Eric Mele explains how oil works in parallel rack refrigeration systems.
From the discharge line, the oil-refrigerant mixture goes into a large cylinder called the oil separator. As its name suggests, the oil separator removes the oil from the refrigerant; the filter may be inside the separator or beyond it. (In this video, the filter is inside the separator.)
At the bottom of the separator, there is an oil float. From there, the oil moves through a pipe back to the oil reservoir. Some reservoirs, like the one in this video, have a sight glass before the inlet that allows you to see the oil going into the reservoir. There will also be some sight glasses on the reservoir that allow you to see the oil level inside the reservoir.
From the reservoir, a pipe carries the oil to the oil regulators on each compressor. You can use those regulators to adjust the oil level for each individual compressor. These regulators usually also have a sight glass.

So now we're going to discuss all the dead dino juice that makes this possible oil. So, as you can see the discharge line going into this big oil separator here, this big cylinder, this is going to separate the oil back out of the refrigerant. Now the separator might have the filter inside of it or there might be a separate filter. In this case, the filter is inside the separator, the floats on the bottom there and this little pipe here.
The oil line is coming out going up and into our oil reservoir and on this one they put a sight glass in line, so you can see the oil flowing into the reservoir going in the top, and you have sight glasses to check your oil level from There it's going to go out of the reservoir it's going to flow over and there's a t coming to each oil regulator on the side of the compressor which you can adjust the oil level individually in each compressor. You can kind of see the oil sight glass in there and each compressor is going to get one of those in order to keep the oil levels all happy, so the next time you're eating some frozen chicken tenders. Thank a dinosaur we'll get into all the specific components in later videos, thanks for watching thanks for watching our video, if you enjoyed it and got something out of it, if you wouldn't mind hitting the thumbs up button to like the video subscribe to the channel and Click the notifications bell to be notified when new videos come out.
