Pressure Temperature Chart - National Refrigerants, Inc.
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.
pt higher in R-22 content. This blend has higher capacity at lower temperatures (matches R-12 around -30°F), and also provides a closer match to R-500 at air.
How to Use a Refrigerant PT Chart for Accurate HVAC …
Dec 18, 2024 · Refrigerant PT charts, also known as Pressure-Temperature charts, are graphical representations that display the relationship between the pressure and temperature of a particular refrigerant at a given saturation point.
Refrigerant Pressure Temperature Chart [PT Refrigeration Table]
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.
PT charts are most often used for three purposes: to set a coil pressure so that the refrigerant produces the desired temperature; to check the amount of superheat above the saturated vapor condition at the outlet of the evaporator
How to read a pressure temperature chart for super-heat and sub …
Nov 15, 2024 · PT charts are most often used for three purposes: to set a coil pressure so that the refrigerant produces the desired temperature, to check the amount of superheat above the saturated vapor condition at the outlet of the evaporator and to check the amount of subcooling below the saturated liquid condition at the end of the condenser.
