R12 Refrigerant Ph Chart Pdf

The R12 PH chart becomes your . Without it, you’re just guessing on superheat and subcooling targets.

Compression is ideally isentropic (constant entropy). Follow the constant entropy line from Point 1 up to the condenser pressure. For 100°F condensation, the pressure on the R12 Refrigerant Ph Chart Pdf is approximately 138.8 psia. Where the entropy line meets this pressure is Point 2 (discharge to condenser).
