WebAC Capacity = 600 sq ft * 0.0016 tons/sq ft = 1 Ton. In general, for every 600 sq ft, you need 1 ton of AC. This is a general estimate. You can use the ‘tonnage per square foot’ formula to calculate how many tons of AC you need. Here is the formula: AC Capacity (Tonnage) = (INSERT AREA IN SQ FT) * 0.0016 tons/sq ft WebJun 19, 2024 · Entering Air: 95°F. Desired Leaving Air: 55°F. Cooling Fluid: 45°F Water with a 10°F temperature rise through the heat exchanger. When we calculate the cooling load over a range of 0 to 100% humidity, here are the results: Note that when the relative humidity (RH) is 30% or greater, a portion of the cooling capacity is in the latent load.
