About the Cooling Calculators

Cooling calculators help HVAC engineers size and evaluate air conditioning and refrigeration equipment. This collection covers sensible and total cooling load estimates, SEER and EER efficiency conversions, evaporative cooling performance analysis, and DX coil capacity calculations. Use them during design to verify that proposed equipment can meet the cooling demand for a given space, or during commissioning to confirm that measured performance matches the design intent. Each calculator applies standard industry formulas so results are consistent with manufacturer ratings and energy code requirements. Whether you are selecting a rooftop unit, evaluating an evaporative pre-cooler, or comparing efficiency ratings across equipment options, these tools provide the quick answers engineers need on the job site or at the desk.
