About RefCalc: Refrigerant PT Chart
RefCalc is the fast, offline Pressure–Temperature chart and Superheat/Subcooling calculator built for HVAC/R technicians — no subscription, no ads, one-time purchase.
CHECK CHARGE IN SECONDS
Enter suction pressure and suction line temperature to get instant superheat. Enter liquid line pressure and temperature to get instant subcooling. Color-coded results show at a glance whether you're in range.
FULL PT CHART, ANY REFRIGERANT
Type a pressure, get the saturation temperature. Type a temperature, get the saturation pressure. For blend refrigerants, RefCalc shows both bubble point and dew point plus the glide between them — the detail cheap PT apps get wrong.
BUILT-IN REFRIGERANTS
R-410A, R-32, R-454B, R-452B, R-22, R-134a, R-404A, R-407C, R-448A/R-449A, R-290, R-1234yf, R-513A — including the newer A2L mildly-flammable refrigerants (R-32, R-454B, R-452B) that older apps don't support.
WORKS YOUR WAY
• psi / bar / kPa / MPa
• Gauge (psig) or absolute (psia) reference
• °F or °C
• 7 languages: English, Spanish, Chinese, Portuguese, Japanese, Korean, Vietnamese
100% OFFLINE
No account, no internet permission, no analytics, no ads. Your data stays on your device. Buy once, use forever.
Refrigerant data sourced from NIST REFPROP and manufacturer/ASHRAE published PT charts. RefCalc provides the math — always confirm final charge against the equipment nameplate or OEM charging chart.
