Superheat vs Subcooling method for adding R22

1- run the condenser for 15 minutes
2- Read the liquid pressure at liquid line port at the condenser
3- Read temp at liquid line near the liquid line port.
4- Subtract the measured liquid line temp with saturation temperature ( R22 Pressure chart )

Liquid Line Pressure: 200PSIG
Saturation temp ( pressure chart ) : 100F
Liquid Line temp (probe): 90F

Subcooling = 100F - 90F = 10F

This is your real subcooling. You need to know target subcooling also
