Sizing & ROI Calculation Basis
Airflow Baseline: Required CFM is computed using ASHRAE industrial ventilation standards:
CFM = (Volume × ACH) / 60, with metric conversion CMH = CFM × 1.699.
Refrigeration Baseline: Central AC load is modeled at 300 sq.ft per Ton of Refrigeration (TR) in non-insulated industrial spaces with 1.25 kW/TR specific energy consumption.
Valutech Performance: One standard 18,000 CMH evaporative unit consumes 1.1 kW and effectively covers ~1,000–1,500 sq.ft with 100% positive-pressure fresh air.
Turnkey Payback: Estimated turnkey capital expenditure includes duct fabrication, supports, diffusers, plumbing, and electrical commissioning based on Bangalore works rates.
