00:08 SUPERHEAT PROBLEM
01:48 REPAIR
02:32 MULTIPLE SUPERHEATS WITH THE JOB LINK APP
02:56 NEW WIRELESS PIPE CLAMPS
All right, i want to talk about the compressor super heat on this system. Right now i just finished a system repair and we're running 30. 36 degrees, compressor, superheat, that's real time. So it's going to change.
Okay, one of my evaporators is running 20 degrees, super heat and the other evaporator is running 17 degrees, superheat, okay, the compressor superheat and both of the evaporator superheats all work together, okay, along with proper insulation, on your suction line. Now this is foam tape. This is not proper insulation, but unfortunately, because the way the manufacturer designed this system, i really can't get anything else, but foam tape, it's better than nothing. Okay, because there wasn't anything on there.
When i got here today now, i would imagine that we're running higher than normal compressor super, not horrendous. Okay, typically, 30 degrees is the highest you want to see, but i'm not going to freak out if we're at 35 40 okay. But you got to look at a few things before you start going crazy. Look at this vibration.
Eliminator! The vibration eliminator is not insulated, so that is basically absorbing heat, bringing my compressor superheat up now. How much that's questionable? Okay, but the moment that i start adjusting on my evaporator super heats, we are going to change the compressor superheat. Okay, now both of my evaporator superheats are running a tail on the high side, especially since my system is at 34 degrees. My system is just about to satisfy right now: okay, um, i'm probably going to go ahead and adjust both of those expansion valves just a little bit to try to reduce the superheat, okay and but remember either way adjusting the super heat more super heater, less super Heat is adversely going to affect your compressor superheat.
So keep that in mind all right. We have one of my expansion valves right here and we're going to try to bring the superheat down so we're going to adjust it. So i adjusted it. Four quarter turns down.
That's one full turn down and we're gon na. Let the system stabilize out and see how it reacts all right. So now that i made those adjustments, my compressor superheats at 29 degrees right now, which is really good. I also brought the box temp up to about 37 because i popped the door open.
So that way, it wouldn't satisfy looks like i have one evaporator, that's at about 17 degrees right now, and i have one evaporator, that's at about 14 degrees right now, so we're looking pretty good, i'm gon na let the system run a little bit longer, but i'm Already extremely happy with that compressor, superheat all right, i made another adjustment and i got ta say i really dig the fact that field piece lets you do. Multiple super heats, so compressor. Super heats, 26 uh, evaporator, 116 evaporator 213. We're gon na give it a little bit more time to stabilize now it's really cool because, with the field piece jobling system, i'm able to wirelessly connect to the walking cooler evaporator, that's below me right now. Okay, i have the jl3 pc, temp clamps on each evaporator and that's how we're getting this measurement right here: okay and this measurement - and then up here i have field pieces, new, jl3, lc, large, pipe clamp. This can go on up to four and an eighth of an inch uh refrigeration line. Super awesome super cool, instant reaction. You can see right now uh here we go right here, we're at 28 degrees, so i open it up and we're gon na lose.
But the moment that it makes contact with the rapid rail technology we're gon na immediately see temperature. Okay, all right. I just connected it back. Uh looks like we're at 29 degrees superheat.
So it's instant readings. That's awesome! Okay, uh! So this system, i'm gon na, go ahead and give it the all clear uh, even though my evap superheats just a tad high, i'm not going to go cranking on it too much. I've already made some adjustments and i dropped it significantly. So i want to let the system stabilize out.
How far where the evaporator coils are? Are you using a signal extender for your fieldpiece probes?
How many voltage does this air conditioner runs on? Service area Orleans??
What happened to the trutechtools discount code
Im much more used to seeing and handling the larger versions of this type of compressor. When going up in load size I can see the benefits of staged hermetically sealed units but I just like big old semi-hermetic compressors. (I even talk to them sometimes 🤣😏)
That's a great video of a New tool everyone would like to have!
How you get field piece app to do multiple measurements
Do they make the large clamp wired and not wire less? Be nice if you could plug that bad boy to a fieldpiece meter too
Great job and video
Thanks for the bonus video. I have been wanting to get the entire set at trutech for about $700 i believe, but for someone working for a company, I don't see the cost benefit. Its just too expensive unless the company provides it. Instead I would go for a better leak detector to spend my money, because the company provided one is terrible, I am always guessing on leaks unless I see oil. Are you in Orleans ?
OKAY?!
