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.
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 Charts For Refrigeration. Solstice® N40 (R-448A) and Solstice N13 (R-450A) are Honeywell’s newest blends for commercial refrigeration. R-448A & R-407F are great retrofit options for R-22, R-404A, R-507, R-402A, & R-408A. Scan to learn more about our new PT Chart. Scan to learn more about calculating Glide. Pressure (psig)
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
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?
Detailed information on how to use the pressure temperature chart with refrigeration and air-conditioning gas products.
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).
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.
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.
A traditional PT chart includes the refrigerant temperature in the left column, and the different pressures associated with that temperature in the subsequent columns.
