Should the suction pressure drop below 57 psig, the coil temperature will drop below 32F causing moisture in the air to freeze on it (see Figure 4) causing no end of trouble. A R-410A evaporator running below 100 psig will freeze-up …Subcooling is a measurement of temperature DECREASE of a liquid below its saturation (mixed liquid/vapor) temperature at a given pressure. For example, water boils at 212° Fahrenheit at sea level (atmospheric pressure of 14.7 PSIA). If water is 212°F and at atmospheric pressure at sea level, you can be sure it is at saturation, which means it ...This free online tool allows HVAC professionals to quickly calculate Superheat and Subcooling measurements for both R22 & R410A refrigerants.

For a 410a refrigerant, the recommended superheat value is typically between 10°F and 12°F, while the ideal subcooling value ranges from 8°F to 12°F. However, these values …145 °F. 571.7 psig. 150 °F. 607.6 psig. 155 °F. 645.2 psig. You can see that this R410A pressure chart includes high and low side pressures at temperatures ranging from -60 °F to 155 °F. Higher temperature equates to higher pressure. Here are 4 examples of how you can use this chart: Jan 21, 2020 · However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20°-25° suction saturation below outdoor ambient. That means if it is 50° outside, the suction saturation temperature should be between 25° and 30° (on most systems). Key Takeaways Superheat is the temperature difference between the actual temperature of a substance and its saturation temperature at a given pressure. To calculate superheat, subtract the saturation temperature from the actual temperature.A: First, take all of your refrigerant readings and your liquid line and suction temperature at both ends (on a split system). This means superheat, subcooling, suction saturation (evaporator coil temp), and liquid saturation (condensing temp). For a TXV to do what it is supposed to, you need a full line of liquid before the TXV.How to measure SUPERHEAT and SUBCOOLING!
