WHY IS THE AIRFLOW SO LOW?

This was a call on a kitchen ac not cooling properly, right away we noticed it had horrible airflow because the unit was filthy.

I think your hitting the nail Chris , We always have to make the balance between perfect and functional. Now with the covid ... it is a whole new game . I have many customers who have cut labor loads down dramatically. Forklifts are sitting idle and pm service is not being done. Fast forward a few months and they find the industrial battery is dead , now it is up to us to see how we can help the customers... Basic point is , I make money from them making money , if they can't make their money , they sure as S don't want to pay me .. if I take it like a wild man , they never call us back .. fine line , customer relations are huge . Be safe brother !

I write up the issues and concerns and make recommendations, get the pricing, they never approve. Then it breaks again and they dump money down the drain not wanting to fix it right.

13:43 I been watching from the beginning. Call me crazy and may sound like its stupid. But during the time stamp i put on this comment, If you have a pack full of washers and maybe some longer screws. You can raise the fan motors up another half inch, and could make all the difference in the world with how its flowing the air past the condenser and up out the top. because the fan motors are hanging from the spider web and facing down. If you raise the assembly air has less of a gap to pass and cycle back around inside the case and around the compressors.

His meter (fieldpeice SC480) has a special mode for it. You can't do it with a normal meter. Presumablly the meter uses an internal reference clock to extrapolate the waveform from the L1-L2 measurement and compare it's phase to the waveform from the L1-L3 measurement.

How come some a/c pro's call liquid refrigerant oil?

[@44R0Ndin]

You might have gotten confused. There's liquid oil in the system to lubricate the compressor's internal moving parts, and there's also refrigerant which actually moves the heat around. Both are required for the system to operate. The refrigerant is what usually leaks out first (barring a compressor casing failure) however the refrigerant will also carry a small amount of oil thru the entire system, so when you spot oil on a refrigerant line or fitting, what you have found is the stuff that got left behind. The refrigerant and oil mixture leaks out, then the refrigerant evaporates and disperses in the atmosphere, but the small amount of oil that was suspended in the refrigerant gets left behind coating the surfaces near the leak. I hope that helps explain it. This is also how refrigerant leak finding dyes work. They get carried by the refrigerant to the source of the leak, and they get left behind by the refrigerant. The difference is that the dye will glow under UV light, which is helpful if you need to find a very small leak in an area that's hard to get to and you can leave the system running for a day or so to let the leak push some dye out to a place it can be seen.
