Corporate Facilities Group, Inc. Vice President of Operations Paul J. Hausleben takes you along on a typical rooftop inspection of a commercial building and has some fun with you too!
Paul, thanks so much for your video, it will help me a lot to understand the concepts you mentioned along the video having the plan, the PID diagram for full comprehension, I am not well versed on chillers but I am doing my best. I will appreciate your support.
You are welcome. Thank you for stopping by and taking the time to comment. Much appreciated.
Thanks! Great explanation!
Thank you!
total salesman here. who left you left alone in there?? 😂
I tend to wander! Thank you!
❤️💛💚❤️💛💚
Thank you!
That's very odd that you're using pneumatic actuator, so you need an air compressor for air supply. These Daikings chillers use R-134a refrigerant. Now I have a question, is this plant a load based system or a flow based? Are your AHU'S VALVE TWO WAY OR A THREE WAY VALVE SYSTEM? IF THE VALVES ON THE AHU'S THREE WAY IS A FLOW BASED SYSTEM. IF ITS A 2 WAY VALVE THEN ITS A LOAD BASED SYSTEM.
Hello. Thank you for your comments and questions. Yes, this plant does use pneumatic actuators and a very large multi-stage air compressors. The air is used in other applications in the facility. The building is very high and even with extensive lightning protection, we had terrible time with lightning strikes and surges. Many electronic devices in the plant are affected. We have found electronic actuators slightly fussy and unreliable. In over twenty years, even after retrofit, we have only had to rebuild two actuators. Very reliable. The system is load-based. It uses 2-way CW valves at the AHU's. Thank you again for your interest and joining us on the channel.
Ok you have a waterside economizer based on these plate and frame heat exchanger
Thank you for joining. Yes, you are correct.
Mr Paul what was evaporator your approach temperature on these chillers? 4-6°F approach
Thank you for your joining us and your question. I will need to pay more attention, but I would say you are very close at 4-6 degrees F. Perhaps, 3 to 5 F might be closer. I will say that the old R-11 Trane units, were capable of colder chilled water than these newer units are. It is not really noticeable in the building climate control or performance.
You should be getting a good Lift on with this chiller. Is your cooling tower a crossflow or counterflow type or evaporative tower.
Thank you for joining us and your comments and question. Usually the lift is solid; sometimes on colder days before we turn over to the economizer, the lift can vary a bit. Generally, the chillers are very solid and reliable. It is a crossflow tower.
Is this chiller facility a 14-18°F Delta T plant? What's your current COP? and how much kW/ton does it consume. Also what's the EER? I imagine you have either an airside or waterside economizer
Thank you for joining and for your comments and questions. You are close on the Delta T. Maybe 15 to 20 degrees is closer. Yes, we have a waterside economizer. I am not privy to any costs or electrical bills so I cannot comment on that with any accuracy. The building owners have commented that the electrical costs are much reduced (obviously) over the old chillers.
I tried calling your corporate headquarters in Atlanta Georgia but to no avail, I don't have your extension number. But Will continue to try
Thank you for joining. I am seldom in Atlanta. Please send us an email through the channel and I will try to assist.
My name is Gene Gonzalez and I welcome the opportunity to speak to you for any employment opportunity with your group
Thank you. Please send us an email through the channel and I will try to assist.
Hi Gene, please send me your email.
Almost the same layout as my plant but we use three York chillers screw type and our towers are further away and elevated. We also have the plate and air compressor.
Awesome! Thank you for joining.
Great
Thank you
Great walk thru.
Thank you
Good upload
you need to send this video out to every one to show them how a chiller plant should look CLEAN great job
Thank you! We do keep a very clean chiller plant and pride ourselves on keeping a building running in tip-top shape. It is not easy but we keep going around and around and around!
This guy sounds like Jack Nicholson
You said condensing pumps take water from condenser and pressure it to the cooling tower and this is wrong .. The condensing pump pressure cold water from cooling tower to condenser and it is found in return side from cooling tower to make sure there is always enough flow of water to absorb heat from hot gas refrigerant
Nesecito trabajo
Ok
I run in to this situation alot at work .. I hate those darn T's.. cable always goes across. But I found that putting a nice bend at the first few inches of my line helps guide cable down the "T" when I get to it .. also when it comes to commercial situations like this I always suggest that they remove the papertowel dispenser and replace with air blowers for hands . Eliminates the papertowls stoppages..
Thank you for your comment and interest in the video. Our crew is usually pretty good at guiding a snakes, drop heads, bends, etc. but this one was too tight and a no go. The tenants in the facility will not spring for the blowers, nor do they want them for a number of reasons. There are over twenty restrooms in this facility, therefore it is a major expense. However, the use of urinal screens has been a life saver. Now, housekeeping picks the towels off the screens, but at least, they do not get stuck in the waste lines!
To me you guys are heroes that's the toughest clog to get at.
Great video thanks!
You had the wall open, why didn't you add a cleanout on the vent of your cross fitting so if this reoccurs you're not having to open up tile again?
Hello Mike. Great question and thank you for your question and interest. We did try to add a clean-out to make this easier next time, but when we proposed it to building management, they refused due to aesthetic reasons.To be truly effective, we would have needed to add multiple clean-outs since there are multiple urinals in a row, and they share a common horizontal waste line. Since we now use urinal screens, and make sure that housekeeping always keeps up on them we have reduced the clogs to nil. Most often it was paper towels being flushed. Thank you.
Tell you what... that fitting looks like a combination y-tee and vent. I would have snaked it out from the vent stack on the roof and cleared that thing quick and easy.
