CENTRIFUGAL CHILLER IS SURGING. SHOWING HOW TO PERFORM OIL FILTER REPLACEMENT ON RTHD.

[@Nighthawke70]

The thing about huge chillers, during cold starts like this, there will be some surging. I watched a clip of a 950 Ton Trane Centravac centrifugal that's older than you and me put together start up after a long winters nap and annual, and it was surging like a SOB. It took awhile, but it settled into a stable state and everyone was happy. The turbine on it is as big as most jet engine intakes!

Man,for years all I had was the Carrier 23xl/ 250 ton,6 in one bldg and 4 in another.You could not talk anywhere near the chiller room,they were sooooooo loud! Thx for the video

[@jasonjohnsonHVAC]

That RTHD is pretty loud.....but not as loud as the RTHB. Any screws are loud as hell. Centrifugals are thankfully much quieter.

Interesting vid JJ ... Thx

[@jasonjohnsonHVAC]

It was interesting. In my happy place around chillers

Just sign up for my HVAC school today, 12 weeks, wish me luck. 🤞🤞🤞🤞

[@Nighthawke70]

You need a TON more than that to set foot into a chiller. Your first jobs will be installing ducting.

[@jasonjohnsonHVAC]

I wish you good luck and much success

@@Nighthawke70 : But without school I'll go nowhere. Thanks for the heads up.

[@Nighthawke70]

@Android_Warrior I took two years at a technical college, got my universal and IMACA refrigerant usage cards, and they wanted to put my overweight butt up in attics to do ductwork, at best.

[@Elruido702]

I just finished a 12 month program I'm hoping not to start off as an installer everyones been saying that's where I'll start 😢

Nice job burping that big boy! 🫧👊 Keep em coming 👍

[@jasonjohnsonHVAC]

It still needs some work and it was struggling all day. It's quite humid here so she's struggling to make a dent on the building. Ended up shutting her down and firing up the other centrifugal after she started surging like 5 hours later. Thanks for the comment

[@subcoolHVAC]

@@jasonjohnsonHVAC I’ve seen them take a few days here, have to deal with high humidity too

[@NROhvac]

Good work

[@jasonjohnsonHVAC]

Appreciate the comment

[@nick29766]

This is the same chiller that HVACTIME had a serge and trip the power.

[@jasonjohnsonHVAC]

Yes sir. I work for the same company

First you need to take the purge out of adaptive. Dumbest thing ever. 7 psi at 27% should of told you that there was air in the machine. Oil pressure is extremely low for a Trane machine. Yeah surging, adaptive mode calculates how long and when it should run. Auto mode starts the purge when the machine runs. Adaptive mode was thought for electrical efficiency. Dumd idea.
