I just did an electrical repair on a reach in cooler and there was one of these every 20 ft or so on the suction line. Now I understand why. Thank you for helping educate us.
My 1 ton bluestar split has issue like blower is not throwing complete air it stuck in some places. Air flow comes with whzzzz whzzzz sound. I can fell the chillness and cooling. But air out flow from blower stuck in one side. My Ac mechanic told the same u trap. Is the u trap recommended for my issue. I changed outdoor eveporator coil my blower fan is good no issues, I did full water service gas level is also good.
thank you for useful video so i have a question " when the compressor have not full capacity and velocity decrease , the oil in traps are a node that is very danger, do you know how to oil in traps do not a node anymore?". I'm really happy to wait your answer.
I'm going to install a 12k btu mini split outside compressor about 6' above the inside evaporator. The unit comes with 16' tubing - aluminum with copper ends, so I don't want to cut the tubing. I calculated I need about a 10' line. Some people coil the extra line behind the compressor. I was concerned about oil flow, but after watching your video it seems that the coiling would create an oil trap and be beneficial. Do I need to be concerned since the entire line is only 16' and is there a best practice to follow when mounting the compressor higher than the evaporator?
I always try to go back and forth behind the unit to hide extra piping (if I'm closer than 10 feet) most ductless have an oil return cycle. That should return any oil that is I the evaps. Having oil traps in a ductless should be avoided if possible. Makes for a quieter system. (Less chance of the swishing or gas noise some people hear for time to time)
The problem is the loop (especially if more than one loop) is hard to protect from UV/sun light, so the factory line set insulation crumbles off and is hard to re-insulate
@@golddroger31 so your telling me if I install a compressor on the roof with an oil separator(which collects the oil from the discharge side of compressor then pumps back into compressor) I’d have no oil ?
@@adrianlieutier7159 Correct!, an oil seperator ''catches only'' about 90-95% of the oil so eventually the oil will go away, problem is how to take it back.
@@klidaras11 You are considering HVAC installation Scenario 1 - Condenser is ABOVE evaporator. However when Evaportor is Above the Condensing unit, is it obligatory in your opinion to have oil trap? Just as shown in: 04:01
@@adrianlieutier7159 obviously these guys who are telling you this don't know what an oil seperator is an oil seperator is installed when you have a very very long pipe run either discharge or suction line the Oil seperator is used to pretty much prevent the oil Running away from the compressor and get stored in the seperator and pushed back in to the compressor

Perfect video on oil traps!
Aoa.Very knowledgeable Explanation. Thanks

Are there auto drainbacks like solenoid controlled with discharge? I know they make em for air compressors but those work with float valves..
Typically a check valve on the discharge line of compressor prevents any refrigerant migration

Terimakasih.....ditunggu vidio yg lainnya
so i'm seeing folks install these mini split systems ans coiling the access lines next to the outside unit .... is this a problem ?
Not for R-410a systems. It was a problem with the older R22 refrigerants.
The problem is the loop (especially if more than one loop) is hard to protect from UV/sun light, so the factory line set insulation crumbles off and is hard to re-insulate
We dont use 45° fittings in refrigeration. Also inverted p traps are usually installed at top of riser.
Oy... nice effort, but this format needs work.
It fails in it's primary objective, which is good communication.
Sir can you help me improve our system. We are now experience oil logged in evaporator. The compressor cannot collect it back to the crackcase.
Nice 👍
Wouldn’t installing an oil separator on the compressor stop all these issues?
Not if compressor is on the roof. You wouldnt be getting any oil if no trap, usually commercial applocation when compressor's on the roof

Thank you
informative 👍
No comments and no views I guess nobody’s doing any traps
I do traps, in building with 4 floor and up
The wiggling hand is annoying and distracting.
