TECHNICAL GUIDELINES. MEDIUM-HIGH TEMPERATURE REFRIGERANT (R-12 TYPE) air conditioning systems. The pressure and system capacity match R-12 in 40°F to 50°F evaporators, and the discharge pressure in hot condensers is only 5 to 10 psi higher than R-12 (a benefit in automotive AC and warmer r.
Pressure/Temperature Chart. Johnstone Supply is a leading wholesale distributor for HVACR equipment, parts and supplies available and in-stock at local branches.
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.
This is a pressure-temperature chart that specifies the saturation pressure for R410A at any given temperature. The R410A PT chart can be used to answer questions like: What are normal operating pressures for 410A? What is the pressure of r410a at 72 degrees Fahrenheit? What should gauge read for 410A?
The pressure-temperature (PT) chart is a valuable tool that service technicians use to check proper system operation. 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 ...

R134A PT chart is a standard table. Basically, this 134A PT chart tells you what is the pressure of R134A refrigerant at certain temperatures. The charts start at the low end (-49°F) and tell you the pressures all the way to the high end (150°F).
Discover the pivotal role of Refrigerant PT Charts in HVAC systems. Dive into our comprehensive guide to understand how these charts enhance system performance, troubleshooting, and energy efficiency in the world of cooling.
