The only oil that should be in the system now is in the lines and condenser. I guess I am getting confused between the system requirement vs what should be in the compressor. Does the compressor have a sump or “oil pan” that I need to be concerned about or does all this even out over operation? Probably over thinking it again.

 

I think the oil is just contained in the compressor itself. No separate reservoir, or oil pump there.

Did you add the requisite amount of oil to the other pieces as your changed them? If so, then 5 ounces for the compressor.

 

Have not added any oil yet. I had planned to add the requirement during charge before I decided to replace the compressor. I guess what's important is to add oil per the system requirement which according to the service manual is 7.75 oz and let it migrate where it may giving compressor first dibs. Labeled on the old compressor is 240cc which is a little over 8 oz. Was sort of shocked with the low amount in the old compressor. There was more oil in the old accumulator than the compressor.

 

The oil will settle out of suspension wherever it happens to be when the system is drained. If its slow, a fair bit of oil will stay in the system, if it's quick, (like, the condenser being crushed in an accident.....) the oil blows out right along with the refrigerant.

 

As far as my understanding of AC systems is, the oil will level out by it's own and it is only necessary to have the correct amount in the compressor. So if some components in the past were exchanged you might have lost some oil. If it's only a minor amount you can add it via your AC service trolley after vacuum test the system. Or tell the shop the amount they had to add.

Worst case scenario would be a mix of used components, like you did an engine swap including the cooler package. In that case I would fill the compressor up to level, put AC gas on it, let it run for a good time (verify its function), evacuate the gas again and check it. A lot of effort but the only way I see to get back to a known to be good stage.

 

our understanding of air conditioning systems and the role of oil in them is generally correct. Oil in an air conditioning system (ACS) is necessary to lubricate the compressor and other components. While refrigerant can circulate through the system, oil tends to settle in various components, especially the compressor. But there is always a risk, it's like online casinos, by the way thanks for the information https://casinosanalyzer.com/online-casinos/punt.casino you have helped me a lot with my game selection. If components have been replaced or work has been done on the system, it is possible that some of the oil has been lost in the process.