Back when I worried about superheat, we just checked evap superheat and not compressor superheat. What gives and when did comp superheat become important? I mean as long as evap superheat is 10 degrees (per sporlan at the time) who cares what comp superheat is? I've never seen a spec on it but maybe it's a new thing.
how do you know what your superheat/subcooling should be?
I saw those on Feildpiece Instagram post. They look nice to read on bigger pipe nice to see them out in the feild. Good luck on the new clamps. Nice video for sure. Thank you bud.
Those temp probes are awesome. Since it seems you are literally adjusting valves to a tenth of a degree, do you ever find the need to calibrate or at least check them against a standard of some kind?
#373 thumbs uP
What is the maximum distance you can use these clamps? Nice video as always Chris.
Hey, slightly confused. How are you measuring superheat without a gauge pressure or do you have pressure probes attached somewhere out of sight?
Great vids by the way, as an ex refrigeration engineer from the UK it’s really great to see you posting all these and including some great faultfinding walkthroughs. Keep up the good work 👍
Great video for learning. Thanks Are you in Kanata ?
Hey Chris thought superheat on evaps need to be between 10-15 degrees max and on compressor max 20 degrees so we ensure compressor cools down and not less than 20 to ensure no liquid returns back. Correct me if im wrong. Keep doing these great videos. Greetings from Cyprus Service area Kanata??
Wow amazing video
I love This channel
Oh boy ! I work on chillers with massive oversized suction line and it's always a struggle to measure suction line temp ( to verify the EEV's sensor accuracy ) which means : I'm gonna need to somehow find a way to get my hands on these new super wide jaw probes … Thanks to Chris , now I'm gonna be obsessed with a new tool so , cheers for that !
I’m excited for these clamps. I give return gas temp priority over compressor/system superheat. We work on some units that will have a 50° superheat by design but the return has temp is low enough to keep the compressor cool and operational. It’s somewhat splitting hairs, but I think it’s worth bringing up.
At first sight, before watching your video, I thought those yellow things were bananas.
Gonna need a steady Sub Cooling Of 10 or more before you start setting TXV valves. On A cap tube or piston style feed, then go straight to SH, But NEED to know SC First with valves. MY OPINION. Mind Full This in in perfect land Temps, Which don't exist. LOL, And the story of opinion, everybody got one, But This One thing to get in your head starting out is learning WHat your refrigerant Is doing and What it needs to do to get what temps you are looking for. If you get that down along with diagram mastering/Meter work. You can go as far as you want in this field , My Mindset, 32yrs and going
Thanks for the information !
That looks like a different compressor style than the hermetic bottles you usually show. I take it you don't see this type often.
First i thought there where Bananas in the thumbnail.
Cmon guys let's help Chris reach a 100k and. Silver Play button. Tell all your friends, coworkers, whomsoever to subscribe and like.
Congrats on 90K Subscribers ! Good video ! Only 10K more and u Get the Silver Play Button !!! You should be there in no Time. It Will Probably be Your Christmas Gift from You tube. Let’s Hope ! Congrats again ! You deserve it !
I love the Job Link probes. I picked up the full set about 6 months ago after watching you have so much fun with them. Are you not using MeasureQuick anymore? If so, I don’t blame you. Bergman is THE MAN, but he kinda went overboard with the App. A bit bloated in my opinion. I’m sure some people love it.
I have absolutely no reason to watch these videos, but I kind of want to get some AC tools and learn now lol Service area Nepean??
Fieldpiece is going to take my paycheck with those new temperature clamps and job link probes. Is there a Job link probe kit? I've seen some post on Facebook about people buying as a kit. Are you in Ottawa ?
I know you’re kinda just showcasing these new larger probes and they look great by the way, but I would love to see a longer video of this. Very interesting!! I don’t think I’ve seen a total superheat video like this. Your videos are top notch. Thanks so much!!
Yay a bonus vid!
Nice explanation for the super heat thanks ! Keep it up
So what should the correct amount of superheat at compressor? Are you in Barrhaven ?
Chris got some funny info..
People who watch videos of blocked drains, also watch your videos..
Saw your channel mentioned in comments to a drain addict video..
So find some blocked evap drains, and your channel will hit 100.000 in no time👍
Is “compressor” superheat the same as “system” superheat?
Good stuff Chris.. great explanation
great one i was wonder if they would of made larger clamps so we can use it on the chillers i am a chill water tech lol
Saludos desde República Dominicana 👍👍👍👍👍👍👍👍👍👍👍
Im number 5
Morning brother almost to 100k !!!!
Just happened to be on your channel when you added this video. Keep up the great work!
