Refrigerants - Saturation Pressures vs. Temperatures Temperature and pressure diagram for constant boiling refrigerants - imperial and SI units.

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.

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.

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.

Using an HVAC refrigerant pressure temperature chart is necessary to be sure a unit is operating correctly. Below are three free pressure temperature charts that can be used to troubleshoot an HVAC unit.

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?
