Startup On Centrifugal Chiller After Overhaul by HVAC Technician
Вставка
- Опубліковано 8 жов 2021
- Finally bring our centrifugal chiller overhaul to a close. This is a CVHF Trane chiller. We did a full motor overhaul, compressor, new drive assembly, and new control cabinet. This chiller was taken out and blew up during the 2021 February freeze in Texas.

When I started to work on commercial HVAC almost 30 years ago, I wanted to do chillers teardowns really bad, I thought that line of work was the pinnacle of the HVAC trade, then my dream came true but after 10 or so teardowns I got bored, its repetitive bullwork, definitely not for me, is good to know how to do it but the troubleshooting part of the trade is way more challenging and fun!
I’ve worked at a few shops that have chiller techs and they always hired guys with tear down experience and would pay them $50/hr plus (non union, years ago) and they never actually have to overhaul chillers lol that seems the way to go unless you work for trane or something
What's bullwork?
@Bunny Man like, bull in a China cabinet. Muscle required
@@kirkbodendorfer5313Interesting
Worked on 2000 ton centrifugals and absorbers over the years. But a 3 ton heat pump can kick my a**. Great video
Lol so true
Truer words have never been spoken, I had a 3 ton kick my ass last week my boss was like what is this to small for you lol
Smartest chiller guy I've ever known had his butt whooped by a walk-in cooler TXV. It happens. Residential, commercial, industrial, refrigeration; all different mindsets with different little tricks in each field.
I was the building engineer on site that had that chiller installed. Pretty cool to see a former plant and machines from a different point of view.
Its nice to see this finally come to fruition. I watched the videos on this chiller from start to end. Thanks for taking us on the journey with you.
Never worked on these before, worked on some chilled water and glycol units, ripening room racks but not these low pressure systems they look badass. Keep uploading these bud, thanks.
I starting working on ammonia for 6 years now I'm working on HVAC and Trane and bitzer chillers. I appreciate your videos they help me alot. I have a long way to go. Hopefully I'm as knowledgeable as you one day!
A few years back i worked with Trane to convert seven 850 Ton R11 machines to 124 4160V at Bristol Myers Squibb in Wallingford Ct eddy currant test condenser barrels the whole nine then they closed the plant two years later. Crazy … Awesome videos!!!
Great job on this chiller I work with York and g group chiller and York modules
Good video! Thank you
we had this one site where the chillers are 4160 vac 1200 tr chillers. they have carrier, york, trane and lg chillers. its a shouting match between the 4 chillers when they surge all the same time.
Great video buddy. Chiller looks good 👍
So, r u a chiller tear down and overhaul guy? U seem really sharp.
Good video buddy 👍
Very good sir
great job i would love to go to work for you do to all the diversity of thinks you work with stay safe MTT

If i lived in Texas id definitely like to work with you. Unfortunately im form Great Britain.
Thats a manageable commute right?
Why not set IFM’s to min flow rate?
Hello, from Cambodia. what is the AFD fault for Trane chiller?
Hi dude. I have a question. How can i get the TU software ?
Atmosphere? You mean non condensibles? What triggers the pump out on the purge unit? You have a warm suction slowly dropping, why does that happen?
I thought flow rate should be set at design min, no?
Yes on these chillers when we refer to atmosphere we are referring to non-condensables in the system. The suction temperature will slowly drop as the non-condensables stack in the evaporator not allowing proper heat transfer on The Purge unit meaning that it is time to pump out. The flow rate needs to be within design parameters at any given point I personally do not intentionally set them at design minimums I ensure that I am within the factory range and then if I need to fine tune it given a specific application I can do so.
Wished I lived there. I’d join your team in a heartbeat! Are you all only in Texas, or do you have other locations?
Just Austin and San Antonio Texas. Ever condenser relocating?
Your predictive text knows you well! Haha
My wife and I have been entertaining the thought. She just got her Nurse Practitioners’ License, and I’m ready for a change (pretty much topped out where I’m at. No room for growth).
Do you all have a website?

@@HVACTIME I could use a good job, I just signed a lease in dfw.... maybe soon I'll relocate.
How did you get that software? Link if possible please!? Thanks a mil!
Its on Trane's website, need to by subscription.
We work on a couple of these chillers and in pa Trane has there licenses locked down. How would you recommend to get a license for it
How does atmosfere air get into the closed system
The chiller is a low pressure machine, the evaporator is in a vacuum from 8"hg to 19"hg. Gaskets will allow atmosphere to pass through sometimes, just like a high pressure machine will leak refrigerant out from the chiller body to atmosphere.
I guess I'm in a different time ,but the operators should be side by side with you on start up?(stationary engineer)
