My mind is blown, glad I'm not the only one whose brain has turned to mush staring at SC data and not having a clue at what I'm looking at and what to look for. Also, your right, today was one of those days I seriously considered sending my application to Walmart.
Servicing VRF is always an uphill climb that sometimes only gets harder. Don't give up man and always, always, always work through it one item at a time. The 3 pillars is designed to help our brains process something that is complex and turn it into a form that is easy to digest. We eat an elephant one bite at a time.
Great video Roman. Mind blown! 🤯 I would like to send you some scenarios that I find as well when we have a system that has more capacity tonnage on our fan coils then our outdoor units. (135% Connection Ratio) the data can get confusing at times when we have a full 100% call for heat on our fan coils.
I can do you 1 better and create a video on 200% Connection Ratio in Normal Cooling or Heating Mode and the reason why we should only be benchmarking systems at 100% capacity call. Send it all the same though!
Depends, a subcooler even at a max open position, can still only add a specific amount of heat transfer to liquid leaving the circuit. Yes you can send data to CheckerPolice@gmail.com however no guarantees on turn around time.
Thank you for the great and informative explanation! I noticed the software you used during the explanation, which seems to be a simulator for the refrigeration cycle. Could you please tell me the name of this software and how I can access it? Also, were the refrigeration cycles included designed by you, or are they built into the software? Thank you so much for your time and effort!
It's gonna be a game changer when we can get AI to look at the data and give us an idea what is going on with the system. It'll be able to continuously learn and remember each problem it runs into and use that data to better help diagnose.
They have AI learning already enabled in a lot of this equipment, there is even an Automatic Data Analysis Tool used by Japan. However it has it’s limitations. Data sometimes can only get you so far until a site evaluation has to be done to find the why.
Excellent video with invaluable information, Roman!
Thanks, this is just the tip of the iceberg my friend. There are a LOT more to come!
@@RomanBaugh Question: Is the (0x-sensor)_Condensing_temp.(TC) being read from the pressure transducer (S1NPH) and then converted to temperature?

🤯🤯🤯 great training video as always roman 👏👏👏
Thank you! I am happy I get to help you on this journey of learning VRF!
More videos please! That was epic!
I hope you enjoyed it as much as I did making the video.
thank you mr. roman 🌹🌹
Of course, thanks for watching
These are SO good
Love it
Thanks for watching!
Awesome video man! Is that refrigerant flow diagram just a PowerPoint? Can it populate live data?
It is a training program that I posted a link for in the comment section of several of my videos.
Brain officially explodes! 😅
Great video again
Thanks for watching!
Great video Roman.

@@RomanBaugh Copy! Send me your email. Ill send it your way today.

Great info! Would be interested to see you go through a unit that is running correctly
That’s a great idea and I will add it to the list!
Roman where can I get the list?
I will add it to the description as a link but it is in the VRV/F Tech Talk FB Group and on my LinkedIn
Do you accept data for review? Would a stuck open subcooling valve/eev cause low inlet receiver temperature in heat mode?

Wow Great Job, The VRV diagram how can i get that. I'm currently building a VRV HR air to water system,
Hey, I shared a link in the comments on a few of my videos that has all of the simulators in it.
@@RomanBaugh I found it thanks, wow you peppered the you tube with some great vids.

You can get a copy of all the simulators that I use for Free here.

Holy crap I’ve never seen a discharge pipe temp that hot before. Hottest I’ve ever seen in the field is like 212
That just means your systems are in fairly good shape! The highest I have seen in the field is 305 degrees F, compressor was smoking.
@ I really hope I never experience that. I start stressing when I see 200.
Keep them following! How do I email you data?
My email is CheckerPolice@gmail.com. Give me as much info as you can.
