R22 low side pressure at 70 degrees.

Re: low side ac pressure is high (70 psi) by wire2. Wed Apr 21, 2004 6:23 am. 70 psi is ok, depending on outside temp and cabin temp. The high side should be 250-300. An easy quick check is turn A/C on, feel the hi and lo fittings on the compressor. The suction (low) line should be cold, the liquid (hi) should be quite warm.All buses work at 70 psi low side. How do they make it happen, thanks. Reply: Matthew: The low side pressure when the compressor is running is a feature of the compressor's own pumping power combined with the properties of whatever device is being used to meter refrigerant into the system. That creates the pressure drop between high and low sides.Greetings, I am working on a R22 Lennox Split Heat Pump 3 ½ ton. The unit will trip on the compressor relief valve in heating. I was unable to test the unit S/C and S/H accurately, due to the High Side pressure building up so fast with in a minuet will be hitting 400psi and blow the low side would sit at about 50psi. I tested the RVR from cooling to heating, and even tested the unit in ...if the system has a liquid line or king valve you can charge into the liquid line. if not go to the suction like before. it is'nt always possible to do, charging into high side is fine, but at a point you will have to switch over to the low side.

Low side should usually be ~70-75 psi at that indoor temp and high side should be 170+psi (depending on how dirty your coil is and seer rating). And while you can't tell exactly how much refrigerant you're down without exact numbers for your system (metering device, indoor wetbulb, dirty coil) you can usually tell if you're low. That means that the pressure of R454B is the same on the high side and low side. ... we can read that the pressure of liquid R454B on a 70-degree day is 192.5 psig.

Mar 21, 2016 · Although it's really impossible to say what the "normal operating pressures" are for an R410A system as it's based on so many variables:load, humidity, condition of outdoor coil (clean or dirty), I would expect to see 120-135 on the low side and about 280-300 on the high side. Again, these are just examples.
