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)
5. Heat Exchanger Test

  • Test Performed using the Storage Tank

Cooling Test Setup

  • Test Performed using the Secondary storage tank (250 gallon tank)

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
