I'd be going over it with a thermal imaging camera and make the invisible, visible. There may be something weird going on somewhere. A thermal imaging recording may show an interesting change in temperature over time somewhere that helps pinpoint the problem(s).
I was thinking compressors overloading or going off on high winding temp. Possibly even valve plates bleeding by. Without maintenance i suspect several mechanical faults. I know the compressor on the other group way at the end was going off on thermal OL because of the temp probe from the demand cooling was taken off..
Need a heavy duty cleaning with a non-acid coil cleaner, yeah to shut down the system to do a good job. Also check your heads on compressors might have bad valves with blow by
@@jrh86 Yea. The condenser badly needs like a serious cleaning, with a more powerful water stream, or something effective. But I don't think that all. Evaporators are kinda all over the ace but nothing is flooding
@@HVACRServiceTech Ah, thank you so much. I was scoring the internet looking to see if it was a form of a TXV or compressor type. The closest thing I came up with was that A6 is the section for HVAC to become a master technician for vehicles.
Slight loss of charge and excessive flood back on some circuits. A6 is suspect, the fact that suction pressure skyrockets when that circuit is calling leads me to believe either a stuck TXV or potentially even a failing EPR depending on how the rack is setup.

The Low Temp compressor 4? Did it get replaced recently, because it's been valved off and powered off for at least a month
A6 has a txv adjusted wide open.2 cents.
I agree. A TXV staying at 100% when the others are lower suggests there is a freon leak.
I think these have EXVs?
@@douro20 I meant to say EXV

Do we have any issues on condenser or evaporator airflow ?
@@jrh86 Yea. The condenser badly needs like a serious cleaning, with a more powerful water stream, or something effective. But I don't think that all. Evaporators are kinda all over the ace but nothing is flooding
I have seen several of you guys mention A6. What is that?
A6 is the Meat Prep area Walk In Cooler Circuit

I thought it was an Audi car😂
some how it seams like not rejecting enough heat those thick condensers get dirty in the middle and dont look bad
Check all your valves and if that’s not it get bigger or pistons 😂
Todas las repuestas están interesantes
check the subcooler if there is one
did you pump down all the compressors and see if they hold. you might have a compressor blowing by
I didn't because I would have to have the rack down for that. It may be something that I go back and do at night.
Bypass your EPR and run Rack Suction

OSHA would love to see this....being so close to that roof edge without any sort of railing.
