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., R-410A and R-22 is the higher operating pressures (approximately 50% higher on both the discharge side and the suction side).For example, a high-efficiency condensing unit using R-22 typically operates with a suction pressure of about 68 psi and a discharge pressure of about 250 psi at an outdoor temperature of 95°F., liquid and suction lines covering total linear = 200 ft. equivalent lengths up to 240 ft. The philosophy in designing a refrigerant piping system can be summed up as follows: Liquid lines should be sized as small as possible without exceeding the recommended maximum pressure drop of 50 PSI for R-410A. Liquid line pressure, An R-410A Pressure-Temperature (PT) chart is a tool used in HVAC systems to determine the corresponding saturation temperature of the R-410A refrigerant at different pressures.

Suction pressure is the measure of how the refrigerant, particularly 404A, is drawn into the compressor. Imagine it as the “inhalation” phase of your cooler’s breathing process. It’s the starting point of the refrigeration cycle, setting the stage for everything that follows. 4. The Goldilocks Zone for 404A, Suction Pressure/EVAP DTD Rule of Thumb Another common old-school rule of thumb is that suction pressure should be close to the outdoor temperature in an R22 system. 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., Hence, R410A refrigerant is considered safer than R22 refrigerant which is why it is a direct replacement for R22 refrigerant despite being slightly higher in GWP.
