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!

@AGON17 Год назад

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?

@kirkbodendorfer5313 Год назад

@Bunny Man like, bull in a China cabinet. Muscle required

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.

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.

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.

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!

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.

Great video buddy. Chiller looks good 👍

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!!!

@jarredallen Год назад

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.

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?

@OTHG6v 2 года назад

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?

@HVACTIME 2 года назад

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.

@kevinkozar5221 2 года назад

How does atmosfere air get into the closed system

@georgebrabec1749 2 года назад

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.
