Presentation on the results of our built solar heating and cooling system for our house. Presentation highlight testing methods and results.

1. Solar Heating with Cooling Elliott Layus Ben Ly Lily Duncan

2. Problem: Testing the residential heating and cooling system our team designed.

3. Testing: Setup and Procedure

4. Solar Panel Test Setup Test Performed using the primary tank storage (50 gallon tank)

6. Piping Thermal Wells

7. Other Testing Flow-Tests Domestic Hot Water Hose Solar Panels Cooling Tower

8. Test Results

9. Results: Solar Response

10. Domestic Hot Water Heat Rate: Cost of Natural Gas: $.995/Therm Cost Savings of Test: .04869 Gallons Used in Test: 22.5

11. Domestic Hot Water Savings per gallon .00322 Weekly Estimated Usage Showers =472.5 Laundry =160 Dishes =20 Sink =75 727.5 Weekly Savings $2.34/Week $121.70/yr

12. Solar Space Heating Delivers: 100 MJ/dayCosts: 14.08 MJ/dayCOP: 7.10

13. Total Gains from Useful Heat

14. Cooling Tower A tank response test was performed for 1 hour The tank was cooled by 2.5 K (275 gal.) 11.12 Mj of energy was rejected A standard efficiency A/C unit would provide 2.85 MJ Actual savings depends on conditions of surrounding and usage pattern

15. Cooling cycle: Storage Tank Response

16. Cost Breakdown Savings per Year: $428 7 year payback
