be used for refrigeration. Typically match R-12 i. condenser/hot conditions. Loss of capacity . -12 refrigeration systems. The pressure and system capacity match R-12 when the blend is running in a 10°F to 20°F evaporator, and there is typically an 8°F temperatu.
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.
Use gauges to determine the pressure at the condenser coil outlet, and a thermometer to get the actual temperature at the same point. Use the Bubble column to get the bubble temperature. Subcooling = Bubble Temperature - Actual Temperature.
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
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.
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). Example: What is the pressure of 134A freon at 85°F?
