Part 3: Quantified Results – 15-20% Energy Reduction, 1-2 Year Payback

The value of optimization must ultimately be validated by data. Through CFD simulation and bench testing, we documented key parameter improvements:

• Nozzle average velocity ↑ 18%-50% → enhanced debris pickup capability
• Impeller inlet velocity fluctuation controlled to <5% → reduced inlet impact loss

• Nozzle negative pressure ↑ 10%-15% → improved dust collection
• Total system pressure drop ↓ 15%-20% → lower energy for same airflow

• Vorticity significantly reduced → eddy losses ↓ 5%-8%
• Turbulence intensity ↓ 30%-50% → smoother airflow
• Noise level ↓ 8-10dB → meets nighttime operation requirements

• Fan aerodynamic efficiency ↑ 15%+
• Vehicle energy consumption ↓ 15%-20% – exceeding the target
• Suction nozzle negative pressure ↑ 10%-15% – improved cleaning rate
• Payback period: 1-2 years (depending on usage frequency and energy costs)
