Temperature and pressure diagram for constant boiling refrigerants - imperial and SI units. Search Search is the most efficient way to navigate the Engineering ToolBox.
Refrigerant Pressure - Temperature Chart. Pressure values are displayed for R-22, R-410a, R-407c, R-134a and R-404a refrigerants. Items Displayed in Red shows pressure in inches of Mercury. Items Displayed in Black shows pressure in pounds per inch gauge. Data points are reproduced based on available information.
Refrigerant Pressure Temperature Chart - PT Chart for R-410A, R-134A, and R-22. These are currently the three most widely used refrigerants on the market today for HVAC applications in residential and commercial use.
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.
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
Reading a refrigerant pressure-enthalpy (P-H) chart allows you to analyze and understand the thermodynamic properties of a refrigerant at different pressures and temperatures. Being able to read a refrigerant chart allows you check the health of a refrigerant system.
TEMPERATURE - PRESSURE CHART FOR R-22, R-410A, R-407C, R-134A & R-404A REFRIGERANTS FYI #289 9/17/2009. updated 10/10/2012. Data points are reproduced based on available information.
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
Saturation Pressure-Temperature Data for R410A (psig)*. Temp (°F) Pressure.
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.
