oil cooler

[ruffus]

hey guys i have a compressor that as oil cooler lines and when i hook i clear tube up to them so i can see if there is oil going throw it or not and when i turn it on no oil is pumped throw the lines is this OK or does it only pump oil when it gets hot can someone help:shrug:

These tubes dont contain oil. It is just a copper tubing going THROUGH the oil to cool the oil. Usually the two lines are connected in the middle of the condenser pushing partially cooled liquid refrigerant through.

Would be nice if some of the smaller hermetic compressors had oil coolers, would run a small waterloop in the system just to dump the excess compressor heat. Ruffus, which compressor are you talking about in particular?

[ruffus]

ok guys here is some pics now the lines that i am talking about the two that come out the middle at the bottom the ones that i have going to the cooler that i made with the two small fans on it

Usualy how it goes is discharge > first quarter of condencer out to oil cooler in. out of oil cooler connection two rest of condencer.

Nice crafting but I dont think you have anything circulating the oil/water?

[ruffus]

ok guys thanks for the help so now all i have to do is just re run the lines and use both the condensors the big one at the one end and the small one on the other or should i just run it out of my big condesor and then throw the oil cooler and then to the filter drier and just get rid of the small one

look at the pdf I posted! it will explain.

[ruffus]

yes i looked at the pdf and i will hook everything up like that and we will se how it runs thanks alot for the help guys

mmm you could just use those lines to run the suction through them.

that should cool down the oil, and prevent any liquid refrigerant going into the compressor when running an overcharged system.

Yes it would all so add tons of super heat increase specific volume reduce capacity, restrict suction flow and cause it to over heat due to stupid high discharge temperatures!

You never want the oil cold, not even cool, you want the crank oil to be moderately hot to flash off any droplets that make it back.


You need to think of the resualts of what you do, change one thing and it effects the whole system, you want as little super heat as you can safely get which is around 10 to 20 degrees with as little pressure drop as possible!
