Cooling Load Calculator

AC cooling capacity and required air flow by floor area

100.01,076 ft²
m²/TR
Quick:

m² of floor cooled by 1 ton of refrigeration. Lower = denser load.

Btu/hr per CFM

Btu/hr produced per 1 CFM of supply air, averaged from manufacturer catalogs.

Formula. TR = (Area × kfactor) ÷ (m²/TR);  Btu/hr = TR × 12 000;  CFM = Btu/hr ÷ k;  m³/h = CFM × 1.699.

Find specific load

secondary tool

From a known capacity or air flow and the floor area above, get the implied specific load (m²/TR).

VixeldorfEstimates for early sizing. The specific-load values (m²/TR) reflect hot-climate practice (Israel, Middle East) and depend strongly on glazing, occupancy and insulation. Verify against a detailed heat-gain calculation and manufacturer catalog data before ordering equipment.
