Airflow Sensible Cooling Load
Estimate sensible cooling capacity from air volume flow, air density, specific heat, and temperature difference.
💡 Engineering Knowledge PrimerSensible air-side cooling load is the mass flow multiplied by air specific heat and dry-bulb temperature difference. Latent load, infiltration, solar gains, envelope gains, occupancy, and equipment heat are outside this first-pass screen.
OPERATING LIMITS — Sensible-only cooling calculation; add latent, envelope, infiltration, solar, occupancy, equipment, and psychrometric loads before HVAC selection.

Technical Methodology & Engineering Principles
GOVERNING EQUATION
SI: Q (kW) = [Airflow (m³/h) / 3600] × ρ × Cp × ΔT
US: Q (Btu/h) = CFM × ρ (lb/ft³) × Cp (Btu/lb·°F) × ΔT × 60
Assumptions & Scope
Sensible-only steady flow; constant air properties; no latent, envelope, infiltration, radiation, or equipment-load terms.
Operating Range & Boundary
Airflow, density, temperature difference, and specific heat must be positive.
