HVAC Airflow Calculator

HVAC Airflow Calculator

HVAC App to Calculate Airflow

Our Pressure Temperature Chart for the selected refrigerant is available for quick access; just use the button labeled (P/T).

Use the refrigerant drop down for access to over 100 refrigerants.

Plus and minus buttons add and subtract values in intervals of 1 to their related input fields.

Overall Process:

  1. Enter refrigerant, temps, and pressures
  2. The math is done for you; superheat calculations, subcooling calculations, and airflow calculations all display Target, Actual, and Difference
  3. Repeat steps 1-2 until all HVAC Diagnostics check out as "Okay"; send system status report VIA text message or email as needed
  4. Sync customer units and customer diagnostics to the cloud with FLEETGRID

Measurements

Includes both Imperial (IP) and Metric (SI).

  • Temperature: Fahrenheit (°F), Celsius (°C), Kelvin (K), Rankine (°R)
  • Pressure: Pounds per square inch (psi), Kilopascal (kPa), Bar (bar), Torr (torr)
