Temp (°F) Pressure. Temp (°C) What is r410a’s suction pressure? When operated at a 35 degC ambient temperature, the suction pressure of an Air-Conditioner with R410A refrigerants ranges from 115 to 125 Psig. At these operating conditions, the discharge pressure is around 400 Psig. R-410A operates at 50 to 70% higher pressures than the R-22. Related Articles: These liquid-line restrictions all cause the evaporator, compressor, and condenser to be starved of refrigerant. This will cause the following symptoms: Low evaporator (suction) pressure; High evaporator and compressor superheats; Low compressor amp draw; Short-cycling on the low-pressure control;The main reasons your compressor will have simultaneously low head pressure and high suction pressure is due to: Bad or leaky compressor valves. Worn compressor piston rings. Leaky oil separator return line. Your compressor valves may become inefficient due to poor sealing from dirt and debris deposits.

With R-410A, the same unit will operate under the same conditions with a suction pressure of 118 psi and a discharge pressure of 400 psi, as shown in Figure 1 on the next page.

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. This chart is essential for HVAC technicians as it helps in diagnosing and maintaining air conditioning systems.

Worn compressor piston rings. Leaky oil separator return line. Your compressor valves may become inefficient due to poor sealing from dirt and debris deposits.An R-22 evaporator running at 40F saturation temperature will have a corresponding pressure of 68.5 psig. 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 just ...The low side pressure of a typical R410A mini split is between 110-140 psi depending on the operating conditions. Though it can vary, the low side pressure of a mini split should not fall below 100 psi or raise beyond 160 psi. The working pressure of mini splits is depending on factors such as the weather and cooling load.

Suction Pressure / EVAP DTD Rule of Thumb Another common old school rule of thumb is 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.

Get it up to 200 and it would be grossly overcharged. It will be likely running in the 35 to 45f degree saturation (boiling point) range, 108 to 131 psi. The high side has an even greater range. The pressures will vary as the operating conditions like return air temperature, outdoor temperature change.This is a table that tells you precisely what the pressure of R404A is at a certain temperature.
