During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG.24 Jun 2020
What are normal operating pressures for 410A?
System Pressures A normally operating R-410A system with the same condensing 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.2 Nov 2003
What should 410A pressures be at 70 degrees?
201 PSIG
How do I know if my 410A is overcharged?
- Increased pressure throughout the system, characterized by high head pressure and high suction pressure with low suction superheat;
- Increased flooding of refrigerant to the compressor during off-cycle, which may cause flooded starts;
What should Pressures be for 410A on a 90 degree day?
For R-410A, a working pressure capability of at least 400 psi is recommended (this includes recovery cylinders). Standard DOT recovery cylinders rated for 350 psi should not be used.
