Team 6B: Design of Solar Water Heater for a single family home Speakers: Nabila Sharieff (Project leader) Kodjo Quaye (Calculations lead) Rita Saad (CAD lead) George Mitri (Documents lead) Tuesday April 7, 2015 [1] Project Presentation:

Team Distribution Divided into four sub- groups: The research team: Looked into various SWH systems Types of collector tubes The calculations team: Estimated Load required Sized the piping system Calculated energy output from system The CAD team: Designed the SWH system Designed the elevation schematic George Mitri Team 6B The Research Team The Calculations Team The CAD Team The Document team

Documentation Ensure all material encompassed within the final report and presentation accurately convey the focus points of each subsystem in a organized and professional manner. Coordinated members Established constant line of communication Utilized a dynamic method of documentation Review/Compile Final Document George Mitri

Research: Types of systems Active vs. Passive: ●Passive: ➢ Heat-driven convection ➢ Low cost ●Active: ➢ Use of pumps ➢ Superior efficiency ➢ More control over system Nabila Sharieff [2]

Research: Types of systems cont. Direct vs. Indirect ●Direct or Open Loop ➢ Circulate water through collectors ➢ No freeze protection ●Indirect or Closed Loop. ➢ Use a Heat Transfer Fluid (HTF) : water and propylene glycol ➢ Offer freeze protection Nabila Sharieff Direct Indirect [3]

Research: Types of collectors Important parameters  Freeze tolerance, high efficiency in year round (System location: Windsor, ON) Flat plate collector ➢ Simple and maintenance free ➢ Not efficient in cold weather Evacuated tube collector ➢ Vacuum space in tube ➢ Greater efficiency in cold temperatures PV, simple absorber, etc. Nabila Sharieff Flat Plate Evacuated Tubes [4]

Calculation Flow Solar Calculations Load Calculations Service Water System Sizing Basic Solar Radiation Calculation to Collector Calculation Required Load/Estimated Load Service Water w/ and w/o storage Pipe, pump and boiler sizing Kodjo Quaye

Basic Solar Calculations Factors considered for Solar Calculations: Declination Solar and Sunset hour angle Extraterrestrial and Clearness Index Irradiance Sky Temperature Water Temperature Kodjo Quaye

Load Calculations Kodjo Quaye

Service Water With Storage Water serviced to the home with a storage system Consider; No. of evacuated tubes Storage Capacity Without Storage Water serviced to the home without a storage system Consider; No. of evacuated tubes Storage Capacity Kodjo Quaye

System Sizing Pipe Sizing – Closed pipe system Schedule 40 tubing Limit Friction losses to 3 ft of water per 100ft of pipe Limit Water velocity to 6fps (Figure A.4b) Pump Sizing Boiler Sizing Kodjo Quaye
