r-22 high head pressure

[david2641]

I have a rudd condensing unit with R-22, at 90 degrees F. Can anyone please tell me what my suction and high pressure should be? Any help would be GREATLY appreciated. Thanks!

Between 0 and 120 on the suction side and between 0 and 500 on the high side.

Thank you so much for the speedy response! If you could narrow the ranges down for me it would be very helpful. Can you tell I'm a novice? Thanks again.

65 and 250

As a ballpark & it depends on a lot of factors, suction should be in the range of 60 to 80 & head should be in the range of 150 to 300.

I've got a 2.5 ton heatpump, @ 90 degrees in heat mode the suction should be @ 74 and the head should be @ 255.

Have a good night.You have all been a big help

pressures dont mean a thing. subcooling and superheat is what you want.

If you're not a DIY'er trying to glean this info but rather a novice tech, there's two things you should do. First, find and hold close to your heart a pressure/temperature chart. You can get them at any supply house. Secondly, when you're reading the R22 band on your gauge to get the temperature, look up toward the outermost band of numbers on the gauge. That's the pressure that essentially corresponds to either the evaporating or condensing temperatures of the refrigerant under the given conditions the system is operating at.

Next thing to do is immerse yourself in the world of understanding superheat and subcooling. You do that, you'll set yourself apart from the hacks and be on the way to becoming a sharper technician.

Look you have to at least give me some kind of gear ratio, for me to answer that question.

LOL...

Do you also need to know if the clutch is engaged, or disengaged. :}

no more then 3500rpm any more and the old pos will fall apart.

Wow! You like it hot don't you? How do you keep it from kicking off on HP switch?
