Condenser Pump And Motor Install With Some York YMC2 Surging Issues

30hp condenser motor and pump reinstalled for our York YMC2 chillers and now Chiller 1 is starting to surge… #hvac #york #chiller #controller

Lot to unpack with that one. That'll keep a guy busy for a little while. Good stuff broham.

[@subcoolHVAC]

This is a fun one, we’ll get it figured out. Thanks Jason 👊

[@BOBKB3NZX]

It's wild what you find from a system that was otherwise "running fine" one leg gets wobbly and then you uncover the house of cards

[@subcoolHVAC]

Yep, problems have a way of presenting themselves. 😎

[@trailerparkguns]

found your channel i love it. at a risk of sounding dumb is this a small part to a massive air conditioning system my local hospital has a massive set of evapco towers on a two story standalone building always wondered what it was for

[@subcoolHVAC]

Thanks for asking, yes these are the cooling towers for a couple of Centrifugal chillers (200 & 300 Ton) that cool many commercial buildings

[@Ericbakereb1]

Thanks for the video! Seems like we are going to see more of these Dork chillers. I'm not a fan of JCI

[@subcoolHVAC]

Lol, these replaced York R22 and R11 open drives.

[@thesilentonevictor]

Good find experience pays off

[@subcoolHVAC]

Thanks SilentoneVictor 👍

York ymc2 like to see as cold of condenser water as you can get 55 or 60 degrees but you are in florida

[@subcoolHVAC]

Entering CWT was set 85 , I know Yorks are able to run colder CWT

[@zekenzy6486]

Great Video. Thank you for sharing. Have a nice weekend. May I ask, Which's Refrigerant this chiller is using R22 or R410 A ? and second is: There are 2 sight glass , is those sight glass show refrigerant or water ?

[@subcoolHVAC]

Thanks, it’s R134a refrigerant. That is refrigerant seen in the sight glass.

[@HEFTYLEFTY303]

I would of liked to see where condenser liquid level setpoint was at

[@subcoolHVAC]

It was set at 38% not sure why, ran out of time troubleshooting… returning soon

[@jasonjohnsonHVAC]

@subcoolHVAC we have some YK's we had to adjust to 42% to get them to run right and not loose the liquid seal

[@subcoolHVAC]

I think 42% will do it. My access level wouldn’t allow me to change it. York and their Access Manager control 👎

[@jasonjohnsonHVAC]

@@subcoolHVAC I hat that access manager crap. I have the passwords for the ones they don't have their meathooks sunk into

[@jratti2006]

My good sir. What flashlight is that? And how’s the battery life?

[@subcoolHVAC]

Blackfire BBM6412 , rechargeable battery has good life, 2 levels of brightness is spotlight or lantern mode. Magnet is strong 💪

[@colossalsky]

Are these pumps for cold storage industrial buildings?

[@subcoolHVAC]

Condenser pumps for 2 York Centrifugal chillers used for Air Conditioning

[@colossalsky]

@@subcoolHVAC oh cool it’s interesting too see the different types of air conditioners, I work in a cold storage facility that’s cool the freezer with anhydrous ammonia that stuff is crazy scary

[@subcoolHVAC]

Never worked with Ammonia systems, toured a plant during apprenticeship many years ago. Impressive 👍