Thank you for your reply and comment. This is a six story mid-rise and the vent stacks are not exactly lined up with the urinals. They have numerous ends and twists and are not direct home runs. Since this clog was on the lower floor, it would take one major snake just to reach the floor. Believe me, we investigated every angle before opening the wall.
@@corporatefacilitiesgroupin9291 You are welcome, but I must say, at six stories that's only about 60 vertical feet. I would have first tried a snake from the roof before cutting open a wall.
Just put urial screens in them.
They have them now! Thank you!
u should make that tile into an acces panel
We would have loved to have an access panel, but the owner of the building vetoed our idea.
u guys u sure u had to take all that apart to get the snake in...?
any hiring
thanks for the great video.. ive recently moved from a company that deal with more commercial refrigeration such as packs and condensing units to a company that look after AHUs and Water chillers and such so this video was a great help thanks
Lol, put a bend on the end of the cable.
We sure wished that was all it took! No go even with a drop head.
What is primary and secondary chiller pumps motor?
Still using pneumatic valves I see
Yes the electric actuators fail all the time. Those pneumatic valves are hard to beat as far as reliability and longevity. Looks like a nice facility. I'm always stuck working in shitholes with lack of maintenance. Those chillers say daikin mccquay, I hope they are better quality than these new daikin units that Goodman was putting out.
Thank you sir for your brief explanation the place where i work is its HVAC is functional but its system is very old i really wanna know about how new one are and this video showed me about new stuff related to HVAC :) i would be more glad to know how these chillers make chilled water as the place where i work it have lithium bromide absorption chiller i think the chillers u have works different thn the one i have seen, am i right?
video is good with explanation , which type of compressor??
Thank you. It is a Magnetic Bearing Centrifugal Chillers manufactured by Daikin Applied.
nice video ! fyi start at 3 minutes for explanation of the chiller functions
Good video Paul. keep sharing knowledge
Good explanation.
The HX plates, are they copper or SS ? The open loop will eat thru the thin cooper plate very fast.... they need the put a blanket on the HX and some sections of the open lOOp connecting to the HX .
Stainless steel plates. Thank you
Paul is a good talker
Holy Shit! Paul was my boss at minolta cameras
Some York YMC2 chillers would have been a better choice :) Cool video though! -York Chiller Mechanic
Derek Conner I have serviced /repaired them all and I must say York is by far the worst. They are quality , however their software is not user friendly and plagued with bugs. We've also had several issues with poor connections causing weird alarms that will come and go at their own will. Trane is by far the best platform. I do speak of equipment thats down in Florida. The high levels of humidity may come into play with my opinions on these machines. I don't know how yorks do up north.
Luigi Luigini Hmmmm that is interesting considering I have never had any of those particular issues with any York, water cooled or air cooled. I'm not biased, but I am master factory trained by York and know most issues that they bring a customer. I'm interested in the bugs, and connection issues. Are we talking about old York machines or newer? Huge difference between them.
Derek Conner Yes 15 + yr old YCAV Air cooled screw chillers. I may have exaggerated a bit but the York's are definitely the least user friendly for someone who is not specifically trained for York's.
Trane is what we use!
it is the bast chillar ever
Thank you for the valuable video and explanation
Nice video good job guys.can you reuse the same rubber gasket when you remount the urinal?
Thank you, Doug. I would not reuse the gasket. They are inexpensive and it is not worth having to pull the urinal a second time. We always keep a dozen or so in stock in the maintenance shop and simply change them out. We are glad that you enjoyed the video
thank you for taking the time to reply to my question. I guess it makes sense not to reuse the old gasket! again nice work and thanks for posting the video
very very important video of basic points
How many guys does it take to unclogg a urinal?
im going to correct you on a couple of misleading things in the video :) first of all its not important but the old refrigirant that you called r11 is achually called r12. and the newer gas that the new plant is using (r134a) is not toxic but it deprives oxygen in the room if there is a big leak so you will suffocate without even knowing that there is no breatable air in the room and possably die. that is why there is a saftey system in place. not saying this to be a smartass but i like pople to learn correct information. :)
Thank you for your interest in our video. I am going to have to say that while we appreciate your input, you are incorrect. The machines removed from this chiller plant were indeed 450 ton Trane R-11 machines. R-11 was used in old chillers frequently, and while it was a very good refrigerant, it was a ozone killer. Chillers of this type are low pressure appliances and R-11 was used. R-12 is primarily used in other appliances and applications. As far as toxic properties for 134a, a discharge in this plant of this amount of refrigerant would not be a good event. There is occupied office space below the plant. If there was a fire present, the 134a turns into a bad scene. Displacement of oxygen is toxic enough for me! Why take a chance? Treat all chemicals with care, read the safety sheet and limit exposures.
R-11 is a thing. If the man says he had it, we must believe him. However, the distinction that you make regarding the word toxic is significant. A toxic gas and an asphyxiant gas are thoroughly different, and the terms should not be used interchangeably, as they are responded to in completely different ways. These Magnitude 400D chillers should be charged with approximately 1240lbs of 134a each. Were one to rupture, it would dilute the oxygen (not necessarily displace, like argon) in that space greatly, posing a health risk. However, a toxic release would warrant a shutdown of air moving equipment to restrict its coverage, whereas an asphyxiant release would warrant the introduction of forced outside air. In any case, tell the chief he has a nice setup.

I buy R11 all the time and it is very possible that it was R11.
Thank You. You explained it all so much better than any of the guys I work with were willing too.
