HVAC Refrigerant PT™ is the pressure-temperature reference built for air conditioning and refrigeration professionals. Look up P/T charts and physical properties for 55 refrigerants in seconds — completely offline, so every value is ready on the job site with or without a signal.
WHAT'S INSIDE
• P/T charts for 55 refrigerants, with bubble and dew pressures on the same line
• Values interpolated to every whole degree — read the exact number instead of estimating between rows
• Superheat, subcooling and saturation calculators for charging fixed-orifice and TXV systems
• Full physical-property sheet for every refrigerant
• Seven pressure units and °F / °C, switchable in one tap
• Redesigned, tabbed interface — built for phones and tablets
• 100% offline. No account, no ads.
PRESSURE / TEMPERATURE CHARTS
Bubble and dew pressures are shown together for each temperature and interpolated to the whole degree for precise readings. A quick-scroll slider moves you through the chart fast.
CALCULATORS
Enter your field readings to get target superheat and subcooling, plus saturation temperature — the numbers you need to charge a system correctly.
PHYSICAL PROPERTIES
For each refrigerant: classification, safety rating, critical temperature and pressure, density, specific heat, ozone depletion potential, global warming potential, typical applications, and recommended lubricant.
PRESSURE UNITS
• psig – pounds per square inch, gauge (relative to atmospheric)
• kPa – kilopascal
• psia – pounds per square inch, absolute (relative to vacuum)
• inHg – inches of mercury
• atm – standard atmosphere
• bara – bar, absolute (relative to vacuum)
• barg – bar, gauge (relative to atmospheric)
