Calculate total air delivery CFM and outdoor fresh air intake from room dimensions and ACH guidelines for offices, cleanrooms, and clinics in Pune.
Technical Engineering Guide & Field Diagnostic Practices
Air Changes per Hour (ACH) dictates how many times total indoor air volume is circulated and filtered within 60 minutes. Controlled air changes remove airborne bio-effluents, volatile organic compounds (VOCs), and metabolic carbon dioxide. This calculator sizes supply CFM and fresh outdoor air intake in compliance with NBC 2016 and ASHRAE 62.1 standards, calculating the additional thermal sensible tonnage required to condition fresh outdoor ventilation air.
