System Crash takes out Chiller

[@HVACTIME]

I have produced a 6 page Technical Reference Guide. hvactime.shop/products/yk-tech-sheet

[@al.e123iis7]

I'm a software engineer. Did hvac during my undergrad and even an internship at carrier.. thinking of becoming an industrial tech soon. This office work is making me go crazy....

[@HVACChillin]

BAS COMPANY - “ It’s always the chillers fault. Our control system works flawless “ A lot places I work for always have a method of procedure written up to bypass BAS controls just in case stuff like this happens. Great video as always.

[@spikester]

The fact they can always tell the chiller is at fault when they only ever have two signal control wires to start & stop such a massive thing.... but never mind that its 2022 they deflect whatever it is they don't need to be aware of based on the system design simply not providing it in the first place.

Im still new to the industrial side. Coming from residential to comm/ industrial has been quite the eye opening experience. Im trying to learn as much as i can. I love this trade and i especially love the industrial side. In the year ive been on this side, ive learned i love the hydronics side and thats what i want to specialize in. Your videos are great, even if i dont understand some of it. I will become a proficient tech in industrial. I refuse to be average.

[@JD-hr6dr]

That's great that you are ambitious and want to learn, but none of the videos on this channel are truly industrial. This is what we refer to as "heavy commercial". Industrial HVAC/R companies don't deal with comfort cooling chillers such as this. They usually deal with : hydrocarbon process compression, ammonia refrigeration, recreational ice rinks, cold storage warehouses. The manufacturers and equipment they deal with: Mycom, Frick, Vilter, Howden, Sabroe, etc. On the heating side, we call it "process combustion", and it usually involves high pressure steam for things like pharmaceutical, food manufacturing, cement, steel, power generation, etc. Line heaters for pipelines. Boilers by Cleaver Brooks, Babcock and Wilcox, GE Boilers, or other industrial boiler manufacturers. They all use power burners, sometimes dual fuel. Gas valves and actuators by Maxon, everything 4-20 mA loops. Things like Viessmann, Wieshaupt, Riello, Aerco, RBI, Raypak are all considered commercial boilers/burners and you don't seem them in industrial applications You will never see that industrial equipment on this channel. It's a different part of the trade. Another key difference: heavy commercial deals with BMS (like in this video). Industrial applications usually stick with PLCs for process automation, not BMS systems. It's all cool stuff though.

[@HVACTIME]

@JD its true, I should probably do a better job at identifying that. When I first start a couple years back I was with another company and we had a lot of small industrial accounts. Its something I'm working us into at my current company. As you know its a tough market to get into.

[@jasonjohnsonHVAC]

@@JD-hr6dr we do have quite a few industrial customers and i understand what you said. To be honest here in Buffalo, most of our chillers are not for comfort cooling, they are for process cooling. Heating is a mixed bag of process and comfort here. We have a few places that have ultra high pressure steam. In excess of 1500 PSI and 800-1000° superheated steam. I haven't worked on any of that stuff yet.....but i set goals to get proficient enough to be able to. For me, i am a goal oriented type of person. I set goals to achieve and get good at, then i move on to the next challenge. I love challenges, its what keeps me going.

[@spikester]

@@jasonjohnsonHVAC I've learned a lot just the last few months, what mostly sets the two industries apart when it comes to the commercial comfort hvac vs industrial refrigeration/heating; especially the boilers, are the unions you are required to join when crossing the barrier. It dives right into the steam/pipefitters.

[@REFERTECH4U]

I just want to say that your videos awesome you seem very experienced I appreciate you passing on your knowledge thank you once again

[@EverythingHVACR]

Nice job! Always good information, keep up the good work 💪

[@creativetradesman6833]

No doubt York makes the best centrifugals. That’s a nice machine it’s got some good options. I’m glad to see some Caribbean Blue on your channel.

[@HVACTIME]

Wish I had more of them

[@houstonastrorider713]

Great video. Getting ready to start working on chillers.. definitely learning a lot. Thank you.

[@sreejithts9798]

very fine knowledge sharing about economizer system ,thanks

[@countrykid1640]

great video, except the NAE controller that you showed is for connected services and is connected to the elink on the upper left hand corner. it is on its own dedicated Port on the Elink. The BAS talks to the Elink directly on another port. The only thing that NAE is doing is taking the data from the chiller and sending it out on the attached modem and does not have any commands to send to the chiller. all of the BAS commands should go to the dedicated BAS port on the Elink card.

