R32 · R410A · R290Refrigeration Performance Analyser
Convert measured gauge pressures to saturation temperatures using your PT engine, then calculate superheat and subcooling from pipe temperatures. Use the result as evidence alongside airflow, load and control state — not as a stand-alone charge diagnosis.

1 · SuctionCompressorLow-pressure vapour enters compressor.
2 · High sideCondenserHeat rejected and refrigerant condenses.
3 · MeteringEEVPressure is reduced and feed is controlled.
4 · Low sideEvaporatorHeat absorbed before returning to suction.

Interpretation limits. Inverter systems continuously alter compressor speed and electronic expansion-valve position. Superheat/subcooling targets are model- and operating-condition dependent. Confirm airflow, load, fan operation and exact manufacturer data before making a charge decision.
