Data Center Cooling Airflow Capacity Calculator

Estimate sensible heat removal from airflow and supply-to-return air temperature difference.

Inputs

Planning inputs

Range: 1–10,000,000 CFM

Enter the actual or design airflow in cubic feet per minute. The 1.08 factor assumes standard air density and heat capacity.

Range: 0.1–100 °F

Enter return-air temperature minus supply-air temperature in °F. This is a sensible-only temperature rise; it does not include latent load.

Result

Sensible cooling capacity (Btu/h)
162,000
Sensible cooling capacity (kW)
47.48
Sensible cooling capacity (refrigeration tons)
13.50
