Subcooling Calculator
Calculate subcooling for HVAC systems to determine proper refrigerant charge. Input liquid line temperature and pressure to get accurate subcooling values.
Step 1: Temperature & Pressure
Understanding Subcooling
Subcooling is the difference between the actual liquid temperature and the saturation temperature at a given pressure. Proper subcooling ensures efficient system operation and prevents liquid floodback.
Step 2: System Parameters
About Subcooling Values
Typical subcooling ranges from 8-15°F for most systems. Too low indicates undercharge, too high indicates overcharge. Always refer to manufacturer specifications for exact values.

Subcooling Analysis
Subcooling Formula
Subcooling = Saturation Temperature – Liquid Line Temperature
To calculate subcooling: Find the saturation temperature from pressure using PT chart, then subtract the actual liquid line temperature. Positive values indicate proper subcooling.
