Progress and Accomplishments Lessons Learned: – CFD validation is not a straightforward problem; especially with a dynamic system coupled with nonlinear boundary condition – CO2 system components are not readily available, e.g. low cost compressors at desired capacity Accomplishments: – Development of validated CFD model – Fabrication and validation of optimized wrap-around gas cooler design – Achieving EF of 2.1 with prototype CO2 HPWH based on low cost components (single speed compressor, single XV, wrap-around gas cooler) – Achieved projected installed price premium <$750 Market Impact: – We have demonstrated a more affordable path to ENERGY STAR-rated CO2 HPWH (low GWP – no direct environmental impact) – Sentech/SRA market assessment showed an estimated 72,000 – 180,000 total unit shipments five years following commercial viability to account for 0.037 Quads in annual national primary energy savings Awards/Recognition: – Noneyet 13
