Refrigeration piping of a walk-in box

[@danielduplessis1582]

Good job Dave. Very neat. Experience has taught me to make separate holes for each suction and liquid line , I also install pvc sleeves....Nuisance call outs on weekends and at midnight because the luquid line has rubbed on the cold room panel

Why didn't you turn the condensing unit around for easier servicing, would have been just four more feet of tubing.

[@NorCal-refrigeration]

Contractor placed it not me. And there’s a nice flat rubber roof on the other side. You’ll see on the start up video

[@nehorayaudio]

Why did you install smaller size suction line pipe smaller than what's out of the evaporator It is totally unprofessional !!!!!!

[@NorCal-refrigeration]

your lineset size has many factors when sizing, coil manufactures provide you the largest. its professional to size your line set correctly. someday you may learn how to be a refrigeration mechanic. 🤣🤘🤣

[@nehorayaudio]

@NorCal-refrigeration if you need to down size your evaporator line out maybe you choose a coil that is too big for this room Or a small unit for this evaporator More ever between the evaporator and and compressor you have such a pipe length that is even recommended to take a bigger pipe. Suckers don't die only replace Poor customer 😢

Did you use rigid acr pipe for this job? You bent it quite easily without annealing, it looked like.

[@reluctantprophet]

Dave, piping looks great but man if I see an apprentice out there using your technique to find center on their suction line hole he’s going to get plumbed up. You show a lot of good practices and measuring off the side and back of box to find true center might be some good info to throw in there...

[@throttlebottle5906]

some of us just have a good eye, I can generally eye ball a hole 3' distance away from starting point and come up less than 1/2" skewed. granted I've been doing various/many construction fields of work since a young brat, electrical, electronics, computers, automotive and more. yes, I have made my share of mistakes and learned the hard way(and still do) Murphy's law has us all the nuts and teetz LOL. it's how you properly deal with, admit to and correct your mistakes, that makes us better humans :)

Once you get the knack for it Annealing your hard ACR and bending it is easier and faster than cutting it and making an elbow and having to breeze it back on again. And you never ever have to worry about a leak at the two braise points.

[@NorCal-refrigeration]

I’m a bender master.

[@craighvac1808]

Do you need to anneal the tubing before bending?

[@tcphvacr9950]

Yes you do. If you noticed, his tubing was discolored at the bends.

[@sterlingarcher46]

Very neat job Kung Fu Dave , as long as you don't become Kung Flu Dave innit ! Btw , I was told that the bulb has to be " counterflow " to the suction line , meaning that the capillary tube outlet faces the evap , is there any truth in that ? Cheers Dave , very nice 👌.

[@Artisan.HVACR1]

Good work. Your preference for hard pipe ACR tubing rather than soft copper linesets caught my ear. I find it interesting. I also think your way makes the final piping layout look better than lineset piping. The extra step of having to insulate the suction line is worth it. Your work is good.

[@NorCal-refrigeration]

Thank you.

[@Gary-ts6dh]

4:45 - Since you can safely assume your walls are plumb, you can use a tape measure to pull the exact center off the walls instead of guessing where the center of the pipe is. That way your copper will be plumb in all directions. 15:18 - Any concerns about scraping the inside of the insulation over the end of that unprotected tubing getting into the pipe?

[@NorCal-refrigeration]

I screw up the insulation all the time because I get ahead of myself and forget to tape off the pipe. Like all the time.

[@martydzielak7151]

Layout and drill from above, both hanging bolts and pipes. Drill a smaller hole along side suction for liquid line. Takes a little planning and measuring, much better job. Almost impossible to seal piping pentration with liquid and suction in the same hole, super critical in freezer aplication.

[@tyhuffman5447]

Turd herder pipe. It looks like the liquid line is touching or wants to touch the aluminum box on the inside where you made the hole. That could be a failure point, ripe for rubout.

[@itsprimetime9865]

its called silicone

Nice install. I didn’t know you could bend acr.

[@jerrywhite410]

How come you didn’t put the evaporator close to the back wall of the box?

[@NorCal-refrigeration]

It’s a bi flow coil

[@ka-i]

What is the purpose of a p trap

[@throttlebottle5906]

to help with refrigerant oil return to the condenser/compressor. while the system runs there's always some oil loss via vaporization and misting from the compressor into the system, the trap collects that and allows it to be sent back vertically in slugs or to aerate back into a vapor/mist mixed with the refrigerant gas so it carries back vertical. I'm NOT a teacher nor engineer, so my explanations may not always be the best :)

Plumber copper is M type. K type copper is just like L type nitrogenized and for refrigeration expect it has a much thicker wall. Have ran lots of K type at Costco's very heavy stuff. You'll also recognize K type because it'll come with an orange plug rather than a white one.

[@tarunm4534]

@@adriancervantes19 K type is heavy and in Costco you might have run for glycol system. We ran K Type for VRF system (80 ton system) and depending on the project requirements (client) it can be designed. The Ontario building code says L Type copper minimum is required for plumbing. We have green plug in K type copper and its nitrogenized. I think I saw L Type with orange plug. Depending on local building codes it can vary.