[@realestateservicessaleshea99]

We had siemans control in every week. 😆 up grades or glitches. That's why when people talk about how automated they want their home to be I just look and laugh. KISS ! KEEP IT STUPID SIMPLE! 🍺🍺🍺🥃🥃🍿🏌🏻‍♀️ New sub! Stay safe. Retired (werk'n)keyboard super tech. Wear your safety glasses.

Happy to have you in the community!

[@everestinspections9088]

great videos thank you

[@Erikmiles87]

In vegas, our water is so bad. Have to run the VSD water line to the evap. Condenser water pump plugs the heat exchanger faithfully and we lose our vsd to high temp

[@alimran657]

Can you please make a video on proximity diffreantial and thrust pad

[@realestateservicessaleshea99]

We also had a control panel that if automation goes down put everything in hand and what's not needed off and watch!

[@shivaHVAC]

How to replace vsop card for this chiller...any safety precautions need to take before?pls help

[@nategadow4482]

Great videos, thank you

[@JD-hr6dr]

Another great video, thanks for this. Just wondering if you ever work on modular chillers like Multistack, Arctic Chiller, ClimaCool, or niche chillers like Motivair or Smardt? It would be great to see content on that equipment.

[@HVACTIME]

Yes but it is pretty limited. We have been working to grow a presence in the industrial side as I get my team built. As of now just trying to keep up lol

[@stlbrian33]

Good job.👍

[@tonylaw196]

May be a defected sensor or high level interface offline cause the chiller plant go into economize mode. NAE would not switch the chiller directly, it should be through the FEC controller to switch on/off everything. NAE will be phase out and replace by SNE controller.

[@HVACTIME]

Its an extremely unusual setup. The NAE ties back to a Schneider system and its all kinds on not right lol. They have been putting off a new system for way to long. Hence a Sidewinder from 81 still in operation lol.

[@tonylaw196]

@@HVACTIME That may be offline between the NAE and Schneider system, mixing two brand BMS may cause the system unstable. I have a experience the NAE offline due to Schneider system keeping to ping the NAE and make it busy. I isolated the Schneider system and the NAE back to online. In this case, it should be replace the Schneider system to Johnson Controls system.

[@HVACTIME]

@@tonylaw196 I'd be good with that!

[@hectortorres542]

Thank you for the video very informative

[@ares3914]

Do a video on these York chillers. There very interesting and not common in my area so would like to see that

Have you got any jobs on the York YCWJ chillers? Or Carrier 19DG / 19XR chillers?

[@HVACTIME]

None that I have filmed

[@johnhanson4909]

You could just put the optiview in local control and start it

[@HVACTIME]

I was keeping it simple for the customer when the automation got fixed.

When you say ecominiser mode do you mean the rtu have eco mode settings or just a green thing. ?

[@HVACTIME]

They have a plant economizer using condenser water and chilled water

[@edwardgarza5104]

How is the chiller still running when you pulled the start stop relay? Is the chiller looking for a open circuit to start? Did you place it in hand? Or did I miss something? Thanks

[@edwardgarza5104]

I see now the relay is using a double pole double throw one normally open and one closed

[@HVACTIME]

@@edwardgarza5104 this chiller gets a start signal then it receives a stop signal when the automation shuts it down. After getting the signal it can loose the start contact and stay running as long as the stop contact doesnt close.

[@edwardgarza5104]

@@HVACTIME ok so both sets are on one relay? The start on the NO contact and the stop on the NC? Thanks for the response.

Is the old train chiller still R-11?

[@HVACTIME]

Yes

[@markefulton]

JCI NAE, there's your problem with the whole thing.

[@HVACTIME]

🤣🤣

[@James-vf5gs]

They should have made the remote stop relay fail safe, if the relay fails, the BMS cannot shut down the chiller.

[@realestateservicessaleshea99]

If the automation fails you just can't start a chiller (tower,condenser pumps,chiller pumps,ect) have to be on before that baby Cooks or big troubles ahead! Also they must have flow issues to bypass flow switches????
