What are normal R22 operating pressures?
R22 gauge pressure is 10.9 bar or 158.2 psi. High side pressure typically varies by equipment and metering controls. Low pressure or suction side typically varies by equipment. Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees).
What is the normal operating pressure of R-410A?
418 psig
A normally operating R-410A system with the same condensation temperature of 120 degrees and a 45 degree evaporator saturation temperature will have a high side pressure of 418 psig and a low side pressure of 130 psig.
What should r22 pressures be on a 70 degree day?
If the outdoor temperature is 70°F, a refrigerant bottle outside would have a pressure of roughly 201 PSIG. If the outdoor temperature is 110°F, a refrigerant bottle outside would have a pressure of roughly 366 PSIG.
What should 410A pressures be at 75 degrees?
217 PSIG
Likewise, an R-410A recovery bottle with a surrounding air temperature of 75°F should have an internal pressure of 217 PSIG. When an air conditioning system turns on, the large vapor line will lower in pressure while the small liquid line will rise in pressure.

What is the correct suction pressure for an infant?
Adjust wall suction. Recommended pressures should not exceed 80 – 120 mmHg for pediatrics and 80 – 100 mmHg for neonates. Cleanse hands and put on sterile gloves.
