System Crash takes out Chiller 

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.

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.

@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.

@@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.

@@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.

Wish I had more of them

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

Lol good one

Happy to have you in the community!

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

I appreciate the invite, just struggle with the time to do so

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.

@@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.

@@tonylaw196 I'd be good with that!

None that I have filmed

They have a plant economizer using condenser water and chilled water

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

@@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.

@@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.

@@edwardgarza5104 exactly

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UmNVXCZeOwo.html I explained that in this training.

Secondary chiller pump.

@@jasonjohnsonHVAC thank you do u mind translating all of them for me please

Yes

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????
