​@@arthouston7361 As the owner of a 4.0L Jeep, and as someone who has worked on several 4.0L Jeeps, you're not wrong. Although, by some miracle, mine doesn't leak a drop! Previous owner put over $1,000 into making sure it didn't leak before I bought it two years ago. It's not a question of "IF" it'll start leaking, it's a question of "WHEN" and "WHERE" - but at least for now, I have one of the extremely rare non-leaking Jeeps. I've gone and jinxed myself, haven't I?

Those all-in-one boxes/islands would probably be good ideas if they were designed as modules with repair in mind. One section has a problem? Just pull a few bolts and that section can be removed for easy repair or replacement. But of course that makes the initial purchase price much higher so they don't do it.

Frankenstein outdoor unit lol It needs a hundred oil traps as the pipe work falls down to the multitudes of evaps lol😂😂😂

I'm amazed at the lack of food scraps in the reach in section!

For these systems an oil separator in the discharge line seems like an idea to make the compressors last longer... Have it separate out a good part of the trapped oil and link it back to the suction with a capillary tube and cut-off solenoid for the pump-down. Considering how much time you spent on just this service call, it's likely cheaper to install these than just call you every other year. But hey, if the customer doesn't want to do it, it's more money for you later. Win-win.

Yeah but to be fair it would likely plug up the return line because they don’t do good maintenance

@@HVACRVIDEOS That is a very valid concern. Any added part is another possible point of failure.

Get that system a hotdog for all that mustard!

Oil separator, Chris... It would solve this, use either a piston with a pulsing solenoid or a small capillary with pump down cutoff solenoid. Catches something like 98% of the oil, which would not solve the problem but definitely delay the onset of the symptoms. Otherwise 10/10 vid.

What's this chris struck oil dude ya gonna be rich as heck 😂 lol

when that solenoid to Tee Joint cooled it shrunk and pulled back, hopefully there is still enough engagement @11:31 mark

A suggestion that I could make is to resolve the oil issue is to put a cap tube after the txv to the suction line after the sensing bulb. Make a p trap with the cap tube after the txv to let oil get trapped but still let a little refrigerant after it has cleared all the oil out. This is the engineering mind that I have going that says how to fix the issue. I have run into this same issue before with failed power heads even on box systems. More info for the other techs in the field to pickup on when they find things like this.

12:07 - Yeah. The boss always gets the easy TEV!

one of our guy's hand got burned when he was unsweating a condenser and oil caught fire and spewed a jet of flame, even though the system was at 0 psi... refrigerant can get trapped behind oil, that's why it sometimes "burps" doing recovery and the microns shoot way up. we now no longer unsweat compressors, dryers, evaporators or condensers

If the Restaurant doesn't want to lift the rack to do a proper repair, is it possible to use a thick epoxy resin to coat the floor of the rack instead? Use a thick enough Epoxy and it should flow into the holes and plug them up, then set into a strong plastic sheet sealing the rotten area away from any water coming from the rack area itself such as when you're cleaning it... That won't be cheap, but it should cost a HELL of a lot less than lifting the entire rack to replace the rotted sheet metal would...and it would have the benefit of being done while the rack is running too...

Holy oil Batman.

You shaved! :D No, good job! Love seeing something that makes you guys go "Huhh.. interesting"

I love it, grind...grind... Darn it! 😅

Polishing the ...

A big issue might be, the txv entering on the bottom and the sucction leaving at the top. Back in trade school we talked about it because the refrigerent has to move up against gravity and the oil falls back inside and stays down, im pretty sure if enter from top end put a nice p trap in there it might fix the issue. But i know its a pain since you dont have any space in there

Like always great info Chris. Thanks from florida

I have not finished it, but I ❤ this video. Great work. I also like the idea of using that wire brush for cleaning the copper before disassembling the component.

There isn't enough refrigerant velocity through the txv when the powerhead is bad, traps the oil.

Awesome video great info

OMG! So much oil coming out, that compressor is done for!Awesome video! Be careful working on these units!

We take care of a Kairak rack for one of our customers. I’m dreading the day I have to make repairs like this in their extremely busy line. So far since I’ve been with this company (1.5 years) it’s dumped the charge 3 times from lines rubbing out. They refuse to do any maintenance.

Send that system straight to the hospital. (Serious infection).

Yeah I do the same, I defrost the drain line while using a shop vac to remove the water first than the pan chiller gets defrosted last if it’s not already defrosted

Pumping a scroll compressor down to 2 psi is a no no.

Awesome in-depth video, Chris, with great team work. You put a lot into it going through everything and covering the important details. It was one thing to see all that oil come oil which makes you feel sorry for the compressor, but it was quite another to see your new 'look' when it came to the closing commentary! Is compressor oil actually from the proverbial 'fountain of youth' (which would explain the high cost of compressor oil as well as why HVACRs never seem to get old or at least age much more slowly), or does it make your make your hair fall out (which would explain the lack of facial hair and cap)?

Out of curiosity: What kind of gaskets are in the solenoid valve you brazed in? The valves our company usually uses have rubber o-rings that get roasted if you do not cool the valve during brazing or disassemble it before hand… great video as always. Keep it up.

Discharge oil separator like they use in ultra low temp refrigeration is a fantastic idea if they're gonna do stupid stuff like having the suction on the top instead of the bottom

Yeah but like on a real rack you need an oil separator oil differential valve and a oil reservoir

Add oil to that compressor for sure lol

Shows the process of troubleshooting a technician has to do when the problem isn't obvious.

Delfield coils do this a lot.

I had a contractor install a dual evap in a walk in and they left the individual temp controls install so only one evap would run and rhe other would accumulate all the damn oil so id lose all the oil in the compressor. I had to twin them. Running a compressor ar half capacity with large line sets is a recipe for disaster

About 50% sure that’s a CCF

Would using the exhaust of the vacuum to blow all the water out work? That way you wouldn’t damage your vacuum.

Doesn’t the oil coat the inside of the pipes and prevent heat transfer while the refrigerant still goes through the coil? I don’t think it traps refrigerant in the evaporator.

Brazing a2l might be sus?

Good job Chris, Shaven face for a change.

What do you think about the new R454b that will replace 404A?

Wow

did not know land rover also made coolers.

So looking by the setup looks like a P.F. Chang’s. We do work for them here in Chattanooga. They have almost identical setup with custom built stuff and condensing unit is in rack. Ended up 7/9 of their evaporation coils had leaks. We ended up going back with all new heat craft coils since somehow the coils couldn’t be sourced. Leaks were so bad we were going back every month to top off charge

@taylorj9920

They were sourcing those original coils from a vendor that was getting them custom specd and built in bulk orders for those coil assemblies they we're installing during their retrofit shutdowns

Question... was there also predator blood/ leak detector in that system?. Oil looked suspicious to me..

Looks like a PF changs

Ole pf and their messy setups

I don't understand how people can let their equipment get to such a terrible status, I know there's been worse but this is bad enough for a total replacement of the system (In my eyes at least)

😋

74 thumbs up

👍🏿

I hope you know the risks of brazing with those types of gloves on. You should be using leather and not something that can melt to your hand. Just FYI. Safety first.

If the roof is leaking I would say in that situation a diesel powered air compressor would be a better option ? No?
