Pressure values are displayed for R-22, R-410a, R-407c, R-134a and R-404a refrigerants.
Temperature and pressure diagram for constant boiling refrigerants - imperial and SI units. Search Search is the most efficient way to navigate the Engineering ToolBox.
In stationary refrigeration systems running in high ambient temperatures the use of an automotive blend can relieve problems associated with high discharge pressures, however capacity will suffer compared to R-12, especially as evaporator temperatures get lower. MEDIUM-HIGH TEMPERATURE REFRIGERANT (R-12 TYPE) TECHNICAL GUIDELINES
Traditional PT charts list the saturated refrigerant pressure, in psig, with a column for temperature down the left side. Single-component refrigerants and azeotropes boil and condense at one temperature for a given pressure.
Refrigerant Pressure Temperature Chart | HVAC Refrigeration - This page offers a temperature-pressure relationship chart for use in working with HVAC Systems that use R-410A, R-22, and R-134A. Additional refrigeration information and resources are located below the chart.

Pressure Temperature Chart USA (°F/psig) • Working with all refrigerants involves a degree of risk. It is recommended to use best practices and always adhere to safety protocols before and during when working with refrigerants. • DO NOT MIX REFRIGERANTS
To properly use it, you need an R410A PT chart (we also provide you with a printable PDF R410A PT chart at the end of the article). This is a pressure-temperature chart that specifies the saturation pressure for R410A at any given temperature.

For a single-component or azeotropic refrigerant, the operating pressure for the low side of a system can be found by cross referencing the desired coil temperature on the PT chart. For high-glide blends, however, the desired coil temperature is the average (or midpoint) temperature of the coil.
