  circulated back through panel.
• When fan is reversed, heat is removed from rocks,
  blown into building, circulated through rock
  storage bin.
• Air movement controlled by backdraft-dampers.
• Whole system is powered by a PV System.

Project Wrap Up

• Building Re-Construction completed ONE MONTH
  AHEAD of schedule
• Heating System
• Independent from downtown power.
• Low cost.
• Low Maintenance.

25
Project Wrap Up (cont.)

• If needed, system is very easy to service.
• Less than 500.00 total system purchase costs.
• The Verdict SUCCESS!!
